While riding to Auburn, the narrator encounters Dr. Dorrimore and reluctantly gives him a ride to a hotel. He can't stand Dorrimore, who is a magician of sorts from Calcutta and who stupefied the narrator with his performance five years earlier. The narrator gives the Indian a ride but hopes his interaction with the man will be minimal. He discovers that Dorrimore is staying at the same hotel as him.
Shortly thereafter, the narrator's paramour unexpectedly arrives and he spends a few weeks thoroughly enjoying her company. He also reluctantly introduces her to Dorrimore. One night, a few weeks later, the narrator is sitting near a graveyard at night when he sees Dorrimore with his love. In a feat of jealousy, he springs forward, "bent upon murder", and awakens the next morning in his room with bruises on his body and throat.
When the narrator asks about his love, he finds out that she has never visited Auburn and that Dr. Dorrimore has left that morning. Later he reads about Dorrimore hypnotizing an entire audience in Baltimore by simply telling them what to see and hear. The magician also claims
that a peculiarly susceptible subject may be kept in the realm of the unreal for weeks, months, and even years, dominated by whatever delusions and hallucinations the operator may from time to time suggest.
