Mark Tartaglia of the London murder squad investigates a bizarre and brutal series of murders in this gripping thriller — the fourth in this bestselling series by Elena Forbes.

Detective Inspector Mark Tartaglia has spent the night in a west London hotel with a woman he has just met. When he is called to the same hotel the next morning to investigate a murder, he realizes it must have taken place while he was there. The investigation takes a horrifying turn when he recognizes the young female victim.

Still reeling from shock, he learns that another case he has been investigating — the body of a homeless man found in a burnt-out car — is also not what it seems. Tests reveal the corpse has been assembled from the body parts of four different people.

Under mounting pressure from the media and unsure where his loyalties lie, Tartaglia must solve this macabre puzzle before the Jigsaw Killer strikes again.
