This absorbing film noir was intended to be mostly of interest for its demonstration of the new science of forensics, as a Harvard Professor and a Cape Cod detective solve the murder of a young woman whose remains are discovered in the isolated sand dunes of the peninsular. Only by then she's a skeleton and the police have no other clues.
Bruce Bennett plays the academic and Ricardo Montalban the resolute cop. And they are fine and the investigation is actually fascinating as they build their case from nothing. But... the real bonus is the performances of a couple of the support cast. Jan Sterling as the seen-it-all peroxide floozy who gets killed...
...And particularly Elsa Lanchester as her duplicitous landlady. There's an efficient (Oscar nominated) script and a compelling story, but she really rips it up and is genuinely very funny though her dialogue isn't at all. She's one of Hollywood's greatest character actors and she elevates all her scenes.
John Sturges directs a spare, exciting B thriller. But there is also a sense of sadness for the dead girl and the jeopardy of the innocent suspect (Marshall Thompson). The locations in Boston and rural Massachusetts broke new ground for film noir and John Alton's photography is typically expressive. Maybe the mystery is, why isn't this better known?
