Sleepers West (1941)

 In Lloyd Nolan's second Micheal Shayne movie the detective is escorting a secret witness (Mary Beth Hughes) by train from Denver to San Fransico, this all relates to some unfinished business from his time on the police department. On the train Shayne encounters an old flame (Lynn Bari) and some people who would like to kill the witness. There is nothing special about what might be called the "mystery element" of the film, but there is some poignancy to a sub plot about would be lovers who meet on the train and the film is never more entertaining then when Shayne is messing with people. Getting the now endangered witness off the train by Ogden also becomes a plot point. So far this series remains solid. ***
