0:00:02 > 0:00:06This programme contains scenes which some viewers may find disturbing.
0:00:06 > 0:00:09- NEWS REPORTS: - 'A former boarding school head
0:00:09 > 0:00:11'has been sentenced to 21 years in prison...'
0:00:11 > 0:00:14'The attacks happened between 1978 and 1983...'
0:00:14 > 0:00:18'..abused physically and sexually some of the boys in his care...'
0:00:18 > 0:00:23To his pupils, Derek Slade was an evil monster who
0:00:23 > 0:00:27repeatedly beat them and subjected them to sadistic sexual abuse.
0:00:27 > 0:00:33Back in 1982 we exposed some of this predatory pervert's activities
0:00:33 > 0:00:36in a BBC Radio 4 Checkpoint programme.
0:00:36 > 0:00:38'Whilst checking the dormitories after lights-out,
0:00:38 > 0:00:41'I frequently noticed boys missing from their beds.'
0:00:41 > 0:00:45But it took nearly 30 years for the full horror of Slade's history
0:00:45 > 0:00:49of sexual abuse to come to light and for him to be convicted
0:00:49 > 0:00:54on numerous counts of indecent assault and buggery on boys as young as eight.
0:00:56 > 0:01:02In the interim, he went on to steal the identity of a long dead boy in order to conceal his past.
0:01:02 > 0:01:08And he used that new identity to gain access to some of the most vulnerable children in the world.
0:01:08 > 0:01:11So, how many of you were beaten?
0:01:13 > 0:01:18I think we feel very pissed off by what this man was up to.
0:01:18 > 0:01:20So, how was he able to do it?
0:01:20 > 0:01:24How did he manage to escape justice for so long?
0:01:24 > 0:01:26And what finally brought him down?
0:01:43 > 0:01:46We've come to Suffolk.
0:01:46 > 0:01:50It's here where we first came across Derek Slade 29 years ago.
0:01:52 > 0:01:58It's where many of the 300 or so pupils in his care became his victims.
0:01:58 > 0:02:01We're on our way to meet two of them.
0:02:01 > 0:02:06Men now almost 40, whose courage and persistence was instrumental
0:02:06 > 0:02:08in bringing him to justice.
0:02:08 > 0:02:11They've agreed to meet us at the school where they were abused
0:02:11 > 0:02:15at Great Finborough, near Stowmarket in Suffolk.
0:02:15 > 0:02:20And that's where Checkpoint first exposed this appalling story all those years ago.
0:02:22 > 0:02:26'Some people were made to sort of swap clothes or take all their clothes off.'
0:02:26 > 0:02:33'The whole of his backside was covered in bruises of every colour.'
0:02:37 > 0:02:42The revelations of Slade's harsh and violent regime at St George's
0:02:42 > 0:02:43made national headlines
0:02:43 > 0:02:46as newspapers followed our lead in reporting them.
0:02:48 > 0:02:51Slade denied the allegations, claiming that the press
0:02:51 > 0:02:55were out to get him and, for a while, he hung on to his post.
0:02:56 > 0:02:58I just don't believe it.
0:02:58 > 0:03:03I feel that a great deal has been overstated
0:03:03 > 0:03:05and very substantially overstated.
0:03:08 > 0:03:11But it wasn't.
0:03:11 > 0:03:15This is where the abuse took place, St George's.
0:03:15 > 0:03:17It's now called Finborough School.
0:03:17 > 0:03:20And though it's still owned by the same company,
0:03:20 > 0:03:22it's now under different management.
0:03:22 > 0:03:26Mike Parker was 10 years old when he was first sent here.
0:03:26 > 0:03:30Only now can he bring himself to talk about it.
0:03:30 > 0:03:33Within 72 hours of being at the school
0:03:33 > 0:03:36I basically had the shit kicked out of me by Derek Slade.
0:03:36 > 0:03:38What did he do?
0:03:38 > 0:03:42He just went ballistic. I'd been called to his office and he just laced into me.
0:03:42 > 0:03:46- I had no idea at all why he was doing it.- And now?
