Det här låter som Lovecrafts historia med den skrymmande titeln " He ".
The narrator has recently moved to New York and encounters a stranger in historic clothing. The stranger offers to show the city's "secrets" to the narrator and reveals that he has learned a magical means to travel through time from Native Americans that he poisoned afterwards. The narrator is horrified by this and the visions of other times the stranger shows him. When he cries out in fear, this awakens the spirits of the murdered natives who then appear and kill the wizard.
