Moriarty, Liane : The Husband's Secret

Your husband writes a letter to be opened after his death. Do you read it?
My Darling Cecilia
If you're reading this, then I've died . . .
Imagine your husband wrote you a letter, to be opened after his death. Imagine, too, that the letter contains his deepest, darkest secret – something so terrible it would destroy not just the life you built together, but the lives of others too. Imagine, then, that you stumble across that letter while your husband is still very much alive . . .

Cecilia Fitzpatrick achieved it all – she's an incredibly successful business woman, a pillar of her small community and a devoted wife and mother. Her life is as orderly and spotless as her home. But that letter is about to change everything, and not just for her: Rachel and Tess barely know Cecilia – or each other – but they too are about to feel the earth-shattering repercussions of her husband's devastating secret.
