Harold Tromball and the Case of the Missing Train

Harold is a private detective that lives in Chicago, Illinois, during 1933. He has been sharing an office with his best friend, Rocky, who is a trial lawyer. Their office also shares a single secretary whose name is Mae, who makes the best coffee in all of Chicago-well, at least that is what the guys believe. Neither has ever married, and together the three of them go on an adventure to locate a missing girl that is engaged to a mysterious gentleman who keeps changing his name. Rocky and Mae are constantly playing practical jokes on Harold as he is chasing clue after clue. Can this girl be found? And if so, will it be in time?
