While waiting at a train station, Mr. Jones (Albert Salmi) becomes convinced that another traveler, Mr. Bellfontaine (Robert H. Harris), is an escaped psycho killer -- and Bellfontaine arrives at the same conclusion about Jones. Their paranoia is fed by a policeman (Ken Clarke), who evidently thinks that either one of the men could be the killer. Sure enough, there's a criminal at large at the train station -- but his identity comes as quite a surprise. This was the final episode of Alfred Hitchcock Presents' second season. ~ Hal Erickson, Rovi
