In cross-examination the maid had denied having heard the least quarrelling between the sisters, and could not suggest any reason for her mistress having taken her own life. Lady Madeley, obviously deeply affected by the tragic death of her sister, had corroborated the evidence given by the maid; and distinguished surgeons and analysts had deposed the death to have been due to prussic acid, and that the same poison could be traced in the wine remaining in the glass. The coroner summed up, emphasising the evidence which had been given, and which, he remarked, pointed conclusively to suicide. Alluding to the fact that the body[24] was unclothed, the coroner added that he thought the jury would find therein ample justification for coming to the conclusion that the mind of the deceased had become unhinged. With such plain evidence of fact before them he assumed the jury would have no difficulty in arriving at a verdict. If the evidence of the maid had stood alone, they might well have had reason for some hesitation and might have wished to probe further into the matter for a motive to account sufficiently for self-destruction. But the maid had been for some years in the employment of a family, members of which had testified to the exemplary character she bore, and her evidence was in every way corroborated not only by Lady Madeley, but also by witnesses from the library in Bond Street, the livery stables, and the other places to which she had been sent by her mistress. There could be, therefore, not the smallest suspicion attaching to[25] the maid. As far as they were aware, the only other visitor Miss Alvarez had had that afternoon had been her sister, Lady Madeley. Now, the evidence of the maid had clearly established the fact that when she returned on the first occasion Lady Madeley had already gone, and the maid then saw her mistress alive and spoke to her. The only other alternative which remained was that during the second absence of the maid some unknown person had entered the flat and had administered the poison. That alternative could not be dismissed as an impossibility. Miss Alvarez was certainly alone in the flat at the time when this might have occurred, but there was much evidence which all tended to negative the likelihood of such an explanation being the correct one. For murder by an unknown person to be the explanation, motive, and a strong motive, became essential. Robbery was disproved by the fact[26] that nothing whatever had been removed from the flat, not even the purse which was found lying on the table by the bedside; nor the money, some six or seven pounds, which still remained in the purse. That disposed of any hypothetical
