A Chilling British Crime Thriller
A GRIPPING DCI KETT CRIME THRILLER FROM THE #1 BESTSELLER 'Fresh and ferocious' James Patterson

Whatever you do, don’t open the door…

When a severed foot is delivered to the unsuspecting residents of a student house in Norwich, DCI Kett begins one of the most gruesome investigations of its career.

And it’s not just a foot. More packages begin to appear at random on people’s doorsteps, all of them containing body parts that have been surgically removed and meticulously wrapped.

Kett is in a race against the clock to identify the victims and their killer, who shows no sign of stopping.

This monster isn’t just delivering corpses – they’re sending a message.

A riveting, pulse-pounding crime thriller perfect for fans of Ian Rankin, JD Kirk and Tim Weaver.
