a good solid piece of british movie making of it period . no classic but watchable . in the hand of a director like hitchcock and and there be some very hitchcockian theme here and this material would have make a minor classic . the former concentration camp doctor comeuppance ( he be gas in the hold of a ship be fumigate ) be wonderfully ironic . the dvd watch be part of a 50 movie boxset from mill creek call nightmare world and the transfer be far from good . the image be fuzzy and break up from time to time towards the end and and and somehow and presumably to save space on the disc and the frame have be crop on all four side . this be especially apparent during the opening credit and in a scene on a train where the evil doctor and a padre be seat facing each other in a carriage have a conversation all we see be their nose peep out from the side of the frame .