0:03:46 > 0:03:50Now, with hindsight, I believe it was all part
0:03:50 > 0:03:55of the regime of him breaking me for things that were to come.
0:03:55 > 0:03:58- And what was to come?- The abuse.
0:03:58 > 0:04:03Wayne Makin was in the same year as Mike.
0:04:03 > 0:04:07First time he told me to take my trousers and pants down, I was like, "What?"
0:04:07 > 0:04:08But you didn't argue.
0:04:08 > 0:04:12Because you soon learnt that if you didn't do as you were told,
0:04:12 > 0:04:17just wind your neck in, get your head down and get on with it,
0:04:17 > 0:04:19then it just gets worse.
0:04:19 > 0:04:22- You were being conditioned, really? - Yeah, basically.
0:04:22 > 0:04:25Conditioned for the real horrors that were to come
0:04:25 > 0:04:31and for secret midnight feasts at Slade's house.
0:04:31 > 0:04:32What happened there?
0:04:32 > 0:04:38We were entered into the dining room and we was to stand
0:04:38 > 0:04:42against the back wall and serve the five gentlemen who were already there.
0:04:42 > 0:04:46And when they'd finished drinking and eating, one by one,
0:04:46 > 0:04:49the gentlemen would approach one of the children
0:04:49 > 0:04:52and touch him on the shoulder and move to another part of the house.
0:04:52 > 0:04:57I can remember going to the feasts and being taken off with a man.
0:04:57 > 0:04:59But I was given something to drink
0:04:59 > 0:05:02and I can't remember anything that happened to me.
0:05:02 > 0:05:05But I know something did happen to me.
0:05:05 > 0:05:09But whether I've buried it so deep, cos it was so traumatic or...
0:05:09 > 0:05:11You know, that's the only thing.
0:05:11 > 0:05:14Maybe it's a good thing that I can't remember
0:05:14 > 0:05:18because it's hard enough as it is, bringing all this up again.
0:05:18 > 0:05:20When you were selected, what happened?
0:05:20 > 0:05:24Some people would probably say that I was raped.
0:05:24 > 0:05:29But I was so mentally submissive
0:05:29 > 0:05:32that it was almost
0:05:32 > 0:05:34like I allowed it to happen.
0:05:34 > 0:05:36There was nothing I could do about it.
0:05:36 > 0:05:39The beatings would come afterwards if I didn't comply.
0:05:39 > 0:05:41What's it done to your life?
0:05:41 > 0:05:43Basically, just ruined it.
0:05:43 > 0:05:48I tried to commit suicide within six months of leaving the school.
0:05:48 > 0:05:54And I wasn't really... I was totally on a self-destroy.
0:05:54 > 0:05:57I'm a loner.
0:05:57 > 0:05:59Several failed relationships.
0:05:59 > 0:06:02I've tried time and time again.
0:06:02 > 0:06:04And it's just been
0:06:04 > 0:06:10a continuous barrage of problem, after problem, after problem.
0:06:10 > 0:06:13Slade abused scores of boys at St George's
0:06:13 > 0:06:16and ruined at least as many lives.
0:06:16 > 0:06:18He was forced to resign.
0:06:18 > 0:06:23But it wasn't long before he'd set up another school, this time in Sussex.
0:06:26 > 0:06:30And, a few years later, he was back in the news again.
0:06:30 > 0:06:34'Derek Slade, the headmaster of the Dalesdown private school in Sussex,
0:06:34 > 0:06:35'on the left in this picture,
0:06:35 > 0:06:39'has been sentenced to three months imprisonment at Chichester Crown Court.'
0:06:39 > 0:06:43'In both cases, the court heard the boys were taken to a private room, the door was locked,
0:06:43 > 0:06:46'the curtains were drawn they were ordered to remove their trousers and underclothes.
0:06:46 > 0:06:52'Then the head administered six blows so severe that the markings were clearly visible days later.'
0:06:52 > 0:06:58'The court was told that Mr Slade's career in education was finished beyond all doubt.'
0:06:58 > 0:06:59But it wasn't.
0:06:59 > 0:07:04He wasn't even banned from teaching, though his conviction stood.
