Like peanuts, you cannot stop in the middle of one of Cain's books. An insurance salesman plans the perfect murder. This book was written in 1935, after Cain was famous for The Postman Always Rings Twice and Double Indemnity.
This book takes place back in the 30s and is interesting as it is narrated by a murderer, something rare. An insurance agent decides to help a woman kill her husband to collect on insurance. It has some interesting twists and I would certainly recommend it and wish I could find more audio books by this author.
