Alison Wilson for her two sons, and quoted in Crook's 2010 biography of Wilson. The Foreign Office documents included a 1943 file marked "The Case of the Egyptian Ambassador", an MI5 investigation into alleged espionage by ambassador Hassan Nachat Pasha and his staff in London from the beginning of the war. The documents reveal that the SIS/MI6 translator, presumably Wilson, was accused of embellishing translations of intercepted telephone calls to and from the Embassy. The agent investigating Wilson's translations, Alex Kellar, was later found to have been working for the KGB mole at MI5, Anthony Blunt. A report noted that the translator had faked a burglary at his flat and had been in serious trouble with the police. In one of the 1943 documents, MI5's Director General, Brigadier Sir David Petrie, states that the fact Wilson was no longer in the service was "...perhaps some small compensation for the amount of trouble to which his inventive mind has put us all. A fabricator, such as this man was, is a great public danger". Then-Chief of the Secret Intelligence Service, Sir Stewart Menzies, wrote: "I do not think it at all likely that we shall again have the bad luck to strike a man who combines a blameless record, first-rate linguistic abilities, remarkable gifts as a writer of fiction, and no sense of responsibility in using them!". Crook believes that Wilson could have been the victim of an attempt by Blunt to discredit MI6. Wilson may have faked the burglary to hide from Alison that he'd sold her jewellery to buy antibiotics to treat her post-natal infections. Alison Wilson reported in her memoirs that the police had not investigated the alleged burglary, nor did she recall that Wilson had been in trouble with the police as a result. Crook proposes that the British government took steps to prevent Wilson from "obtaining any kind of official or responsible employment" ever again, ending his publishing career and plunging him and his families into poverty. In 1942 Wilson told Alison that MI6 had decided he should go into the field as an agent. He said his subsequent misadventures, including being declared bankrupt, though never discharged, and being jailed for petty theft, were part of the cover he had to adopt for operational reasons. In January 1944 The Times of London carried a notice declaring Alex Wilson bankrupt. At this time, he lived in Hendon.
