I spend a lot of time looking which fish is in the title. I finally found the answer, so it was one riddle less, but still I didn't know who was murdered and who was murderer. First, let's meet the characters:
Percival Pettijohn - travels from Kentucky to New Homosassa, Florida; wants to look at winter home, at least thats official version :P. He takes his camera everywhere, which sometimes gets him in trouble.
Cornelia Pettijohn - Percival's niece, travels with him to New Homosassa, couse she wants to have on eye on Percy
Theodore "Teddy" Lawless - companion of Cornelia (and Percival); she is an ex-army nurse; she loves to dance and can't imagine an evening without a glass of some alcohol (even if next morning she is dying C: )
I can honestly say that while reading "Murder on the Mullet Express" you can feel climate of that time :)
Our characters travel to New Homosassa, Florida, where there is a land sale. They are close to the town when Cornelia's car has an accident. Fortunately Peter Rowley, a land agent, helps them get to Ocala. Next day they travel by Mullet Express to this town, and are wittnesses to the fight of two passangers. Later they learn that both men are part of thier land sale party.
When one of the two men dies, police starts an investigation. They learn that almost everyone had a motive to kill him.
When the evidence points to Percival (at least that part of it that police seems to care about), Cornelia and Teddy have to find the real murderer before he (or she) completely destroy Percy's reputation.
Will they find the guilty and his/her motive? Read the book to find out!
