This is a very well staged murder mystery; the timings of movement throughout the fog-bound house riddled with secret passages are as precise as a ballet; and that helps keep the pace of it flowing along quite well. It needs to be, the dialogue is really quite poor and overall it's a waste of the talents of George Zucco and Lionel Atwill who don't really get much opportunity to get their teeth into the story at all. The story, well that's about a recently released inventor who invites a group of erstwhile business colleagues to his country house to avenge himself on those who he thinks were responsbile for his wrongful imprisonment. It's eerily enough photographed, but just goes on for too long without enough actually happening. I did like the ending though!
