Len Deighton Len Deighton Leonard Cyril Deighton (; born 18 February 1929), known as Len Deighton, is a British author. Deighton is considered one of the top three spy novelists of his time (along with Ian Fleming and John le Carré). In addition he is a highly acclaimed military historian, cookery writer, and graphic artist. "The IPCRESS File" (1962), his first novel, was an instant bestseller and broke the mould of thriller writing. "The Sunday Times" called him "the poet of the spy story". Deighton’s first protagonist – a nameless spy christened Harry Palmer in the films – was made famous worldwide
The IPCRESS File Deighton's mother cooked for Wolkoff's dinner parties and he said that he "vividly" remembered when British MI5 agents came to arrest her: "The experience was a major factor in my decision to write a spy story at my first attempt at fiction." The plot involves mind control, the acronym IPCRESS of the title standing for "Induction of Psycho-neuroses by Conditioned Reflex under Stress". The brainwashing is similar to a shock technique called psychic driving pioneered by Donald Ewen Cameron in the 1950s, originally on unwitting mental hospital patients, which was used and funded by the Central Intelligence Agency's secret MKULTRA
