SS:GB

SS-GB - Len Deighton

I am a big fan of Len Deighton, and this one is a departure from his typical stuff.  It is an alternate history, one in which the Germans have won WW2 and now rule over Britain.  The main character is a police detective on a case with dangerous political overtones.  I liked other novels where Germany has won the war, but this was one of the better ones.
