took up the bottle which contained the opiate. The moment I saw it I opened my eyes. The bottle was very nearly empty! Even allowing for your giving him a teaspoonful at a time, it was absolutely impossible that he could have taken anything like the amount which was now gone. I then looked at the other bottle, and found that only one teaspoonful had been taken from it since you had charge of the case. You follow me, don't you? In the bottle which contained the alterative medicine there were still four doses; in the bottle which contained the opiate there was not more than a teaspoonful left. Beyond doubt what happened was this: you gave Aylmer, quite by mistake, two tablespoonfuls of the opiate – a dose which of course caused his death."
"You lie!" said Keith. "How dare you come to this room with that trumped-up story? I did not make a mistake with regard to the medicines. I was most careful, and I am prepared to swear in any court that I took two tablespoonfuls of the alterative medicine, which was in the larger bottle, and brought it to Aylmer between nine and ten o'clock that night."
"Swear it, then," said Strause, in a contemptuous voice, with a sneer on his lips, and a malicious light in his eyes which caused Keith to recoil from him as though he were a serpent – "swear it, and go right through with the whole thing. I have the bottles in my possession, and although there are no witnesses on either side, believe me it will be at best a nasty case for you. You were alone with the sick man – you gave him a fatal dose of the wrong medicine – you were remembered in the poor fellow's will to the somewhat unusual tune of ten thousand pounds. My fine fellow, you are in my power. Even supposing the murder is never brought home to you, your career as an officer in the North Essex Light Infantry is over."
As Strause said the last words he left the room, swaggering out with his usual gait.
Keith sank into a chair and pressed both his hands to his throbbing temples. Was this true?
CHAPTER VI.
A TRYING POSITION
When he had first got over his start of dismay, Gavon Keith's impulse was to defy Strause. He fully believed that the story was invented by Strause for his own purpose, and that poor Aylmer had not been given the wrong medicine. For what ends Strause should bring such a horrible accusation against him Keith could not at that moment guess. He thought matters over, however, with all the common-sense of which he was capable; and that evening, although he still felt weak and giddy, he went to see Major Strause at his quarters, and found that officer within.
"Ah," said Strause, "I thought you might call round. Well, what do you intend to do?"
"Nothing," replied Keith.
"You sit down under the accusation?"
Keith turned first red, then white.
"I do nothing of the sort," he said. "I deny your charge absolutely. I did not give the wrong medicine. I was particularly careful with regard to the medicines. It is true that poor Aylmer disliked the light – I therefore kept his sick-room in comparative darkness; but on the two occasions when I gave him medicines on that fatal night I took the bottles into the sitting-room. Between ten and eleven o'clock, as he was in considerable pain, I gave him a teaspoonful of the opiate. I distinctly recall the bottle and the words, 'One teaspoonful per dose.' He took it, and said it did him no good. He wanted me to give him a larger dose. This I refused. Soon afterwards the hour arrived when he was to take the other medicine. I took that bottle also into the sitting-room, and by the light from a gas jet poured out two tablespoonfuls – no more and no less. I brought the medicine back with me, and he drank it off. He seemed to find relief as he did so, and dropped off asleep immediately. What are you sneering at?"
"You give yourself away so splendidly," said Strause. "Aylmer would naturally feel relief from such a powerful opiate as you administered."
"I did not administer the opiate. I gave him two tablespoonfuls from the other bottle. It is, I suppose, within the region of possibility that the medicines may have been shifted into wrong bottles. For that I am not responsible. You will recollect, perhaps, the fact that you visited Aylmer in his room soon after nine o'clock that evening. You were there for a couple of minutes, and came out afterwards, telling me that he was asleep. I noted that you were quite two minutes in the room, by the little clock on the mantelpiece. I also observed that you walked about softly while there. If you bring this charge against me, I can but repeat what happened."
"And who will believe your word? you have no witnesses."
"Nor have you."
"I hold the bottles," said Strause, with another sneer.
Keith was silent for a minute or two.
"I see nothing for it," he said, "but to try and get an order to have the body exhumed, and thus have the case properly sifted."
Strause uttered an uneasy laugh. He walked to the window and looked out. Then he returned to Keith.
"You do not know, perhaps," he said, "that the effects of opium are very short-lived, and that long before now all traces of opium would have left the poor fellow's body."
"Let the case be brought openly to trial," was Keith's next remark.
"What! you would have yourself ruined, if not worse?"
"I would rather risk anything than put myself in your power."
As Keith spoke he rose and left the room without even saying good-bye to Strause. All that night he kept to his resolve to sift the matter thoroughly, and then repeated to himself, —
"Anything would be better than getting myself into Strause's power."
But the following morning he received letters from home which caused him to look upon the affair from a fresh point of view. His mother had been seriously ill; his cousin, as he always called Kitty Hepworth, wrote to him to say how nervous she had become. She also said that Mrs. Keith was troubled about money matters, having lately lost a large sum through the failure of an Australian bank. If there was any one on earth whom Keith worshipped, it was his widowed mother. Without a moment's delay he wrote to her to tell her of his unexpected legacy, and to ask her to put at least two thousand pounds of the money to her own credit. He further resolved not to give her anxiety by allowing the case of poor Aylmer's death to be investigated. In short, he deliberately, and without at all realizing what he was doing, put himself in the major's power.
For the first few weeks his enemy lay low, as the expression is. But soon he began to use the dangerous weapon which Keith had supplied him with. The poor fellow was blackmailed, and to a considerable extent. Strause now informed him that his delay in having the case investigated made it black against him.
"Had you acted when you first heard my suspicions, a jury might have been inclined to look leniently at the matter; but your reticence, and the very fact that you have used some of your legacy, would tell terribly against you."
Keith believed him, and that evening handed him five hundred pounds. From that moment his fate was sealed.
His face lost its youthfulness; he became haggard and worn. He hated himself for what he termed his cowardice. He was convinced in his own mind that if there was foul play in the matter Strause was at the bottom of it.
Meanwhile Strause was dropping hints in the regiment which bore fruit in a coldness towards Keith. Strause hinted that Keith held a secret, and that this secret had something to do with his lucky windfall, as it was termed. No one believed much what Strause said, but the evidence of their senses caused his brother officers to gaze at Keith in some surprise. Aylmer's name, mentioned on purpose, caused the man to start and change colour. The mention of the legacy was like touching a raw place. It was known that Aylmer had died very suddenly, that Keith had been with him at the last, and that there was no nurse. It was also known that Keith's legacy was an unexpectedly big one.
There came an evening when Strause and Keith dined together, and Strause, who wanted a very large sum of money from Keith, introduced a peculiar drug into his wine. This drug had a curious effect on the mind – stimulating it at first into unnatural activity, but weakening the judgment, and altogether causing the moral senses to remain in abeyance. It was an Indian drug, which Major Strause had learned the secret of from a native some time before. Its later effect was very much that of ordinary
