Private eye Michael Shayne must escort a special witness by train. It turns out to be more trouble than he bargained for. Fun entry in the Michael Shayne series. Lloyd Nolan's great, as usual. Lynn Bari is Shayne's ex, a lady reporter trying to snoop out a story. Clichéd character, sure, but Bari makes it work. Nice support from Edward Brophy, Don Costello, and Mary Beth Hughes. Ben Carter and Mantan Moreland provide comic relief. Lots of snappy patter in this one and a nice pace. I'm a sucker for trains so having most of this movie take place on one was a plus for me. All in all, it's one of the better Michael Shayne movies I've seen. Nothing extraordinary but a good B detective flick.
