The Homicidal Diary

What strange compulsion drove an ordinarily gentle and cultured man, on one night of each week, to roam the city streets and commit a ghastly crime?

I am writing this account of my friend Jason Carse in the interests of both justice and psychiatry, and perhaps of demonology as well. There is no greater proof of what I relate than the sequence of murders which so recently shocked this city, the newspaper items regarding the crimes, and especially the official report of the alienists who examined Carse during his trial. I cannot expect to bring Doctor Carse back to life, for he was hanged until dead, but I do hope that this paper will offer new illumination on cases of criminal decapitation.

Justice and psychiatry are closely related, but it is difficult to recognize the judicial importance of so outré a subject as demonology. Yet I emphatically assert that the case of Jason Carse is irrevocably concerned with evil and dark lore such as mankind has not known since the Holy Inquisition.

One is naturally prejudiced against Carse, for even I myself, his lifelong acquaintance, was struck with repugnance when I first realized the nature of his activities, but his death on the gallows should foreclose biased reflection and permit the student to regard his case in a purely empirical light. As I am the only man in complete possession of the facts, it behooves me to give this astounding information to the world.

Jason Carse was a brilliant and respected criminologist, and at the time of his arrest he was recognized as one of the greatest students of the modern world, a fact which has made his case one of unparalleled notoriety. I was his roommate during the several years we spent in law school, and, although he shot to the pinnacle of his branch of jurisprudence while I was left to more prosaic routine, we never lost the contact which has now become so valuable. Our correspondence was frequent and regular since we were graduated, and I can say with justifiable pride that Carse respected my friendship as much as that of any other acquaintance, if not more. It was this intimacy with his personal life which has enabled me, as friend and confidant, to witness the revolting atavism which resulted in such outrageous crimes.

I obtained my first hazy acquaintance with the crimes three months ago when I received Carse's letter from Vienna. He had just discovered sensational evidence in a famous criminal case--one of recurrent human decapitation--and his consequent enthusiasm was so rabid that I was afraid the morbidity of such matters was beginning to pervert his senses. For several years I had become progressively aware of Carse's melancholic attitude, and I had often recommended that he take a vacation from criminal cases. His indefatigable enthusiasm for research was all against my advice, and he had gone relentlessly ahead to the tragic climax which my greatest fears could not have imagined. This letter from Vienna, so eager with indomitable il faut travailler, confirmed my suspicion that Carse had descended into the depressing rut of monomania.

When he returned to America shortly afterward I crossed the country to spend a few days with him, but he was so sickly and irritable that I could do nothing to cheer his spirits. He continually brooded over the case he had been investigating, and I should have known at that time there was a dangerous neurotic compulsion stirring in his subconscious mind.
