Excellent British Film Noir "3 Steps to the Gallows" follows American Sailor Scott Brady trying to visit and then just locate his brother while docked in London. Mary Castle as the lounge singer at the Gay Mask club gives this film an extraordinary aura. Her abbreviated performance of "There's No Way Out" paves the way for Brady to commence making contact with all of the characters involved in the plot. Pay attention - no one is above suspicion. Brady is more than a bit of a bull in a china shop but the rest of the cast is more subtly believable. This moves along at a good pace with no dead time. Worth seeking out.
