A series of gruesome murders on the Lincolnshire fens. An old enemy from the past. A deadly game of cat and mouse.

The peaceful little village of Saltern-le-Fen is buzzing with excitement. A film crew are in town, shooting a new TV police drama, Fen Division Five. But Detective Jackman receives a disturbing tip-off that something is wrong.

Detective Marie Evans meanwhile is looking forward to moving into her dream home. But there’s no time to celebrate. The naked body of a young man is found at the river’s edge. He’s been strangled, his skin massaged in expensive oil.

Two days later, another handsome young man is discovered in a shallow lake. His throat cut. He too is lathered in body oil.

At the same time, an arch enemy from the past emerges. A master manipulator who has his sights on Jackman and Evans. From behind the bars of his high security prison, he’s putting the finishing touches to a devastating revenge plan.

As they hunt a brutal killer, Jackman and Evans are themselves hunted in a deadly game of cat and mouse – and the stakes could not be higher.
