Dan Duryea stars in this unsavory British melodrama as a seedy kidnapper who accidentally kills his child victim. The police pretend to be unaware of the murder in hopes of capturing Duryea when he comes to collect the ransom. He wriggles out of this trap, then finds he must contend with a nosy neighbor (Isa Miranda) who seems to know more about him than she's letting on. Duryea schemes to poison the woman, but the plan boomerangs and his own wife dies instead. Outside of Dan Duryea's bravura performance, Do You Know This Voice? has zero entertainment value. ~ Hal Erickson, Rovi
