You can cover up the truth, but every murder leaves a trail.

The rain was relentless. It stung Ruth Prendergast’s face as she dashed towards her house, desperate to escape the cold and settle down for an early night. But upon entering her bedroom, she finds a man, lying on her bed–a knife buried in his chest.

When Detective Isabel Blood and her sergeant arrive on the scene, Ruth claims she has never laid eyes on the victim before. But with no sign of a break-in, how did the killer gain access to the house?

Then Ruth disappears, leaving Isabel and her team to fear the worst. Has their lead suspect escaped, or is Ruth in danger herself?

Forensic evidence at the crime scene is sparse, and it’s proving impossible for Isabel to make a breakthrough. With Ruth still missing, time is running out.

But how can you catch a killer that doesn’t leave a trace?

Uncover the mystery and solve the crime alongside Derbyshire’s best detective. This utterly gripping, unputdownable whodunit will have you hooked and reading long into the night. Perfect for fans Val McDermid, Elly Griffiths and ITV’s Vera,
