He sees you. But you don't see him... Dexter meets Rear Window. A new, edge-of-your-seat standalone thriller from Deborah Masson, award-winning author of the DI Eve Hunter series.

He's always watching you.

He sees everything. As a CCTV operator, Casey can monitor the streets of Aberdeen and keep people safe, all from the comfort of his chair.

He knows your secrets.

You are one of his favourite people to follow. He keeps an eye on you even in your most private moments, when you think you're alone.

But now he wants more.

There's a reason he's learnt your routine like the back of his hand. Casey wants revenge. And when you know as much as he does, it's easy to take advantage...
