At times Derby would halt abruptly in his revelations, and I wondered whether Asenath could possibly have divined his speech at a distance and cut him off through some unknown sort of telepathic mesmerism—some power of the kind she had displayed at school. Certainly, she suspected that he told me things, for as the weeks passed she tried to stop his visits with words and glances of a most inexplicable potency. Only with difficulty could he get to see me, for although he would pretend to be going somewhere else, some invisible force would generally clog his motions or make him forget his destination for the time being. His visits usually came when Asenath was away—"away in her own body," as he once oddly put it: She always found out later—the servants watched his goings and comings—but evidently she thought it inexpedient to do anything drastic.
