On 19 May 1976, The Daily Telegraph published a story under the headline: "Campaign in US to smear MPs". Wallace also attempted to draw public attention to the Kincora Boys' Home sexual abuse scandal several years before the Royal Ulster Constabulary finally intervened.

Cavendish, a close friend over many years of Sir Maurice Oldfield, former Chief of the Secret Intelligence Service, says that Wallace's assertion that Oldfield was the target of a black propaganda campaign by MI5, "match closely details which were told to me privately by Maurice.I believe there are many people in high places and within the security services who feel ill-will towards Wallace for exposing their activities. Writing in the New Statesman in 1986, Duncan Campbell revealed that, at about the time Wallace was charged with manslaughter, intelligence officers wrote to Sir Frank Cooper, Permanent Under Secretary of State at the Ministry of Defence, warning him that "Wallace had both the information and the motivation to reveal the story behind Kincora".

A former Ministry of Defence Chief Information Officer commented: "For loyalty and dedication to the Army, Colin Wallace was in a class of his own. It’s not an easy place to pass people either, unclipping from the safety line with a 2,000m drop behind you is seriously not cool.Taking you through various parts of Colin Wallace’s life by theme and related events, rather than specific time periods, weaving narrative that is somewhat unbelievable but is, for the majority confirmed true by the end of the book. In 1969, The Irish Guards Association Journal carried this reference to Wallace: "He is a great training enthusiast and is never happier than when he is on top of one 3,000-foot peak busily engaged in plotting his hop to the next one. What Wallace was unaware of was that McGrath and McKeague had virtual immunity from prosecution because of the information they were supplying to their Intelligence bosses. It was very much a matter that, OK the story was being contained at the moment because he was in jail, but that in a few years' time he would be back out again and could be expected to start making the allegations again and then that would be a serious problem.

The boy had told RUC officers that sexual assaults were taking place at the home and, although they were sympathetic, the officers told her that they were being blocked at a higher level from doing anything. He told the reporters that he believed members of MI5 had been involved in a plot to undermine his Government. That Inquiry would be led by a retired circuit judge, Judge William Hughes [23] and it was decided that "It will be up to the Inquiry and the eminent judge who will preside over it to examine anything which is relevant to the particular boy's home (Kincora), or to the other five boys' homes, and the circumstances which led up to the problems. Asked if he believed it was an attempt to discredit his allegations Mr Wallace said: "I can't prove that, but when I asked a former colleague why he didn't speak out he told me: 'Look what happened to you'. Colin Wallace, who quit his job after trying to highlight the Kincora scandal, and refusing to take part in a smear campaign against leading politicians, has begun legal action against his former employer.Wallace was told what duties he was expected to carry out; and indeed it would appear that he had already been undertaking unattributable briefing activities of this kind, which may have included disinformation.

In his book, Inside Intelligence, former SIS officer Anthony Cavendish confirms that he knew Wallace and says that his story is "frightening and disquieting, but one which ties in with many events to which I have been privy".

To read this book in 2022 with the Brexit vote, the crash in Jeremy Corbin’s popularity and the anti-semitism report into the Labour Party, parallels begin to appear.
