After All These Years — Susan Isaacs

The day after her lavish 25th wedding anniversary bash, Rosie Meyers gets a big surprise: Her nouveau riche husband Richie is leaving her for a sultry, sophisticated size six MBA. So when he's found murdered on the Mexican tile floor in their kitchen (between the French six-burner and the English antique hutch), no one is surprised to find Rosie's prints all over the lethal weapon.

The forty-something English teacher is the prime suspect. The only suspect. But Rosie knows she didn't do it. Unfortunately, the police think otherwise and she'll spend the rest of her life stamping due dates in the prison library, unless she can unmask the real killer. So Rosie escapes the suburbs and goes on the lam into Manhattan. There she learns more about Richie's secrets than she ever wanted to know - and more about herself than she ever dreamed possible.
