Case of the Great Train Robbery
Short PI Sean NMI Sean follows moldering money and a rusty revolver to murder, bedtrayal and a very cold case.
It doesn't matter how old the case is, when the dog finds a rusty revolver in the back yard, sean investigates. He finds a bag of swag, what was once a large stash of cash, some of it from the beginning of the 20th century.
Next thing Sean knows, some low-life attacks him with a length of gas pipe. Then a double murder, then there are cops from multiple jurisdictions galloping about. Shades of the 1930's! Ultimately the tracks lead the pint-sized detective to corruption, payoffs and answers to questions nearly one hundred years old.
