About the book: 2006 / Just yesterday, Basel Police Commissioner Peter Hunkeler did not imagine what the coming summer weeks would turn out for him. The holidays began, the city was empty, and those who did not leave had no intention of robbing, killing, or stealing. Quiet work, a beloved woman, weekends spent in nature - what else does a middle-aged policeman need? And here you go: Dr. Krista Erney is found dead in her office. Who's the killer? Patient, relative, lover, or maybe his own son?..
