Old Bailey, Lonsdale was charged with spying, along with associates Harry Houghton, Ethel Gee and Morris and Lona Cohen (Peter and Helen Kroger). At the time of the trial, British authorities were still unsure of his true identity. In March 1961, the defendants were found guilty, and Lonsdale received a 25-year sentence. He was to start his sentence at Winson Green Prison, Birmingham. From his single cell, he fraternised with some of the Great Train Robbers. In due course, the British and American security services managed to establish his true identity as Russian citizen Konon Molody. On 22 April 1964, he was exchanged in a spy-swap for Greville Wynne, a British businessman apprehended and convicted in Moscow for his contacts with Oleg Penkovsky. The prisoners were swapped at the Heerstraße Checkpoint in Berlin. Later life in Russia A year after his return to the Soviet Union he published a book Spy: Memoirs of Gordon Lonsdale with the author still maintaining he was born in Canada. Issued with the approval of the Soviet authorities, he also claimed Peter and Helen Kroger, convicted as members of the Portland Ring, were innocent. Molody died from a stroke on a mushroom picking expedition in a suburban forest in October 1970; at the age of 48. Konon's youth friend and retired KGB intelligence agent Leonid Kolosov co-wrote The Dead Season: End of the Legend. He maintained that Konon was healthy upon his return from the UK but began complaining about KGB doctors giving him injections against high blood pressure. Konon had headaches he never had before but the doctors said he should expect to "feel worse before he felt better". He is buried at the Donskoy Cemetery in Moscow next to Vilyam Genrikovich Fisher (aka Colonel Rudolf Abel). A 1968 film Dead Season was based on Molody's mission in the UK. where he personally advised Donatas Banionis who played him, and believed that resemblance between him and the actor was significant.
