Detective Aidan Waits is in trouble.

After a career-ending mistake, he's forced into a nightmare undercover operation that his superiors don't expect him to survive.

Isabelle Rossiter has run away again.

When the teenage daughter of a prominent MP joins Zain Carver, the enigmatic criminal who Waits is investigating, everything changes.

A single mother, missing for a decade.

Carver is a mesmerising figure who lures young women into his orbit - young women who have a bad habit of disappearing. Soon Waits is cut loose by the police, stalked by an unseen killer and dangerously attracted to the wrong woman.

How can he save the girl, when he can't even save himself?
