For the Viennese, it might come as a surprise that tram conductors have emotions. The young tram driver Theo Ptak has fallen for one of his passengers, a young woman who gets in his tram car every morning. Then one day, she is kidnapped by two men, with Theo a horrified witness. Theo begs former detective Leopold Wallisch – also known as Lemming – for help. Lemming reluctantly begins his search and soon stumbles across a dead body. Yet he’s also trying to figure out how Kaspar and Pannonia are involved in the case; the two are stowed in the hold of an East Indiaman just after the end of the Thirty Years’ War sailing along Africa’s east coast.
