Bletchley Park in Milton Keynes, England, has recently been restored at great cost, and remains of abiding interest to the public. This was where the computer was born and the German Enigma code was broken during World War II. In this action-packed novel, Chief Wren Sally Evans is found murdered on the grounds of Bletchley Park. The year is 1941, and two police detectives are given the unenviable task of solving the crime that occurred in Britain’s most secure code-breaking establishment, a place where questions are not welcomed. “Druid” is a German spy for Himmler who is parachuted into England to authenticate the communications to Germany by Abwehr agents already embedded in England. But upon his arrival, his mission is changed. “Baron” is a Soviet spy working at Bletchley Park for the first secretary of the Soviet Embassy in London, and he knew Sally Evans. The climax plays out within the pastoral Buckinghamshire countryside. Who committed A Murder at Bletchley Park?
