I‘m closing in on #52mysteries with this entry for Kentucky. Blue states are completed, green states are to be read with the books identified, and the gold state is a book from my shelf. The other two are DC and Puerto Rico, which are on different maps!
This was an interesting book. A little convoluted, definitely dated, but with good bones of a story. Not much sense of place. The author is now known (if at all) for being Sue Grafton‘s father.
