FROM THE SUNDAY TIMES BESTSELLING AUTHOR OF THE KIND WORTH KILLING

Two years ago, Martha didn't know that Alan existed. Now, they're married - it was easy to say yes to someone so sweet.

But when Martha thinks she sees Alan's mask slip, she starts to fear that the conferences he travels the country to attend might be a cover for something far more sinister.

As her research unearths a string of dead women, she enlists the help of Lily Kintner, an old friend from grad school. What Martha doesn't know is that Lily has a dark side of her own . . .

'The master of the gently perverse.'
