A vicious serial killer is holding the country to ransom, publicly — and gruesomely — murdering his victims.

When a man is burnt alive on a bonfire, it seems like a tragic Guy Fawkes Night accident. But with the discovery of a young couple on Valentine’s Day — each with an arrow through the heart — something more sinister becomes clear. A «calendar killer» is on the loose.

Detective Mark «Heck» Heckenburg is up against it. With a rising body count and the public’s eyes on him, Heck must find the killer before he executes more victims.

Because this killer has a plan. And nothing will stop him completing it.

A heart-stopping and grisly thriller that will enthral fans of Stuart MacBride and Katia Lief.