0:07:04 > 0:07:06Slade's sentence was reduced
0:07:06 > 0:07:09to a conditional discharge by an appeal court judge
0:07:09 > 0:07:13who described his crimes as "lapses of an isolated nature."
0:07:13 > 0:07:18Although the trial judge had called his assaults "sickening."
0:07:18 > 0:07:22But as our six month long investigation will show,
0:07:22 > 0:07:27Slade would go on to abuse more children in India and Africa,
0:07:27 > 0:07:30by exploiting those he knew in high places.
0:07:30 > 0:07:34The most significant of these was Derek Sawyer.
0:07:34 > 0:07:39He became an important factor in Slade's future employment in schools.
0:07:39 > 0:07:44He'd been a character witness for Slade in the Dalesdown trial, telling the court
0:07:44 > 0:07:48Slade was a well-liked teacher who believed corporal punishment
0:07:48 > 0:07:50was an effective aid to discipline.
0:07:50 > 0:07:53Mr Sawyer was an important figure in the Labour Party,
0:07:53 > 0:07:58elected as a councillor in the London borough of Islington in 1982.
0:08:00 > 0:08:05Here he is on Kilroy, arguing for more police accountability.
0:08:05 > 0:08:10How can we have confidence in a police force that can't even find out
0:08:10 > 0:08:15if one of their own men had done something?
0:08:17 > 0:08:20He went on to become Party Secretary
0:08:20 > 0:08:24and then Leader of the Council for six years from 1992.
0:08:24 > 0:08:29In that position, he oversaw the official inquiry into a paedophile ring
0:08:29 > 0:08:34which had infiltrated all 12 of the council's children's homes.
0:08:34 > 0:08:37More recently, Mr Sawyer took up key positions
0:08:37 > 0:08:41on bodies running London's police, magistrates and probation services.
0:08:45 > 0:08:47Mr Sawyer didn't want to be interviewed.
0:08:47 > 0:08:52But, through his lawyer, he says that the Schools' Inspectorate didn't find evidence at St George's
0:08:52 > 0:08:56to support the claims made in the Checkpoint programme.
0:08:56 > 0:08:59He wasn't to know, of course, that the Inspectorate had failed
0:08:59 > 0:09:04to properly investigate our evidence by not interviewing key witnesses.
0:09:04 > 0:09:07And some of the pupils they did interview
0:09:07 > 0:09:09had been told what to say by Slade.
0:09:09 > 0:09:14He also says he didn't know that Slade could not be trusted with children
0:09:14 > 0:09:17because he wasn't charged with any sexual offences at Dalesdown.
0:09:17 > 0:09:23He adds that he was convinced that the allegations of excessive use of corporal punishment at Dalesdown
0:09:23 > 0:09:27were exaggerated, and he doesn't agree with corporal punishment himself.
0:09:31 > 0:09:34But how close were these two men?
0:09:34 > 0:09:38And should Mr Sawyer have known that his controversial friend's
0:09:38 > 0:09:41previous use of excessive corporal punishment
0:09:41 > 0:09:43could pose a risk to children?
0:09:46 > 0:09:48Our investigation has revealed
0:09:48 > 0:09:52that the two of them had been friends for more than 40 years.
0:09:52 > 0:09:56They'd been at school together in the mid 1960s.
0:09:56 > 0:10:01Here's a postcard sent from Mr Sawyer to Slade in 1967.
0:10:01 > 0:10:06Slade used to boast that he was the best man at Mr Sawyer's wedding.
0:10:09 > 0:10:15Periodically, Mr Sawyer was involved in no fewer than four businesses with Slade.
0:10:21 > 0:10:25Perhaps the most significant of these companies was IBEP.
0:10:25 > 0:10:29That stands for International British Education Projects.
0:10:29 > 0:10:32Motto: "Serving the world's children everywhere."
0:10:32 > 0:10:37Slade was a director and Mr Sawyer was the company secretary and chairman.
0:10:39 > 0:10:41Slade would go on to exploit IBEP
0:10:41 > 0:10:46to gain renewed access to children years after his conviction.
