What Chief Inspector Frank Thiel and Professor Karl-Friedrich Boerne find in Münster this time is completely bizarre: the corpse of the lawyer Oskar Weintraub lies - completely pierced by the spear of an exotic warrior sculpture - in the middle of Doreen Prätorius' home. This house is like a museum of exotic art, and the circumstances of the death raise as many questions as the condition of the homeowner, who cannot remember anything - not even the cause of her own serious injuries. Now Doreen Prätorius is at the center of the murder investigation: How did this fragile-looking woman end up in this situation? Is she the victim of a tragic accident or perhaps a manipulative personality herself who crosses every limit in her definition of freedom?
