JAY JAX, Mike Morris, and Anthony Mattola were three friends of the Great War. Jay was from New Jersey. Mike was from San Francisco. Tony was an Opera singer from Milan, Italy. After the war, each went their separate ways. Jay became a Woodbridge, New Jersey, cop. Mike was a cop in San Francisco, and Tony went back to the opera.

Eighteen years later, all three lives become intertwined. Jay moved to San Francisco after Mike offered him a job on the San Francisco Police Department. In 1932, Jay was seriously wounded during a shootout with a Canadian bootlegger. After a year convalescing, he became a Private Investigator. In June 1936, he was a witness to a suicide. Or was it? It will take Jay on a 3,956-mile train trip to find the answer.
