Watching you - Michael Robotham

Marnie Logan often feels like she's being watched. Nothing she can quite put her finger on - a whisper of breath on the back of her neck, or a shadow in the corner of her eye - and now her life is frozen. Her husband Daniel has been missing for more than a year. Depressed and increasingly desperate, she seeks the help of clinical psychologist Joe O'Loughlin.

Joe is concerned by Marnie's reluctance to talk about the past, but then she discovers a book packed with pictures, interviews with friends, former teachers, old flames and workmates Daniel was preparing for Marnie's birthday. It was supposed to be a celebration of her life. But it's not the story anyone was expecting . . .
