Crimes at the Dark House 1940

In this lurid melodrama, Tod Slaughter plays a villain who murders the wealthy Sir Percival Glyde in the gold fields of Australia and assumes his identity in order to inherit Glyde's estate in England. On arriving in England, "Sir Percival" schemes to marry an heiress for her money, and, with the connivance of the cunning Dr. Isidor Fosco, embarks on a killing spree of all who suspect him to be an imposter and would get in the way of his plans to stay Lord of the Manor.
