Alec DunBarton (aka The Singing Sleuth) and his wife, Paige, have been asked by the captain of the Pegasus to keep an eye on a group of archaeologists sailing on the ship's Panama Canal cruise. Alec didn't expect trouble. Boy, was he wrong!

On the second night of the cruise, Aaron Sloane, the former president of the Florida Archeology Organization, suddenly dies from fentanyl poisoning. None of his fellow archaeologists liked him. He was rude to everyone in his circle and cavalier about the death of his wife, Lena Sloane, who was bitten by a snake in the jungles of Panama five years earlier.

Secrets don't stay buried very long when Alec is hot on the trail. His suspects: include Annette Perkins, the persevering president of the FAO; Jennifer Bristow, the winsome museum curator; Victor Bristow, Jen's forbidding father; Michael Donovan, the rugged underwater archaeologist; Marshall Weissman, the talkative tech nerd; and Emily Irving, the angelic biblical archaeologist and captain's lover interest..

Find out who murdered Aaron Sloane and learn that archaeologists, like detectives, both share a desire to make the unknown known!
