All that glitters

The Lodger: A Story of the London Fog

(1927)

Very early Hitchcock, but he already knows how to make us sympathize with the creepy guy toward whom all signs of guilt point, while despising the ingénue's cop suitor; to keep us in suspense about guilt until late in the game; but to maintain our sympathy for the suspect even if he's guilty, the other guy being such an asshole ("When I've put a rope 'round the Avenger's neck, I'll put a ring 'round Daisy's finger").

Gorgeously shot as well.
