One final hypnosis session reveals a key traumatic event in Holmes' childhood: his father murdered his mother for adultery and committed suicide afterwards. Moriarty was the lover of Holmes' mother, and as such was indirectly responsible for their deaths. From that point on, his onetime tutor became a dark and malignant figure in Holmes' subconscious. Freud and Watson conclude that Holmes, consciously unable to face the emotional ramifications of this event, has pushed them deep into his unconscious while finding outlets in fighting evil, pursuing justice, and many of his famous eccentricities, including his cocaine habit. However, they decide not to discuss these subjects with Holmes, believing that he would not accept them, and that it would needlessly complicate his recovery.
