“Hitchcock gets jubilantly to work on this very raw stuff, expressing with clever conjunction of shots, with superimposition, double exposure, dissolves, the moving camera, and all his bag of technical tricks, the feelings of loneliness, bitterness, and nausea which his characters might be expected to enjoy; he even tries to give the thing symbolic weight by sending his hero to perdition down the moving staircase of a tube station and the descending shaft of a mansion flat lift. I have never seen such an interesting, production of rubbish nor a clever film which deserved quite so little praise.”
