... or did he? Ever? In 19th century England Edward Styles, a one-armed man, is being hung, for the murder of several women, with a large crowd watching. Who thinks watching an execution is entertainment anyways? But I digress. Styles is professing that he is innocent up to his death. He is buried in a lonely prison yard grave.

Fast forward twenty years and novelist James Rankin (Boris Karloff) is revisiting the Styles case to prove that if he had an attorney provided he would have likely been acquitted. He is trying to get this policy - the crown paying for an attorney for indigent defendants - to become law in England and use the Styles case as an example. After some digging - and some of that literally - he determines that the case against Styles was not only weak, but that the evidence points to a doctor who did the autopsy on Styles, was at his burial, and was the doctor present when the strangler killed all of his victims. He tries to find this man but his trail goes cold.

As for the rest of it, it has such a unique premise that I will say no more. Karloff is the best thing about this film, and the rest of the actors just seem like props around which he performs. It has great atmosphere, and I can really only say one bad thing about it. That one bad thing is that the scene at the bawdy music hall where The Strangler killed one of his victims is long and tedious. There actually is an entire musical singing number by one of the actresses and it just bored me. It would have been better if Karloff had just asked his questions, and maybe given you a feel for the place, and then have the movie just leave that place never to return.
