Synopsis:

Was his girl a killer?

Dick was engaged to Lesley but he didn't really know much about her. After all she had fired that shot, and then when he heard other things - about her past - and remembered that he was going to marry her...

Blood and violence rage through a quiet village in this lightning-swift story. Before long Dr. Gideon Fell appears on the scene, and this arch-enemy of crime pits his brain against a murderer so shrewd, so ruthless and so deadly that the sleepy little village becomes a nightmare town.
