A large chemical company in southern Germany is experiencing strange glitches in its data processing. A hacker has infiltrated the computer system and, for example, ordered 9,999 rhesus monkeys instead of 100, or had 500 marks transferred to all the secretaries. A prankster, perhaps, but still dangerous. CEO Korten hires private detective Selb from Mannheim to investigate the case.
