Insurance agent-physician collects on policies of men murdered by a disfigured resident of the home for the blind where he acts as doctor-on-call.

A series of strange deaths takes place in London. All are accidents but the victims are single men with no family and they all have a link to a life insurance company run by the mysterious Dr. Orloff.—Col Needham <[email protected]>

In London, the Scotland Yard Detective Inspector Larry Holt is assigned to investigate a series of deaths apparently in accidents. However, a further inquiry shows that all the victims are men without family and insurance policy released by the insurance agent Dr. Feodor Orloff and the beneficiary is a home for the blind administrated by Prof. John Dearborn. When Henry Stuart is found drowned, his daughter Diana comes to London and helps Holt and his American partner Lieutenant O'Reilly in their investigation.—Claudio Carvalho, Rio de Janeiro, Brazil
