I wanted to like this more, but I couldn't. Two shifting narrators and I didn't like either one of them. Also the concept of a good person being psychologically coerced into an evil action by a sociopath has been done better. Specifically, I could not help but compare this novel unfavorably to James M. Cain's Double Indemnity which burns white hot and leaves the reader shaken and stunned. In Cain's brilliant noir masterpiece we are propelled, squirming and almost afraid to continue, through the anguished and paranoid thoughts of the protagonist and chilled by a villain as dark and psychopathic as they come. There is even a plot similarity in the investigator on the hunt but he is so much more effective in Cain's novel. Read Double Indemnity instead.
