A review by nursenell
The Prodigal Son by Colleen McCullough

5.0

This is my favorite, to date, in this series about Detective Delmonico, set in a CT university town in 1969. Someone is using a very rare neurotoxin extracted from the blowfish to murder people. Delmonico's own niece is the biochemist who has extracted the toxin, and reports 6 ampules of it stolen from her lab. Her husband, another biochemist, is about to have a book published that is expected to be a best seller but not everyone thinks he wrote the book or is enthusiastic over its pending publication. And so the murders begin.
