Quality beekeeper Walter Eggert's corpse is found besides his hives, fatally poisoned with bee toxin by syringe. Prime suspect is competitor Manfred Bender, who mass-produces bordering on legal tolerances and also supplies honey grocer Benni Kastl. They had access to the poison, as well as his wife Josi, a pharmacist, who was jealous of his apparent affair with foxy 'bee therapist' Vera Fröhlich. Meanwhile the academy's lecture guest, crime author Thilo Wannek, uses the alias of newspaper law editor Peter Schmied to do some research, but arouses suspicion with unpleasant consequences.
