Book tip: Kellermänner play their part in a motorcycle thriller

There are products whose name stands for an entire segment: ‘Tempos’ are such an example, you could also say handkerchiefs. There are many adhesive tapes, but ‘Tesa’ also describes the whole segment... Indicators are often referred to as ‘Kellermänner’. No wonder, because the Aachen-based company virtually invented the genre of compact, high-quality, and shapely LED turn signals.

Now you can emphasize this as a company again and again, fits well into marketing. But it's even better to hear it from partners and customers. However, it becomes iconic when one's own products find their way into popular culture.


"That's good... was certainly expensive, your Harley ... the whole conversion ... Fender, Ape, Kellermänner, lowered... I nodded appreciatively, that was jargon and pure knowledge."

Kellermann turn signals and Harley Davidson motorcycles – they have belonged together for decades. The bikes from Milwaukee are often refined with Atto, Bullet, BL 2000 and other lights from Aachen. But who has turned this into a thriller?

None other than the author Michael Boenke, who after publishing cooking, school and children's books also made his crime debut with the Upper Swabian crime novel "Gott'sacker" in 2010. In the meantime, a whole series has been created.

A hot summer in Upper Swabia. Daniel Bönle, master of life and jack-of-all-trades in the parish of a village of 800 inhabitants on the edge of the Pfrunger-Burgweiler Ried, only wants to take a relaxed ride with his Harley Davidson when he comes across a corpse in a dilapidated chapel. In the skull is a cast-iron cross. The fear goes around in the village, because a short time later a shepherd dog, half buried and with a cross in its mouth, is discovered.

Michael Boenke was born in Sigmaringen in 1958 and now lives in Bad Saulgau in Upper Swabia. He studied German and Catholic theology. Since 2002 he has been working at the Institute for Vocational Religious Education at the University of Tübingen.
