The day after her lavish wedding anniversary bash, Rosie Meyers gets a big surprise: Her nouveau riche husband Richie is leaving her for a sultry, sophisticated, size-six MBA. When he's found murdered in their exquisitely appointed kitchen, no one is surprised to find Rosie's prints all over the weapon.

The suburban English teacher is the prime suspect. The police's only suspect. And she knows she'll spend the rest of her life in the prison library unless she can unmask the real killer. Going on the lam into Manhattan, Rosie learns more about Richie than she ever wanted to know. And more about herself than she ever dreamed possible.
