Fritz Honka quietly lived in Hamburg's red light district of St Pauli, picking up elderly prostitutes for the price of a glass of schnapps and a bed for the night. He began to lose his temper when the women declined his sexual perversions. He retaliated by strangling his victims. Disposing of the bodies presented a problem until he came up with the idea of dismembering them and storing the body parts in the roof space next to his flat. Had a freak house fire not crept up the building to expose his collection he might never have been caught. He claimed he had been instructed by London's Victorian Jack The Ripper to perform the murders. He was sectioned at a mental institute after being convicted of 1 murder and 4 manslaughters.

Bei den Löscharbeiten eines Hauses im Hamburger Rotlichtviertel macht die Feuerwehr im Sommer 1975 einen grausigen Fund: Leichenteile sind über den gesamten Dachstuhl verstreut. Die Opfer sind vier ältere Prostituierte. Schnell wird Hausbesitzer Fritz Honka als Mörder überführt.
