Detective Inspector Andy Horton is on a sailing trip to France when he gets the news: Sergeant Cantelli’s nephew, Johnnie Oslow, is missing.

Johnnie was due to take part in the Cowes Week yacht races on the Isle of Wight, but he never turned up.

Horton’s boss isn’t interested. She thinks Johnnie must have gone off with a woman.

But then the charred remains of a body are discovered in a disused tunnel.

Is it Cantelli’s nephew?

The search for a missing person soon becomes a hunt for a ruthless killer. And this killer is just getting started.
