Suggestions that he was a homosexual, like his close friend and Soviet mole Guy Burgess, have never been proved. Harry Pollitt did not suspect Olga Gray, as he believed the traitor was Jack Murphy, one of the founders of the CPGB who had left the party over ideological issues.

But for the general or casual reader of history, there are titillating details of Liddell's relations with Anthony Blunt (later outed as a Soviet spy by Prime Minister Margaret Thatcher) and J.

They invented a power-driven lithographic printing press in 1853 and were believed to be the first in the UK to use steam-power for lithographic printing, notably of stamps: in 1886, under Joan’s brother Frank, the firm became ‘Ornamental Printers to the Queen’ and it survived until taken over in 1992. Certainly I worked for Richard Deacon (and co-authered a book with him) but nevertheless profoundly disagreed with some of his opinions.During the conflict, he was commissioned and served with the Royal Field Artillery and was awarded the Military Cross.

He died of heart failure aged 66 in 1958 at his home, 18 Richmond Court, Sloane Street, London, and was buried at Putney Vale Cemetery.This included setting up an arms shipment to Welsh nationalists sent by the Germans to prompt an uprising during a Nazi invasion. Despite her solid performance on the Krivitsky case, she was appointed supremo of the Regional Security Liaison Officers organisation in April 1940. I have always been puzzled by the treatment of Jane Archer, whom Liddell essentially started to move out at the end of 1939.

Mr Liddle must have been quite a force and, of course, lucky enough to have secretary (assistant) with the energy required. Though the Service knew that all were innocent, it was not until August 1982 that, thanks to intelligence from Oleg Gordievsky, it finally identified John Cairncross as the Fifth Man in the Ring of Five. This led in 1944 to the most extraordinary operation of all, when the German high command was fooled into thinking the main invasion of Europe would be around Calais rather than on the Normandy beaches.He had been friendly with Burgess for many years, and when Burgess went, so too did whatever chances Liddell still had for the top job.

Calypso Baring, daughter of Cecil Baring, 3rd Baron Revelstoke of Membland and of Maude Louise Lorillard, on 7 April 1926. His agent, Duško Popov, provided an Abwehr questionnaire suggesting that the Japanese Air Force planned to attack the United States at Pearl Harbor. One can see from this (I've no doubt it's all genuine) Mr Liddle could not be seen as a slouch - or his assistant for that matter. As I showed in an earlier posting, the Radio Security Service (RSS) was a separate unit, part of MI8. It took me a while to get through this: mostly the extended day and as consequence the additional hours in the garden, so come late evening the eyelids were drooping.These include Sir Dick White, Philby's nemesis in both MI5 and MI6, both of which White headed, and Peter Wright (of Spycatcher fame), one of the most avid of all mole-hunters. Joan Miller and Marjorie Amor were later to testify that these documents were then passed on to Duco del Monte, Assistant Naval Attaché at the Italian Embassy.
