In all that had been said the evidence pointed against him, and him only, as the author of the crime; no hint of suspicion had been dropped against any other person; and the manner in which the crime had been committed indicated strongly that it was the act of a person actuated by jealousy, or animosity rather than that of a mere burglar. This view of the case was strongly brought out by the counsel for the prosecution. "The theory of the prosecution is," he said, "not that this unfortunate gentleman, while in the full possession of his senses, slew this lady, to whom he was nearly related, and for whom he had long cherished a sincere affection--the character you have heard given him by so many witnesses would certainly seem to show him to be a man incapable of such a crime. Our theory is that the latent taint of insanity in his blood--that insanity which, as you have heard from Dr. Arrowsmith and other witnesses, is hereditary in his ancestors on his mother's side, and has, before now, caused calamities, almost if not quite as serious as this--suddenly flamed out. We believe that, as has been shown by witnesses, he galloped away many miles over the country, but we believe that at last, wrought up to the highest pitch of frenzy, he returned, scaled the wall, opened the window, and murdered Miss Carne. You have heard that he was subject to moody fits, when he shunned all society; these fits, these wild rides you have heard of, are symptoms of a disordered mind. Perhaps had all gone happily with him, the malady would not have shown itself in a more serious form. "Unfortunately, as we know, there was sharp and sudden unhappiness--such unhappiness as tries the fibre even of the sanest men, and might well have struck a fatal blow to his mind. It is not because you see him now, calm and self-possessed, that you are to conclude that this theory is a mistaken one. Many, even the most dangerous madmen, have long intervals when, apparently, their sanity is as perfect as that of other people. Then suddenly, sometimes altogether without warning, a change takes place, and the quiet and self-possessed man becomes a dangerous lunatic--perhaps a murderer. "Such, gentlemen, is the theory of the prosecution. You will, of course, weigh it carefully in your minds, and it will be your duty, if you agree with it, to give expression to your opinion in your verdict."
