Eberhard Winkler is Rosenheim's first bee venom murder victim. He was allergic, the killer hid a dozen bees in his pillow, not fatal to a normal person, and he was forcibly prevented from taking his histamine medicine at hand, as blues attest. Suspects in the know of his allergy include ex wife Cornelia, dumped after adultery, and her partner, beekeeping farmer Horst Göbel, and Winkler's business partner Ewald Reuter, who now inherits their joint yacht business, where accountant Ortmann finds 'fake books' to cover up massive price fraud. She also inspires chief Achziger to give the detective economy driving lessons, which turns out badly with Lindt and Corbinian as semi-amused passengers.
