The Husband's Secret - Liane Moriarty

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.
