Killing for Keeps: DCI Kate Daniels, Book 5 (Unabridged‪)‬

They know he's coming. 

Two brothers from the same criminal family die within hours of each other, five miles apart, one on the edge of a Newcastle industrial estate, the other in a busy A&E department of a local hospital, unseen by the triage team. Both victims have suffered horrific injuries. Who wanted them dead? Will they kill again? Investigating these brutal and bloody killings leads DCI Kate Daniels to break some rules, putting her career as well as her life on the line.

As the body count rises in the worst torture case Northumbria Police has ever seen, the focus of the enquiry switches, first to Glasgow and then to Europe, ending in a confrontation with a dangerous offender hell-bent on revenge.
