is a novel by Robert Harris
, about Tom Jericho, a young mathematician trying to break the Germans' "Enigma
" ciphers during World War II
. It was adapted to film
in 2001. He is stationed in Bletchley Park
, the British cryptologist central office, and is worked to the point of exhaustion.
Apart from the plot, the book is notable for its grim descriptions of winter in a war-torn Britain.
The book, though fiction, is criticised by people who were at Bletchley Park as bearing little resemblance to the real wartime Bletchley Park.
