Offbeat, atmospheric comedy-mystery about a murder prank that develops into a real murder. Despite the single setting (an archetypal old-dark-house, although it looks more like a castle from the outside), the camera is adequately mobile, like for example in a scene when it is travelling over and across a dinner table. The film is also distinctly pre-code, right down to the final scene where the Man accepts the Woman taking intellectual charge in their relationship (most post-code movies had the exact opposite message at the end). **1/2 out of 4.
