She stared, paled, and finally began to tremble, not, as I now believe, at the insinuation latent in my words, but at the doubts which my question aroused in her own breast. “Did I?” she asked; then with a burst of candour which seemed inseparable from her nature, she continued: “Why do I try to mislead you or deceive myself? I did give a shriek just before the alarm was raised next door; but it was not from any knowledge I had of a crime having been committed, but because I unexpectedly saw before me my husband whom I supposed to be on his way to Poughkeepsie. He was looking very pale and strange, and for a moment I thought I stood face to face with his ghost. But he soon explained his appearance by saying that he had fallen from the train and had only been saved by a miracle from being dismembered; and I was just bemoaning his mishap and trying to calm him and myself, when that terrible shout was heard next door of ‘Murder! murder!’ Coming so soon after the shock he had himself experienced, it quite unnerved him, and I think we can date his mental disturbance from that moment. For he began immediately to take a morbid interest in the affair next door, though it was weeks, if not months, before he let a word fall of the nature of those you have just heard. Indeed it was not till I repeated to him some of the expressions he was continually letting fall in his sleep, that he commenced to accuse himself of crime and talk of retribution.” “You say that your husband frightened you on that night by appearing suddenly at the door when you thought him on his way to Poughkeepsie. Is Dr. Zabriskie in the habit of thus going and coming alone at an hour so late as this must have been?” “You forget that to the blind, night is less full of perils than the day. Often and often has my husband found his way to his patients’ houses alone after midnight; but on this especial evening he had Leonard with him. Leonard was his chauffeur, and always accompanied him when he went any distance.” “Well, then,” said I, “all we have to do is to summon Leonard and hear what he has to say concerning this affair. He will surely know whether or not his master went into the house next door.” “Leonard has left us,” she said. “Dr. Zabriskie has another chauffeur now. Besides (I have nothing to conceal from you), Leonard was not with him when he returned to the house that evening or the doctor would not have been without his portmanteau till the next day. Something--I have never known what--caused them to separate, and that is why I have no answer to give the doctor when he accuses himself of committing a deed that night so wholly out of keeping with every other act of his life.” “And have you never asked Leonard why they separated and why he allowed his master to come home alone after the shock he had received at the station?” “I did not know there was any reason for my doing so till long after he had left us.” “And when did he leave?”
