During a raid on a drug courier someone was killed by a single, extremely hard blow of a trained boxer. Dagmar Schnee appeared unexpectedly also at the crime scene because the events thwart their ongoing investigations at the club. First the junior boxer Antonio is under suspicion.
Small fry drug courier Timo was found, neck broken, outside 'professional' Vitali Zinger's ill-reputed nightclub and brothel, killed in a single masterly blow, so the police suspects local boxer Antonio 'Tiger' Jebke. The old coroner is convinced it's the signature of a former boxer and suspect, now Antonio's gym coach 'Lucky Bernd Litkowski, and actually Zinger's chief enforcer.—KGF Vissers
