I have to be honest; I'm not at all sure what I think of this book.

We start out with a brutal familial murder in Minnesota: mother, father, baby, and cat are all dead. One son, Richard, has a giant cut on his leg; the other son, Dylan, is unharmed ... but covered in blood and holding an axe. It seems fairly obvious that he's the culprit.

Then, we have Polly Deschamps, who literally escapes an abusive childhood by running away to New Orleans. As an adult, she meets architect Marshall Marchand, and marries him after a whirlwind courtship. They share a duplex with Marshall's brother, Danny.

It's as plain as the nose on your face that Marshall and Danny are Dylan and Richard ... but which one is which (view spoiler) is not immediately clear. By the end of the book, we see the real story much more clearly.

Obviously, it's a page turner. I finished it over only a couple of nights. However, it was such a creepy look at the inside of sociopathy that I would be hard-pressed to say I enjoyed it. Hence, the three star rating.
