Again that phrase--"somebody else acting in me." Greatly impressed, Doctor Janet threw her into deep hypnosis. Now, an unexpected and most pathetic passage of personal history came to light. A year before, Marcelle had had a secret love affair, her lover had deserted her, she had determined to commit suicide. Failing to do this, she had, none the less--overwhelmed by the shock of the desertion, and giving herself wholly to grief and chagrin, which she felt obliged to allow no one to perceive--gradually passed into a dissociated, dreamlike state, in which she subconsciously pictured herself to herself either as no longer existing or as about to perish. Hence her "aboulia," hence the "somebody else acting in me," hence the refusal to take food. To Doctor Janet the situation was now almost as clear as the light of day--so, likewise, was the course which he would need to follow to restore the sufferer to her "real self," and rid her of all disease symptoms. The dissociation, to put it briefly, had in this case been so complete as to cause an actual disruption of the sense of personality. Nor is this malady of "loss of personality" as rare as one might be tempted to think. I could mention many cases not unlike that of Marcelle's, and some far surpassing it in astounding developments. There is, for example, the singular case of BCA. But this is so remarkable, so weirdly fascinating, and so instructive that it deserves to be treated, as I shall treat it in the next chapter, entirely by itself. CHAPTER VIII THE SINGULAR CASE OF BCA During his long career as a specialist in the treatment of nervous and mental diseases, Doctor Morton Prince, the celebrated Boston psychopathologist, has been called upon to deal with many puzzling human riddles, and to solve mysteries which, in their way, have been quite as complicated and baffling as any that ever taxed the ingenuity of that most ingenious of story-book detectives, Mr. Sherlock Holmes. In fact, some of the problems laid before the New England specialist surpass even the most astonishing of the adventures of Sherlock Holmes, thus proving once more that truth is stranger than fiction. This particularly applies to the BCA affair. In the beginning, however, there was nothing in the BCA affair to suggest to Doctor Prince that it had features which would test to the utmost his psychopathological skill. It opened in a prosaic, matter-of-fact way, with the arrival at his office of a young woman who wished to be treated for what she described as a "nervous breakdown." The story she told was a sad one, but he had heard many quite like it before, and it did not impress him as involving anything out of the ordinary.
