This is the third appearance in this space by Mark Thielman. The first two were somber tales featuring actual historical personages. The current entry is not like that, as you can probably guess from the title.
The narrator is a part-time private eye who makes most of his living dressed as a potato, promoting the cause at various supermarkets. He says the Potato Board calls him the "Spud Stud."
Lately he's been doing his thing at Uncle Bob's Natural Food Emporium, but someone murdered Charlie, the produce manager, who was dressed as, yup, an avocado. The deputy suspects our hero. His only ally is an actress dressed as Babs the Baguette.
No, not somber this time. But enjoyable.
