The 39 steps

This is a movie about a gentleman who gets himself into the middle of a dangerous spy game trying to help a spy lady who eventually gets killed. Now this man is accused of the murder of this spy lady and then he is literally left with no one who would believe him. Throughout the movie this guy gets chased chased chased .. This movie has all the characteristics of a Hitchcockian classic and is supposed to have launched the career of Hitchcock. The whole plot unveils only in the final five minutes of the film. After seeing several of his movies I started feeling that maintaining the suspense till last minute is quite an art in itself.
