This low budget spy thriller about the murder of an agent who had retrieved some stolen blueprints which he hid in the luggage of an unsuspecting fellow train passenger just minutes before being murdered is quite entertaining and zips along at a good pace. This is due in no small part to the engaging lead actors, John Warwick and Jenny Laird. I had not heard of these actors before but evidently they went on to pretty solid television careers. Laird appeared in some TV shows (Morse and Midsomer Murders) that I am sure I've seen. The residential hotel setting was interesting and the minor subplot of the exchanges between the hotel manager and an irritating and daffy guest were amusing. Watching this is a pleasant way to spend 57 minutes.
