When a ransom bid results in the death of a child, the police have only one lead – the old lady who witnessed the kidnapper using a public phone box. Though her recollection is vague, she volunteers to act as bait for the killer – telling the press that she had seen the kidnapper's face, she waits for him to attack...A compelling British noir boasting a gritty, powerful performance from Dan Duryea, Do You Know This Voice? is based on a story by noted crime/gothic horror writer Evelyn Berckman. It is featured here in a brand-new transfer from the original film elements in its as-exhibited theatrical aspect ratio.
