My Lovely Wife by Samantha Downing

A game twisted perhaps, but a way to keep their marriage alive. He finds them, she kills them. As the game gets more dangerous and closer to home affecting their children, Millicent and her husband begin to find themselves cornered. Their plan might be unraveling but will they get caught? This is one of those books where you think you know where it is going - these people are crazy and you might feel a little sorry for one of them and then BAM - the ending hits you full in the face. Taunt and very disturbing, this debut makes you hope you don't have those kinds of people for neighbors. Fans of all the twisted crime thrillers will eat this up.
