Claire loves her husband David more than anything. His unexpected death shortly after returning from a business trip to Africa, where he managed development aid projects, throws her into a severe life crisis. Adding to the grief is a painful discovery: Claire finds out he was in a relationship with a high-end call girl. Without sparing herself, the widow now wants to know who the man really was with whom she unsuspectingly lived. Neither David's boss Hagedorn, a friend of the couple, nor his discreet assistant Michael support their investigation. Claire stumbles upon large bonus payments for David from his publicly listed employer, which is actually dedicated to fighting poverty, secret photos of a massacre of defenseless farmers in Africa and accusatory reports on the Internet about bloody deals. Not only do these discoveries make Claire shudder, but she always feels like she's being watched and strange things happen when she's alone. Now the woman, who has been under psychiatric treatment for years, begins to distrust everyone around her. Even herself. Claire suspects implications that terrify her beyond belief.

Kalt ist die Angst

The gas station attendant at a Mainz gas station was shot. This is the second assault in two weeks, but this time it's fatal. The only witness is the blind law student Rosa Münch, who still lives with her parents and longs for a life beyond the overprotective control of her father. Chief Inspector Ellen Berlinger and her partner Martin Rascher investigate the traces of the two perpetrators and follow the indications of the blind: The smell of an expensive perfume, the voices of suspects, the details heard and felt by Rosa at the crime scene. The commissioners want to put the vulnerable witness under police protection, but the young woman refuses. On the contrary, when another unknown young woman, whose voice sounds familiar, tries to contact Rosa, she keeps it to herself. The experienced investigators suspect that Rosa knows more than she says, and have to continue investigating without their support and resort to unusual methods to prevent further deaths.
