Start-up-founder Michael Novak falls to his death, badly belly-stabbed, from the co-working space room, just when detectives Ainfachnur and Hahn come question his colleague Novaks on another employee's recent murder. Despite the tropical heath, everybody is locked inside without air conditioning for 24 hours. Suspects include friend and already successful fellow Start-up-founder Andreas Hauser, Julia Bartsch, claims she only met Novak for occasional coffee, and Christian Heibl, whose innovative bio-products firm is hiding serious allergenic problems.
