this be a rather pedestrian version of the agatha christie short story thriller ( philomel cottage ) . of course and the original short story confine itself to the time the couple spend on their honeymoon and although the subsequent adapt theater play expand on the plot . sylvia sidney come off a a kind of betty davis type with a distract edge to her delivery . john hodiak performance start off with subtlety but towards the end it deteriorate into melodrama . i agree with another reviewer that i couldn not help think that this would have get a much well treatment from alfred hitchcock . the plot development be implausible at time . although the beginning be cogent and mood setting and i be disappoint by the lack of subtlety in the end and which differ from the christie end . the story should have be about the psychology of predator and prey and but that aspect be mute . i have not read the theater play and so i do not know how it end compare to the wonderful christie end .
