"You did nothing." Christine Steinmeyer thought the suicide note she found in her mailbox on Christmas Eve wasn't meant for her. But the man calling in to her radio show seems convinced otherwise. "You let her die..." The note and the call are only the beginning. Bit by bit, her life is progressively turned upside down: someone is trying to destroy her. But who among her friends and family can hate her that much? And why? Commandant Martin Servaz is on leave in a clinic for depressed cops, haunted by the latest crime committed by his nemesis, serial killer Julian Hirtmann. Then he receives a key card to a hotel room - the room where an artist committed suicide a year earlier. He soon realises that the key opens up a most intriguing mystery. Could someone really be cruelly, consciously driving women to kill themselves? Both he and Christine are about to find out...but it may already be too late.
