The Dark Eyes of London (U.S. title The Human Monster) is a 1939 British horror film produced by John Argyle and directed by Walter Summers, and starring Béla Lugosi, Hugh Williams, and Greta Gynt.

The film is about a scientist named Dr. Orloff who commits a series of murders for insurance money, while periodically disguising himself as the blind manager of a charity to further his scheme.

Scotland Yard begins finding bodies in the Thames River, all of them insured by Orloff with the Dearborn Home for the Blind as their sole beneficiary.

This charity Home, which Orloff sponsors and serves as its medical advisor, is located in a dilapidated former warehouse abutting the Thames.

One of the dead men has a daughter named Diane for whom Orloff obtains employment at the Home as seeing-person secretary to the soft-spoken, also blind, Dearborn.

Bela Lugosi adds much to the eerie atmosphere, and Hugh Williams as a keen young inspector is comfortably reassuring.

"[12] Variety wrote: "Too much is made of the scenes where the blind are shown at work, and the anti-climax is too heavily prolonged after the story apparently is concluded.
