Fifth mystery featuring Kemal Kayankaya Valerie de Chavannes, a financier's daughter, summons private investigator Kemal Kayankaya to her villa in Frankfurt's diplomatic quarter and commissions him 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 Publishing House believes it needs to protect author Malik Rashid from attacks by religious fanatics at the Frankfurt Book Fair. Rashid has written a novel about, amongst other things, attitudes towards homosexuality in an Arabic country. Kayankaya is hired to be Rashid's bodyguard for three days. 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.
