The star of this British (ahem) 'thriller' was Tod Slaughter, who specialized in extremely hammy, over-the-top Victorian-style melodramas. All of his movies are low-budget potboilers, and he always plays the same character: a moustache-twirling, hand-rubbing villain, leering at some innocent maiden and plotting how to get his mitts on her. This movie is very loosely based on Wilkie Collins' 'The Woman in White'. Slaughter plays a maniac who kills a man then impersonates him to get his inheritance, even going so far as to marry his childhood-affianced fiancee! He murders anyone who gets in his way, and the whole thing is over the top, round the bend, to the moon and never coming back.
