The semaphore of semis

摘要

THE SETTING for Robert Harris's thriller, "Enigma", is wartime Britain, where everything is rationed except for the rain. It follows Tom Jericho, a young prodigy stationed at Bletchley Park, the real-life centre of code-breaking operations, who is part of a team of cryptol-ogists trying to break the code used by Germany's armed forces. The work has frustration built in. Any progress can be undone if the enemy changes the code-which he will if he suspects that it has been cracked.
