Robert Harris, Enigma
Ballantine Books. 1996 (originally published 1995
The first 3/4 of Enigma is a good, taut novel set in Bletchley Park during World War II. The depiction of the deciphering process, and of the lives of the people there and in England generally, is solid and compelling. Then, in the last 100 pages, it tears your heart out. I can't, really say anything more than that. It is the best book I have read so far this year.
