How well do you know your husband? Cecilia Fitzpatrick, devoted mother, successful Tupperware business owner and efficient P&C President, has found a letter from her husband: 'For my wife, Cecilia Fitzpatrick, to be opened only in the event of my death.' But Cecilia's husband isn't dead, he's on a business trip. And when she questions him about it on the phone, Cecilia senses something she hasn't experienced before: John-Paul is lying. What happens next changes Cecilia's formerly blissful suburban existence forever, and the consequences will be life-changing for the most unexpected people.
