An ordinary day. An ordinary street. A gruesome delivery waiting on the doorstep that's going to set off an spine-chilling chain of events...

Claire Beacham returns from a busy day at work to a parcel on her doorstep - no note, no label. As a politician, she's used to being suspicious of anonymous hate mail but today she's too tired to worry. She opens it, finding a gruesome surprise inside. A severed head falls to her kitchen floor; the rich, red drip of blood on her hands.

It is clear to Claire and those around her that this terrifying package is a message. But who sent it, and why?

It's Claire's first delivery - and won't be her last.

DI Finn cannot enjoy the gentle return to his role in the Murder Investigation Team of the Metropolitan Police that he planned. Someone is targeting Claire and with every message comes another casualty. With the clock ticking, DI Finn and DC Mattie Paulsen must wade through the depths of the murky political sphere before the bodies start piling up.
