Powers of Darkness by Fred M. White

Draycott braced himself for an effort. The comforting stimulus of the drug was still soothing and potent, so that the shock was not what it might have been. He was conscious that danger threatened him, but he was not afraid; he could have heard his death sentence with something like equanimity.

The man was an enemy. Blaydes was declaring war upon him. The ultimatum lost no force because it was delivered in a charming voice and with a pleasant smile. Who was this amiable old gentleman? He had come as the friend of Bassett, himself a harmless person upon whose money Moler had designs. Hitherto Draycott had regarded Blaydes with a certain good-natured contempt. His remarks about spirit-rapping had apparently been on a par with his intelligence. But he could not so readily explain away those hints as to the way in which Moler might have been attacked, nor the astonishing allusion to Oscar Lee.
