Murder on the Mullet Express

It is 1926 and the Florida land boom is in full swing. Army Nurse Cornelia Pettijohn takes leave to travel to Florida with her ancient uncle, who claims that he wants a warm winter home. When their car breaks down, they take the local train, the Mullet Express, into Homosassa. By the time they arrive though, a passenger is dying of poison. Uncle Percival's hidden agenda makes him the sheriff's prime suspect.
