A superb thriller, and the first American film by German director Siodmak to enjoy any significant success. Alan Curtis plays an innocent man accused of murdering his wife, with Ella Raines, as his secretary, and Thomas Gomez, as an off-duty copy, engaging in a search for the man's female

alibi, a mysterious woman (Fay Helm) whose existence is denied by every witness. Adapted from a novel by Cornell Woolrich, with suitably Expressionistic camera angles and moody lighting.