0:10:46 > 0:10:50But there was also someone else involved with this company.
0:10:50 > 0:10:53Somebody called Edward Marsh.
0:10:53 > 0:10:56Described as an eminent educationalist,
0:10:56 > 0:10:58Edward Marsh wrote textbooks
0:10:58 > 0:11:00which were published by Oriflamme,
0:11:00 > 0:11:01another company of which
0:11:01 > 0:11:04Derek Slade and Derek Sawyer were co-directors.
0:11:04 > 0:11:07But who was Edward Marsh?
0:11:09 > 0:11:12At the time of Slade's first criminal conviction, remember,
0:11:12 > 0:11:17it was said that it would be difficult, if not impossible for him to teach again.
0:11:18 > 0:11:22To solve that problem, he had to reinvent himself.
0:11:22 > 0:11:25He had to create another identity.
0:11:25 > 0:11:30He came here to Nottingham Road Cemetery in Derby.
0:11:30 > 0:11:34And, following a scam described in the thriller The Day Of The Jackal,
0:11:34 > 0:11:38he was looking for someone who would have been about his age had he lived.
0:11:38 > 0:11:41Somebody he could pretend to be.
0:11:42 > 0:11:49And he found what he was looking for on the gravestone of eight-year-old Edward Marsh.
0:11:49 > 0:11:52Slade obtained a copy of the dead boy's birth certificate.
0:11:52 > 0:11:56Armed with this and a self-certified photo of himself
0:11:56 > 0:11:59he successfully applied for a passport in Edward's name.
0:11:59 > 0:12:02It was as simple as that.
0:12:02 > 0:12:05And as Edward Marsh he was to land a new job
0:12:05 > 0:12:08on the other side of the world.
0:12:17 > 0:12:21We're in Big Bend, a company town in Swaziland.
0:12:23 > 0:12:26In 2000, Slade and Sawyer's company, IBEP,
0:12:26 > 0:12:30was awarded the contract to run four schools here.
0:12:30 > 0:12:36And who should turn up as IBEP's Director of Education
0:12:36 > 0:12:38but a Dr Edward Marsh.
0:12:38 > 0:12:41It wasn't just his name that was false.
0:12:41 > 0:12:44So was his claim to have a doctorate.
0:12:44 > 0:12:48He'd got the job with the help of Mr Sawyer who, as Chairman of IBEP,
0:12:48 > 0:12:52submitted this glowing endorsement for Edward Marsh.
0:12:52 > 0:12:56Mr Sawyer says he gave an accurate recommendation in good faith,
0:12:56 > 0:12:57which did not refer to the doctorate,
0:12:57 > 0:13:01and that his role didn't give Slade direct contact with children.
0:13:01 > 0:13:02He also says Slade told him
0:13:02 > 0:13:06he'd legally changed his name to Edward Marsh by deed poll.
0:13:08 > 0:13:10But it remains to be explained why both names,
0:13:10 > 0:13:12Derek Slade and Edward Marsh,
0:13:12 > 0:13:17continued side by side on IBEP's company paperwork.
0:13:19 > 0:13:24The schools were founded and funded by Ubombo Sugar,
0:13:24 > 0:13:25the largest local employer
0:13:25 > 0:13:29and now a subsidiary of Associated British Foods.
0:13:32 > 0:13:37Slade lived behind these gates at the Ubombo Sugar guest house.
0:13:37 > 0:13:42It's outside the town in isolated farmland.
0:13:42 > 0:13:46He was often seen by locals driving young Swazi boys
0:13:46 > 0:13:49to and from his lodgings after school hours.
0:13:49 > 0:13:54There was absolutely no reason for him to be bombing down the dirt road
0:13:54 > 0:13:56with all these young boys in his car.
0:13:56 > 0:14:00And it really did raise the alarm bells for me.
0:14:00 > 0:14:05As a parent, Kathy Hughes wasn't the only one worried
0:14:05 > 0:14:09about inappropriate behaviour by Slade.
0:14:09 > 0:14:15So too was the sugar company's Chief Medical Officer, Dr Tim Nunn.
