The question that must arise from the beginning,m and which turns this movie doubtful from the start, is how such an experienced and qualified detective as Lee J. Cobb could allow himself to be lead by such a woman to his own bad end? He must realize from the beginning that it must be impossible at length to get away with such a cover up. All the same, it's an interesting intrigue, the plot is formidable as Lee must perform a complicated double play which is bound to constantly get more difficult, but what saves the film is the tremendous finale. Hitchcock must have been inspired by this set-up at Fort Point under the great bridge with its fantastic opportunities for a thriller finale. There are many details adding to an excellent thriller, like her scarf blowing off in the end, the Italian family incident, the great introductory scene with its opening the door to any possible crime that only can be guessed at - and which leads to crime that no one wanted to commit.
Lee J. Cobb's foolery is questionable, but the film is great in spite of its foibles and should be worth restoring to its original quality indeed.
