Happy Birthday, Turk!

A Turkish worker, Ahmed Hamul, is stabbed to death in Frankfurt's red-light district; certainly no reason for the local police to work overtime. Kemal Kayankaya, however has a different attitude. He was born in Turkey, raised in Germany and now working as a Private Investigator. He has first hand experience of resentment against foreigners and now Hamul's wife, Ilter, has hired Kayankaya to find out who murdered her husband.
