Summary Paleontologist Wolfram Landowsky, whose supervisor professor Wilhelm discovered a new flying dino species in Rumania, was skull-smashed in his temporary Rosenheim archaeology museum exposition office. Prime suspects are his Munich university assistant and lover Inka Silberstein, whom he dumped recently, as well as his wife Barbel, who pretends she found out about the adultery but expected it to blow over, as well as the preparator assistant he recommended fired for messing with a dino bone and even the professor, who 'delegated' too much without sharing credit. A HR failure forces chief Achziger this time to partner up himself with Bach, until Verena Danner agrees to take over. Christian Bach however cleverly delegates research to forensic doc Sandra Mai, which proves crucial as a suspiciously dumped last preserved edition of an outdated lexicon contains a clue for another motive.
