This is one of the earliest talkie whodunits; it still holds up quite well. It has a clever plot (sort of a precursor to Agatha Christie's "And Then There Were None"), some impressive tracking shots, and a striking séance climax. Dorothy Sebastian is hot; Boris Karloff (in a thankfully, in this case, minor role) is ridiculously hammy; the rest of the cast is fine, if not terribly distinctive. **1/2 out of 4.
