Double Sunday Times bestseller Samantha Downing, author of My Lovely Wife and He Started It, is back with a deliciously twisted new novel...

Teddy Crutcher has won Teacher of the Year at the prestigious Belmont Academy. Everyone thinks he's brilliant. Only you know the truth.

They all smile when he tells us his wife couldn't be more proud - though if they stopped to think, they would realise no-one has seen her in a while.

They're impressed when he doesn't let anything distract him - even the tragic death of a school parent. Even when the whispers start, saying it was murder.

You're sure Teddy is hiding something about what happened that day. You're sure you can prove it.

You just didn't stop to think that when it comes to catching a killer, there's no place more dangerous than just one step behind...
