"I don't see how anybody can have been in the room," he reflected, as he entered his house. "I saw that all was safe myself at midnight. The servants were abed, Sampson keeping vigil in the kitchen, and Jaggard sentry in the death-room. Moreover, I left the library door open, and the sound of footsteps stealing to the door of my poor lad would have wakened me out of the deepest sleep. Isabella's raps were light enough, yet I was up on the instant. No, I can't see myself that the devil who drugged the man could have been in the house; and yet the window opened from the inside. H'm! it is strange; very strange. I wish Jaggard were able to talk sensibly."
But Jaggard was far from the condition of connected thought or coherent words. He turned and tossed upon his poor bed with bright eyes, burning skin and babbling tongue. His head was swathed in bandages, and the housemaid who watched beside him had frequently to replace the clothes he tossed off in his violent movements. This nurse was a sickly, dark-eyed creature, who was strongly attached to Jaggard; and it was her love for him that made her proffer her services to look after him, and that chained her to his bedside. She reported to her master that Dr. Etwald had been in that morning, and was coming again in the afternoon, but that there was nothing to be done until the delirium had expended itself.
"Ay," thought Jen, as he stood by the bed, "or until the man dies. If he dies without regaining his senses, we will never know the truth."
He bent down to replace the bedclothes which the sick man had thrown off, and as he did so, a faint perfume, sickly and rich, struck his nostrils. It seemed to come from the bandages at the back of the head, and on bending down for a closer inspection, Jen saw that one of these--it was the merest corner which peeped out--was of finer linen than the rest. The fabric was cambric, and with a start which made the blood turn to ice in his veins, Jen realized that it was a woman's handkerchief--its delicacy and border-embroideries assured him of this.
"How came this here?" he asked the housemaid, pointing to the scrap of linen.
"Oh, that was on the first night, sir," she hastened to explain. "It was put on his head when in the room where he fell, sir. The doctor, sir, says as it ain't safe to take it away yet."
A curtain interposed between the head of the patient and the light of the window. This Jen drew aside, and lightly removed the outside wrappings of the wound. The housemaid looked on in horror, for she did not dare to prevent her master from meddling, yet she felt sure that he was doing wrong. But Jen was bent on making the discovery as to whom the handkerchief belonged; and in a few minutes he had the outside bandages removed, and saw the handkerchief discolored with dry blood lying over the wound. With deft fingers he lightly touched the four corners. In one of them were the initials "M. D."
"M. D.!" said the major to himself. "Margaret Dallas, the mother of Isabella. How did her handkerchief come into the room on that night? And the perfume?"
It struck his sense of smell with the belief that he had smelt it before. Nothing is so strong to awaken memory as odor, and in less than half a minute the mind of the major leaped back to where he had smelt it before. It was the perfume of the dried poison of the devil-stick.
