Murder Divided by Three

Large print
Three detectives originally from Florida meet in David, Panamá. Clint Faraday is retired from the US and is living on the Comarca Ngobe Bugle with his wife and son and daughter.
CD Grimes is a billionaire private detective from Bonita Springs, Florida. He is with his wife and flew in his own jet to David at the invitation of his nutty musician, botanist, author friend, Dave, who works with Clint Faraday quite often and is also a close friend of the Indios.
Nick Storie is there with his wife just to see the country. He has a place on Martinique. He is a police homicide detective with Naples South Station.
(Theses are the three detective series I wrote and am writing)
Dave finds a murder case for them. They can try to solve it, each with his own method.
It seems to be an ordinary sort of thing.
At first.
