Watch out for the red herrings, I was wrong. And I am very rarely wrong in pre-1980's whodunits. Grabbing this to watch early Vincent Price I was pleasantly surprised at the quality of thriller that could be produced with the technology. For those of you looking for the technological aspects of movies the lighting and shadow work was excellent. That and the sound-tract adds a lot to the overall feel of the movie. An added plus was Darla from "Our Gang" adding a cute bit part of the movie. Comletely gore-less, this movie actually does as promised and delivers thrills without blood. Something most modern movies cannot pull off.

Problems with the movie - First it has a nasty habit of just dumping information on you instead of making the viewer gradually learn what happens. Second as most 1950's horror fare it does have a tendency to drag on. But both of these can be overcome by what some previous reviewers call a confusing plot. Sorry guys, if you know whodunit at the beginning of the movie it is not worth watching.
