No, he's still alive

For the final few months of his service, Lee, who spoke fluent French, Italian and German, among other languages, was seconded to the Central Registry of War Criminals and Security Suspects.[63] Here, he was tasked with helping to track down Nazi war criminals.[64] Of his time with the organisation, Lee said: "We were given dossiers of what they'd done and told to find them, interrogate them as much as we could and hand them over to the appropriate authority".[64]