0:14:15 > 0:14:17Inside the medical consultation
0:14:17 > 0:14:20I saw four or five children who alleged abuse.
0:14:20 > 0:14:25The allegations of abuse were mainly physical and sexual in nature,
0:14:25 > 0:14:29fondling and excessive corporal punishment.
0:14:31 > 0:14:37Though he believed these allegations, Dr Nunn didn't report them to Ubombo or even the police.
0:14:37 > 0:14:41He says he was constrained by patient confidentiality.
0:14:41 > 0:14:43If he had been able to report them,
0:14:43 > 0:14:47Slade might have been caught there and then.
0:14:47 > 0:14:51Slade had contrived to gain access to children once more,
0:14:51 > 0:14:54but he was about to make a crucial mistake.
0:14:54 > 0:14:57He issued this new rule book for the school.
0:14:57 > 0:14:59It said that as Director of Education
0:14:59 > 0:15:02he would be allowed to beat pupils at his discretion -
0:15:02 > 0:15:07a reminder that that this particular leopard hadn't changed its spots.
0:15:07 > 0:15:10The school had never used corporal punishment before
0:15:10 > 0:15:13and there was outrage among parents and teachers.
0:15:13 > 0:15:17It all came to a head at a parents' meeting at Sisekelo.
0:15:17 > 0:15:20We're told that Derek Sawyer was there
0:15:20 > 0:15:22and heard the concerns of parents.
0:15:22 > 0:15:25But Mr Sawyer says he wasn't at this particular meeting,
0:15:25 > 0:15:27he wasn't aware of the rule book,
0:15:27 > 0:15:30didn't know that Slade had access to children
0:15:30 > 0:15:31or that there were any concerns
0:15:31 > 0:15:34about his inappropriate behaviour towards them.
0:15:37 > 0:15:41Although he'd changed his name, Slade couldn't change his nature.
0:15:43 > 0:15:48Just six months after he got the job in Swaziland he was asked to leave.
0:15:48 > 0:15:54And when he did, no-one there had any idea of his past or his real identity.
0:15:54 > 0:15:56The reason for Marsh's dismissal
0:15:56 > 0:16:00was his management incompetence and abrasive style.
0:16:06 > 0:16:09But Slade still craved access to children.
0:16:09 > 0:16:13What he did next would show how far he would go.
0:16:14 > 0:16:20In January 2001 a massive earthquake struck the Indian State of Gujarat,
0:16:20 > 0:16:25killing 20,000 people and leaving 200,000 homeless.
0:16:25 > 0:16:30British charities soon began raising money to help the victims.
0:16:30 > 0:16:34Slade saw his chance and used IBEP and his contacts
0:16:34 > 0:16:36to exploit the situation.
0:16:42 > 0:16:44This is the village of Nana Layja.
0:16:44 > 0:16:48It was completely destroyed by the quake but has now been rebuilt
0:16:48 > 0:16:52thanks to the Leicester Gujarat Earthquake Relief Fund.
0:16:52 > 0:16:56Keen to ride a wave of public sympathy, Derek Slade,
0:16:56 > 0:16:58in his original name,
0:16:58 > 0:17:01approached the earthquake fund offering to set up a school
0:17:01 > 0:17:04for the many children orphaned by the disaster.
0:17:04 > 0:17:08He twice met trustees of the fund to pitch his proposal.
0:17:08 > 0:17:11Although this wasn't an IBEP project, he brought along
0:17:11 > 0:17:13his old friend Derek Sawyer,
0:17:13 > 0:17:16Chairman of IBEP, to one of those meetings.
0:17:16 > 0:17:19The trustees say they were bowled over.
0:17:19 > 0:17:22Derek Slade and Derek Sawyer came to the offices.
0:17:22 > 0:17:24I think it was very, very impressive
0:17:24 > 0:17:27in terms of the portfolio that was brought in,
0:17:27 > 0:17:30the work around Africa,
0:17:30 > 0:17:34the 16...or 8-year work they'd done in India.
0:17:34 > 0:17:37Derek Slater had, in particular.
