On Cold Ground

One snowy evening, a scream rings out from Lincoln Cathedral, and Detective Karen Hart is the first officer to reach it. Inside the chapel she finds a murdered man with a bloody cross cut into his forehead. The grisly death leaves the tight-knit local community reeling. A letter from the killer, signed 'The Cleanser', warns that this brutal murder is only the start.

As the ritual killings threaten to continue, Hart must uncover the killer's twisted reason before more victims fall. Her early leads collapse, and she begins to suspect a whispered conspiracy inside the police force, especially after a hostile new officer joins the investigation. She has to consider whether the answer lies closer to home than she wants to believe.

Hart is also struggling with her own private losses, still grieving the deaths of her husband and daughter. With this case the hardest of her career, she gets nearer to a dangerous truth than ever before. Can she assemble the pieces before the killer stops her?
