Valerie de Chavannes, a financier's daughter, summons Kayankaya to her villa in Frankfurt's diplomat's quarter and commissions him to find her missing sixteen-year-old daughter. 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 taste for adventure. Then another seemingly posh job turns up: a major publisher needs to protect a writer who has offended Islamist groups during the Frankfurt Book Fair. The two cases seem to be straightforward, but it goes all-wrong for Kayankaya, as it almost always does. Luckily, that's when he's at his best.