0:17:37 > 0:17:42And the articulation in terms of heading up such an establishment,
0:17:42 > 0:17:47it was an ideal opportunity for us to be able to see that somebody
0:17:47 > 0:17:50would be able to manage our project in India.
0:17:50 > 0:17:54But should Mr Sawyer, by his presence, have lent support
0:17:54 > 0:17:57to Slade's pitch to the earthquake fund
0:17:57 > 0:17:59and not told them about his past?
0:17:59 > 0:18:04By now you'd think that alarm bells might have been ringing for Mr Sawyer.
0:18:04 > 0:18:07There was the Radio 4 Checkpoint programme
0:18:07 > 0:18:09and Slade's conviction in Sussex.
0:18:09 > 0:18:15And then there was the row at Sisekelo over his attempt to authorise corporal punishment.
0:18:19 > 0:18:25So, what did Slade really do with the £85,000 generously donated
0:18:25 > 0:18:28by the good people of Leicester? We've come to find out.
0:18:30 > 0:18:33This is the school Slade built.
0:18:33 > 0:18:37It's nowhere near Nana Layja but miles away on this completely
0:18:37 > 0:18:42isolated stretch of scrubland, far away from prying eyes.
0:18:44 > 0:18:47None of Slade's 70 pupils are here any more.
0:18:47 > 0:18:50But it didn't take long for us to track some of them down
0:18:50 > 0:18:54at a religious school in a neighbouring town.
0:18:54 > 0:18:57So, how many of you were beaten by Slade?
0:19:01 > 0:19:04All of you?
0:19:04 > 0:19:08- TRANSLATION:- He hit me with the stick, other times with his hands.
0:19:08 > 0:19:11- TRANSLATION:- He used to beat us every Sunday.
0:19:11 > 0:19:15He used to beat us, then take photos, then offer chocolate.
0:19:15 > 0:19:20He'd rub you afterwards and say nothing had happened.
0:19:20 > 0:19:24And such is the shame of male sexual abuse in rural India
0:19:24 > 0:19:27that none of the boys would go into further detail.
0:19:27 > 0:19:31But their carers are certain they were abused.
0:19:35 > 0:19:39None of the boys we found were orphans of the earthquake
0:19:39 > 0:19:41as Slade had claimed.
0:19:41 > 0:19:45Instead, they came from the remote and impoverished village of Bhagadya
0:19:45 > 0:19:49where the largely illiterate locals had jumped at the chance
0:19:49 > 0:19:51to have their sons educated for free.
0:19:51 > 0:19:54But when we told them what Slade had really been up to,
0:19:54 > 0:19:56they were dumbfounded.
0:19:58 > 0:20:02TRANSLATION: We still cannot believe that any teacher could do this.
0:20:04 > 0:20:07This kind of thing is unheard of in India.
0:20:07 > 0:20:13And if it is true, then our village and our children have been betrayed.
0:20:13 > 0:20:17For five years, Slade ran this school unhindered.
0:20:17 > 0:20:21But in 2008 he suddenly left.
0:20:21 > 0:20:24We're told someone had caught him beating a child
0:20:24 > 0:20:27and had reported him to the local police.
0:20:27 > 0:20:30Some of the possessions he left behind in his locked bedroom
0:20:30 > 0:20:35indicate just how quickly he'd departed.
0:20:35 > 0:20:37The door may have been locked, but the window was open.
0:20:37 > 0:20:39And on a table just inside
0:20:39 > 0:20:42we found three of Slade's instruments of punishment.
0:20:42 > 0:20:46One, this cane, and two of these so-called Jokari bats.
0:20:46 > 0:20:49One made from hard rubber, the other from hard wood.
0:20:49 > 0:20:52The other significant thing about this bedroom
0:20:52 > 0:20:55is that the boys' dormitories are right next door.
0:21:03 > 0:21:06But while Slade was still headmaster here,
0:21:06 > 0:21:08he made another crucial mistake -
0:21:08 > 0:21:12one that would ultimately lead to his arrest in 2010.
0:21:14 > 0:21:18Signing himself Edward Marsh, he wrote a letter in 2005
0:21:18 > 0:21:25to Derrick Pereira - the UK chairman of the charity Help A Poor Child.
