From mysteryfile.com: When a young professor at the University of Washington (in what department I don’t think it’s ever said) is unjustly denied tenure. he’s forced to look for work in the real world. Luckily his Uncle Cosmo has just won the lottery, and he helps his nephew out.

With full custody of his auto-repair shop. It’s hardly the gold mine of opportunity he envisioned, as you can imagine, and when the body of his former department chairman is found on the premises, it turns into outright disaster.
