Emeritus Prof Christopher MayRIP Len Deighton.
Deighton's working class spys in books such as the Ipcress File & Funeral in Berlin were a major shift in the literature of espionage...but for me, his best work was Bomber.
And the reason: my father pilot & Squadron Leader in Bomber Command during WW2, thought it was the best depiction of what he had gone through, he ever read & this from a man who refused for the most part to discuss his role in what he had subsequently concluded was a war crime.
