For almost 40 years, the clever little roundish detective has been inspiring even the most reluctant readers to stick their nose into a book. Using the included "secret red foil", readers learn at the end of each case whether or not they have found the right solution. Although nobody would think that the clever little detective in Columbo look had it in him, he is able to react quick as a flash (does Karate) and solve even the most difficult cases by close observation and careful investigation. With esprit and a true sense of humour he always solves even the toughest criminal cases. His name says it all: Kugelblitz means ball lightening – round as a ball and quick as a lightening flash!

In 2022 the Kommissar Kugelblitz crime stories for children celebrate their 40th anniversary – and more than 4 million books have been sold to date.