0:21:25 > 0:21:30In it, he suggests meeting up to discuss working together on another project.
0:21:38 > 0:21:41According to Mr Pereira the meeting duly took place,
0:21:41 > 0:21:46with Slade's friend and sometime business partner Derek Sawyer in attendance,
0:21:46 > 0:21:49here at Mr Sawyer's North London home.
0:21:51 > 0:21:58It was supposed to be an opportunity to meet the eminent educationalist and philanthropist Dr Edward Marsh.
0:21:58 > 0:22:01Mr Pereira says he was hugely impressed.
0:22:01 > 0:22:03But halfway through the meeting
0:22:03 > 0:22:06there appeared to be some confusion over names.
0:22:06 > 0:22:09Derek Sawyer referred to Edward Marsh as Derek Slade.
0:22:09 > 0:22:15I was confused by this and asked what this was about.
0:22:15 > 0:22:17And they said it was a pseudonym he was using
0:22:17 > 0:22:21as part of a best-selling book they'd written a little while ago.
0:22:21 > 0:22:25We couldn't trace the best-seller to which Mr Pereira refers.
0:22:25 > 0:22:29But we did find another rather unsuccessful book
0:22:29 > 0:22:32published by their company Oriflamme, in 1985.
0:22:32 > 0:22:34And this is it.
0:22:34 > 0:22:37It's a children's book, and a pretty bloodthirsty one at that.
0:22:37 > 0:22:40But it wasn't written by Edward Marsh.
0:22:40 > 0:22:43It was penned by someone called Derek Sawde.
0:22:43 > 0:22:50That's a combination of both men's names, and it's dedicated to both their parents.
0:22:50 > 0:22:53Mr Sawyer didn't want to comment about the book.
0:22:53 > 0:22:57He also says the meeting with Derek Pereira
0:22:57 > 0:23:00didn't take place as described.
0:23:00 > 0:23:04Despite the confusion over names, Derrick Pereira was persuaded
0:23:04 > 0:23:08by Slade to give him £18,000 of the charity's funds.
0:23:08 > 0:23:12He also made him its representative in India.
0:23:12 > 0:23:15But a year later he received an alarming email
0:23:15 > 0:23:17from a former pupil at St George's
0:23:17 > 0:23:21who'd seen this information on the charity's website.
0:23:21 > 0:23:24What did this ex-pupil tell you?
0:23:24 > 0:23:29That we had to be very careful because we were dealing with a man who had previously
0:23:29 > 0:23:35abused children at St George's School back in the '70s.
0:23:35 > 0:23:38Naturally we were appalled by what we heard,
0:23:38 > 0:23:41so we informed our branches in India
0:23:41 > 0:23:46to investigate further into Derek Slade and the affairs of the school.
0:23:46 > 0:23:49Soon afterwards, the charity issued
0:23:49 > 0:23:52this carefully worded statement on its website.
0:23:52 > 0:23:58We were withdrawing all of our support, disassociating ourselves from Derek Slade
0:23:58 > 0:24:05and we were looking to recover our funds and to safeguard the children that were under his care.
0:24:05 > 0:24:08Carefully worded the statement may have been,
0:24:08 > 0:24:11but the posting still had an impact.
0:24:11 > 0:24:15It was seen by another organisation on the other side of the world.
0:24:15 > 0:24:18The Sisekelo High School in Swaziland got in touch,
0:24:18 > 0:24:23asking what the charity knew about a Dr Edward Marsh.
0:24:23 > 0:24:27When they heard what we had to tell them, they dropped the phone.
0:24:27 > 0:24:29They couldn't believe what they were hearing,
0:24:29 > 0:24:34in particular that Edward Marsh and Derek Slade was the same person.
0:24:34 > 0:24:40Of course when we heard what they had to tell us, we were appalled about what had gone on in Swaziland.
0:24:44 > 0:24:47Years after we'd exposed this man's harsh
0:24:47 > 0:24:52and violent regime at St George's, he was still involved with children.
