ISABELLA.
This discovery at once irritated, amazed and perplexed the major. That the handkerchief of Mrs. Dallas should be bound around the head of Jaggard was strange, but that it should be perfumed with the deadly scent which impregnated the devil-stick was stranger still. Had Mrs. Dallas found the wand of sleep? Had Mrs. Dallas perfumed the handkerchief with its cruel poison? Had Mrs. Dallas drugged or stupefied Jaggard on that fatal night by means of that saturated handkerchief? These were the vital questions which presented themselves to the puzzled major, and which he found himself unable to answer.
And here, at this point, the personality of Dr. Etwald intruded itself into the affair. It was Etwald who had bound up the wound with the handkerchief in question, and who, according to the housemaid, had forbidden its removal. The question was, had he received it from Mrs. Dallas, or had he found it on that night by the side of the insensible man. If the first, Mrs. Dallas must have perfumed it designedly with the poison, and Etwald, knowing that it was so impregnated, must have used it advisedly as a bandage. If the second, Mrs. Dallas must have been in the room on the night in question, and have used the handkerchief to render Jaggard insensible. And in either case, as the major very sensibly concluded, Mrs. Dallas must be in possession of the devil-stick. Otherwise, how could she have obtained the deadly scent?
"And the plain conclusion of the whole affair," soliloquized Jen, "is that Mrs. Dallas must have stolen the devil-stick, must have murdered Maurice, and must have drugged Jaggard for the purpose of completing her devilish work by stealing my poor boy's body. But her reason?"
That she did not desire Maurice for a son-in-law was an insufficient motive for the commission of a triple crime. She had declined to sanction the engagement; she had forbidden Maurice the house; and, assisted upon all points by social rules, she had ample power to prevent the match, which, as she averred, was distasteful to her. Why, then, with this power, should she jeopardize liberty and life by thieving the devil-stick and killing the man? In his perplexity, Jen sought out David and asked his opinion. The young lawyer gave a very decided verdict in favor of Mrs. Dallas.
"I don't believe Mrs. Dallas has anything to do with the matter," he said, in a decisive voice. "She had no motive to commit these three crimes, each one of which is more terrible than the other. Nor, major, do I think that she has nerve or brain enough to design or accomplish assassination or theft."
"But I assure you, David, the handkerchief is hers."
"Granted; but you forget that Isabella was in the room on that night. She might have dropped the handkerchief."
"Well," said Jen, after a pause, "that is not improbable. But the perfume?"
"Oh," replied David, with a shrug, "we know that the scent is an Ashantee preparation. Dido's grandmother came from Ashantee, so it is just probable that Dido herself, knowing the secret, might have prepared a dose of the poison."
