Retired physicist Dr. Gloria Lamerino has just returned to Revere, Massachusetts, when she learns of the death of Yolanda Fiore, a publicist recently fired from her job at the nuclear research labs in Revere. Young John Galigani, Yolanda'a former boyfriend and son of Gloria's Best friend Rose, is the number one suspect in the murder. In this mystery, Gloria tries to find Yolanda's real murderer and clear her friend's son.
Early in the story, a rather long list of potential suspects emerges, with motives ranging from revenge for a secret family feud, covering up some improprieties at the nuclear research facility, preventing the expansion of the town's library, to covering up a marital infidelity. The plot in this entry in Camille Minichino's Periodic Table mysteries is one of the best, with lots of clues offered to the reader. I really like the main characters in this series, the physicist Dr. Gloria and her boyfriend Matt Gennaro, a policeman on the Revere police force. Another enjoyable aspect of the story is how the author introduces the reader to scientific information about the element boron, which is a critical component in nuclear cooling systems.
If you're looking for a fun, intelligent mystery with great characters, you won't be disappointed here!