0:24:52 > 0:24:59And despite being convicted in 1986 of causing actual bodily harm to two pupils in his care,
0:24:59 > 0:25:03he'd still managed to gain access to children in Africa and India,
0:25:03 > 0:25:06where the appalling abuse continued.
0:25:06 > 0:25:09But what was it that finally brought him down?
0:25:18 > 0:25:21For Mike Parker, 26 years on,
0:25:21 > 0:25:26the nightmare of St George's had returned.
0:25:26 > 0:25:29I just woke up screaming, shouting and balling.
0:25:29 > 0:25:31I then realised I'd wet myself.
0:25:31 > 0:25:3438 years old,
0:25:34 > 0:25:36it just doesn't happen.
0:25:38 > 0:25:40I came into the living room
0:25:40 > 0:25:45and just grabbed a ream of paper and just started writing.
0:25:45 > 0:25:49He made contact with some of Slade's other victims from St George's
0:25:49 > 0:25:53through Facebook, and they took their testimonies to the police.
0:25:53 > 0:25:56I was duty bound. I had a job to do.
0:25:56 > 0:25:57And as far as I was concerned,
0:25:57 > 0:26:01because I hadn't spoken out previously, that man hadn't been stopped.
0:26:01 > 0:26:04I couldn't believe he was still involved with children.
0:26:04 > 0:26:07Some of the stuff I was reading on the internet clearly showed
0:26:07 > 0:26:10that he was still involved in what he'd been doing previously.
0:26:10 > 0:26:16Their evidence was collated and in what became something of a perfect storm on three continents,
0:26:16 > 0:26:23the Suffolk police began an investigation that eventually led to Slade's arrest.
0:26:23 > 0:26:26Here at Slade's house in Burton-on-Trent,
0:26:26 > 0:26:28police found 70,000 images of children,
0:26:28 > 0:26:30some from India, some from Africa.
0:26:30 > 0:26:344,500 of them were deemed to be obscene.
0:26:34 > 0:26:38They also recovered audio tapes of boys being beaten,
0:26:38 > 0:26:40boxes of highly explicit material
0:26:40 > 0:26:44and detailed diaries of punishments inflicted at St George's
0:26:44 > 0:26:46written in ancient Greek.
0:26:47 > 0:26:49Evidence from Swaziland and India,
0:26:49 > 0:26:53together with heart-rending testimony from numerous victims
0:26:53 > 0:26:56of his reign of terror at St George's
0:26:56 > 0:27:00finally led to Slade's conviction and a 21-year sentence.
0:27:00 > 0:27:04Slade clearly exploited his friendship with Derek Sawyer,
0:27:04 > 0:27:06a man prominent in public life.
0:27:06 > 0:27:11He'd been leader of Islington Council, chairman of the London Courts Board
0:27:11 > 0:27:15and director of the crime prevention charity Catch 22.
0:27:17 > 0:27:19Just the sort of man, you might think,
0:27:19 > 0:27:21who ought to have made it his business
0:27:21 > 0:27:24to ask more questions about his controversial friend.
0:27:24 > 0:27:27But it seems he did not.
0:27:27 > 0:27:31Mr Sawyer, didn't want to talk to us, remember.
0:27:31 > 0:27:35Instead, as his lawyers say in the short statement issued on his behalf,
0:27:35 > 0:27:38their client was kept in ignorance by Mr Slade.
0:28:16 > 0:28:22It seems our radio programme of 30 years ago uncovered the tip of a substantial iceberg.
0:28:22 > 0:28:25As we've discovered, Derek Slade himself went on to abuse
0:28:25 > 0:28:28countless more children on two more continents.
0:28:28 > 0:28:33His conviction prompted the police to open a new investigation.
0:28:33 > 0:28:37And for Mike Parker, too, the quest for justice goes on.
0:28:39 > 0:28:41There's no way on God's good earth
0:28:41 > 0:28:45that I can now sit back and say, "Hey, I'm happy."
0:28:45 > 0:28:47The police have only taken this so far.
0:28:47 > 0:28:49They've got so much more work to do.
0:28:49 > 0:28:52And I will not let up.
0:28:52 > 0:28:55I can't. This has now become my life.
