It's a picture-perfect summer's day when Prof. Boerne's golf tournament in Grothenburg is suddenly interrupted by a dead man in a tuxedo. With the tournament victory firmly in mind, Boerne is briefly tempted to deny his profession and to assume that Dr. Raimund Strothoff, the Münster banker, killed himself. But bondage marks on one of the ankles cause Boerne to call Inspector Thiel. In the meantime, a trauma patient is missing in the nearby health clinic and - just arrived - Thiel learns that the night before the dead banker had a loud argument with a beautiful woman who is just leaving the premises. Drives there at the endperpetrator of it? On the spur of the moment, Thiel and Boerne take up the pursuit of the unknown, lose her and soon face another dead man.
The perpetrator, that is clear, was identical in both cases. A vendetta? With what motive? Where is the connection? And who else is on the list? A corpse, a day and a night later, behind Thiel and Boerne are the most adventurous 24 hours they have ever spent together. And the longest short journey of her life. Once across the Münsterland and back. From the summer idyll of the golf tournament to a dark world that is so far away, but ultimately only a few forks in the road.
