Valerie de Chavannes, a fiancier's daughter, asks private investigator Kemal Kayankaya to find her missing sixteen-year-old daughter Marieke. She is alleged to be with an older man who is posing as an artist.
To Kayankaya, it seems like a simple case: an upper class girl with a thirst for adventure.
Then another case turns up: The Maier Puplishing House believes it needs to protect author Malik Rashid from attacks by religious fanatics at the Frankfurt Book Fair.
The two cases seem to be straightforward, but together they lead to murder, rape and abduction, and even Kayankaya comes under suspicion of being a contract killer for hire.
