Kismet - Jakob Arjouni

It all began with a favour. Kayankaya wanted to help out Romario, the owner of a small Brazilian restaurant, who had been threatened by extortionists. Then suddenly there were two bodies on the floor of Romario's restaurant, their faces caked in white powder. Kayankaya is troubled by these deaths and decides to find out who the men are, until he himself is pursued by a mysterious mafia organisation. It becomes clear that he is facing the most brutal and dangerous group of gangsters ever to run Frankfurt's station quarter.
