Len Deighton’s basic 1st novel, whose

protagonist is a nameless spy – later on christened Harry Palmer and made famous worldwide in the iconic 1960s film starring Michael Caine.

The Ipcress File was not just Len Deighton’s first novel, it had been his first bestseller and the book that broke the mould of thriller writing.

For the working class narrator, an apparently straightforward mission to find a missing biochemist becomes a trip to the heart of the dark and deadly conspiracy.

The film of The Ipcress Document gave Michael Caine one of his first and still most celebrated starring roles, as the novel itself has become a classic.
