The letterbox clatters and sitting on the mat is a piece of paper, in black and white, with everything needed to blow Anna's perfect life apart.
A baby scan photo.
Anna and Jon have been trying for a baby with no success, so after years of disappointment, this feels like a kick in the teeth.
Who sent it? And why?
Anna's thoughts fall on Grace - the keen young woman Jon hired at their printing business. Something about Grace isn't quite right. She asks too many questions and makes Anna nervous but she can't work out why.
And she can't deny she sees the way her husband looks at her.
All she knows is this baby scan might tear her marriage apart...
