Late one night, a man calls the local emergency line. He's in a cemetery, and he's just discovered a freshly dug grave marked with a wooden cross bearing his name. The dispatcher thinks it's the ravings of a drunk - until the police find the man's body the next day.

What seemed like a morbid prank soon becomes a living nightmare for Berlin detective Jan Tommen. Recently reinstated to the force after a harrowing case's tragic conclusion, Jan enlists his friends - debt collector Chandu, hacker Max, and medical examiner Zoe - to help. Yet the unconventional team can't get any closer to finding the killer, and new open graves keep turning up, each with a promise of murder. Can they find the cunning killer before the deadly predictions are fulfilled?

From Alexander Hartung, author of Until the Debt Is Paid, comes another heart-stopping installment of the Jan Tommen Investigation series.
