King of the Witches

"In the early 1930s the parapsychologist Wagner uses his telepathic sister to psychically uncover the presence of a nearby medium. This shadowy individual, named Orwicz, is amazingly powerful, simultaneously controlling several people who under his influence do things against their will–and immediately lose all memory of what they did.
One day the young Nazi sympathizer Krank and his police investigator superior Selin investigate Orwicz’s house. There’s no sign of Orwicz, but Krank and Selin discover that a number of the house’s previous residents were brutally murdered and, even more startling, that Orwicz himself died 30 years earlier. They determine that Orwicz has achieved immortality of a sort by projecting his consciousness into other peoples’ bodies, and pay a visit to Wagner to inquire how they might stop Orwicz.
The three conclude that the best way to take down Orwicz is through a SCANNERS-like psychic duel between him and another equally powerful medium. But where to find such a person? And how can they stop Orwicz’s psychically controlled subjects from battling Krank, Selin and Wagner through seduction, murder or worse?"
