Murder brings back memories ...

You're twelve years old. It's the summer holiday. You're playing in the woods with your two best friends. Something happens. Something terrible. And the other two are never seen again.

Twenty years on, Rob Ryan - the child who came back - is a detective in the Dublin police force. He's changed his name. No one knows about his past. Even he has no memory of what happened that day.

Then a little girl's body is found at the site of the old tragedy and Rob is drawn back into the mystery. For him and his DI partner, Cassie, every lead comes with its own sinister undercurrents. The victim's apparently normal family is hiding layers of secrets. Rob's own private enquiries are taking a toll on his mind.

And every trail leads inexorably back ... into the woods.
