Mr David Calcutt QC, the Master of Magdalene College Cambridge, has carried out a previous sensitive inquiry most satisfactorily and, if you agree, I would approach him to see if he would be willing to undertake this investigation. On 21 February 2019, Wallace wrote to the then Secretary of State for Northern Ireland, Karen Bradley MP, and provided her with documentary evidence that three of the official Inquiries into the abuses at Kincora had deliberately misled Parliament. Colin Wallace is a British former member of Army Intelligence in Northern Ireland and a psychological warfare specialist. In 1972, he was commissioned into the Ulster Defence Regiment and was immediately granted the acting rank of captain, although he also stayed in the ACF.

Later that year, Wallace was promoted to Senior Information Officer and, shortly afterwards, he wrote a lengthy memorandum to his superiors complaining that no action was being taken to stop the sexual abuse of children at the Kincora Home. With the instability of the west shoulder this year there was a section that took about 25 minutes to get through near the top of the icefall, covered in avalanche debris and the route often destroyed, we just had to power through and get out as quickly as possible. It was all part of Cecil King's "coup," which he was convinced would bring down the Labour Government and replace it with a coalition led by Lord Mountbatten.He also pointed out that the man was "a known homosexual" who blackmailed people into homosexual activities which he himself initiated. A few weeks later he was removed from his job on the grounds that his life "was in danger", and posted to an Army HQ in England. In the 1980s, however, Wallace produced some documents, including a series of handwritten notes by himself, which he claimed were taken at meetings with other members of the plot, including the Member of Parliament Airey Neave.

The inquiry undertaken by Calcutt confirmed that Wallace had, indeed, been working for the intelligence services during the 1970s and that his enforced resignation from the Ministry of Defence had been made on the basis of a false job description designed to conceal his covert role in psychological warfare. He then referred to a number of people as having been interviewed by British Army people for British military intelligence about McGrath and Kincora. The journalist Paul Foot, in his book 'Who framed Colin Wallace', suggested that Wallace may have been framed for the killing, possibly by renegade members of the security services in a bid to discredit his allegations that members of the intelligence community had attempted to rig the 1974 general election after which Harold Wilson came to power with a minority government.On 19 May 1976, The Daily Telegraph published a story under the headline: "Campaign in US to smear MPs". Wallace was later retried and freed, but Sussex Police are 'not looking for anyone else' in connection with this crime. 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. A government inquiry set up by Prime Minister Margaret Thatcher and undertaken by Sir David Calcutt QC confirmed that Wallace had, indeed, been working for the Intelligence Services during the 1970s and that his enforced resignation from the Ministry of Defence had been made on the basis of a false job description designed to conceal his covert role in psychological warfare. He worked in the British Army's Information Policy Unit in Northern Ireland between December 1971 and September 1974.
