How the interval of suspense in which I was now condemned might have affected other men in my position, I cannot pretend to say. The influence of the two hours’ probation upon my temperament was simply this. I felt physically incapable of remaining still in any one place, and morally incapable of speaking to any one human being, until I had first heard all that Ezra Jennings had to say to me.

In this frame of mind, I not only abandoned my contemplated visit to Mrs. Ablewhite—I even shrank from encountering Gabriel Betteredge himself.

Returning to Frizinghall, I left a note for Betteredge, telling him that I had been unexpectedly called away for a few hours, but that he might certainly expect me to return towards three o’clock in the afternoon. I requested him, in the interval, to order his dinner at the usual hour, and to amuse himself as he pleased. He had, as I well knew, hosts of friends in Frizinghall; and he would be at no loss how to fill up his time until I returned to the hotel.

This done, I made the best of my way out of the town again, and roamed the lonely moorland country which surrounds Frizinghall, until my watch told me that it was time, at last, to return to Mr. Candy’s house.

I found Ezra Jennings ready and waiting for me.

He was sitting alone in a bare little room, which communicated by a glazed door with a surgery. Hideous coloured diagrams of the ravages of hideous diseases decorated the barren buff-coloured walls. A bookcase filled with dingy medical works, and ornamented at the top with a skull, in place of the customary bust; a large deal table copiously splashed with ink; wooden chairs of the sort that are seen in kitchens and cottages; a threadbare drugget in the middle of the floor; a sink of water, with a basin and waste-pipe roughly let into the wall, horribly suggestive of its connection with surgical operations—comprised the entire furniture of the room. The bees were humming among a few flowers placed in pots outside the window; the birds were singing in the garden, and the faint intermittent jingle of a tuneless piano in some neighbouring house forced itself now and again on the ear. In any other place, these everyday sounds might have spoken pleasantly of the everyday world outside. Here, they came in as intruders on a silence which nothing but human suffering had the privilege to disturb. I looked at the mahogany instrument case, and at the huge roll of lint, occupying places of their own on the bookshelves, and shuddered inwardly as I thought of the sounds, familiar and appropriate to the everyday use of Ezra Jennings’ room.

“I make no apology, Mr. Blake, for the place in which I am receiving you,” he said. “It is the only room in the house, at this hour of the day, in which we can feel quite sure of being left undisturbed. Here are my papers ready for you; and here are two books to which we may have occasion to refer, before we have done. Bring your chair to the table, and we shall be able to consult them together.”

I drew up to the table; and Ezra Jennings handed me his manuscript notes. They consisted of two large folio leaves of paper. One leaf contained writing which only covered the surface at intervals. The other presented writing, in red and black ink, which completely filled the page from top to bottom. In the irritated state of my curiosity, at that moment, I laid aside the second sheet of paper in despair.

“Have some mercy on me!” I said. “Tell me what I am to expect, before I attempt to read this.”

“Willingly, Mr. Blake! Do you mind my asking you one or two more questions?”

“Ask me anything you like!”

He looked at me with the sad smile on his lips, and the kindly interest in his soft brown eyes.

“You have already told me,” he said, “that you have never—to your knowledge—tasted opium in your life.”

“To my knowledge,” I repeated.

“You will understand directly why I speak with that reservation. Let us go on. You are not aware of ever having taken opium. At this time, last year, you were suffering from nervous irritation, and you slept wretchedly at night. On the night of the birthday, however, there was an exception to the rule—you slept soundly. Am I right, so far?”

“Quite right!”

“Can you assign any cause for the nervous suffering, and your want of sleep?”

“I can assign no cause. Old Betteredge made a guess at the cause, I remember. But that is hardly worth mentioning.”

“Pardon me. Anything is worth mentioning in such a case as this. Betteredge attributed your sleeplessness to something. To what?”

“To my leaving off smoking.”

“Had you been an habitual smoker?”

“Yes.”

“Did you leave off the habit suddenly?”

“Yes.”

“Betteredge was perfectly right, Mr. Blake. When smoking is a habit a man must have no common constitution who can leave it off suddenly without some temporary damage to his nervous system. Your sleepless nights are accounted for, to my mind. My next question refers to Mr. Candy. Do you remember having entered into anything like a dispute with him—at the birthday dinner, or afterwards—on the subject of his profession?”

The question instantly awakened one of my dormant remembrances in connection with the birthday festival. The foolish wrangle which took place, on that occasion, between Mr. Candy and myself, will be found described at much greater length than it deserves in the tenth chapter of Betteredge’s Narrative. The details there presented of the dispute—so little had I thought of it afterwards—entirely failed to recur to my memory. All that I could now recall, and all that I could tell Ezra Jennings was, that I had attacked the art of medicine at the dinner-table with sufficient rashness and sufficient pertinacity to put even Mr. Candy out of temper for the moment. I also remembered that Lady Verinder had interfered to stop the dispute, and that the little doctor and I had “made it up again,” as the children say, and had become as good friends as ever, before we shook hands that night.

“There is one thing more,” said Ezra Jennings, “which it is very important I should know. Had you any reason for feeling any special anxiety about the Diamond, at this time last year?”

“I had the strongest reasons for feeling anxiety about the Diamond. I knew it to be the object of a conspiracy; and I was warned to take measures for Miss Verinder’s protection, as the possessor of the stone.”

“Was the safety of the Diamond the subject of conversation between you and any other person, immediately before you retired to rest on the birthday night?”

“It was the subject of a conversation between Lady Verinder and her daughter——”

“Which took place in your hearing?”

“Yes.”

Ezra Jennings took up his notes from the table, and placed them in my hands.

“Mr. Blake,” he said, “if you read those notes now, by the light which my questions and your answers have thrown on them, you will make two astounding discoveries concerning yourself. You will find:—First, that you entered Miss Verinder’s sitting-room and took the Diamond, in a state of trance, produced by opium. Secondly, that the opium was given to you by Mr. Candy—without your own knowledge—as a practical refutation of the opinions which you had expressed to him at the birthday dinner.”

I sat with the papers in my hand completely stupefied.

“Try and forgive poor Mr. Candy,” said the assistant gently. “He has done dreadful mischief, I own; but he has done it innocently. If you will look at the notes, you will see that—but for his illness—he would have returned to Lady Verinder’s the morning after the party, and would have acknowledged the trick that he had played you. Miss Verinder would have heard of it, and Miss Verinder would have questioned him—and the truth which has laid hidden for a year would have been discovered in a day.”

I began to regain my self-possession. “Mr. Candy is beyond the reach of my resentment,” I said angrily. “But the trick that he played me is not the less an act of treachery, for all that. I may forgive, but I shall not forget it.”

“Every medical man commits that act of treachery, Mr. Blake, in the course of his practice. The ignorant distrust of opium (in England) is by no means confined to the lower and less cultivated classes. Every doctor in large practice finds himself, every now and then, obliged to deceive his patients, as Mr. Candy deceived you. I don’t defend the folly of playing you a trick under the circumstances. I only plead with you for a more accurate and more merciful construction of motives.”

“How was it done?” I asked. “Who gave me the laudanum, without my knowing it myself?”

“I am not able to tell you. Nothing relating to that part of the matter dropped from Mr. Candy’s lips, all through his illness. Perhaps your own memory may point to the person to be suspected.”

“No.”

“It is useless, in that case, to pursue the inquiry. The laudanum was secretly given to you in some way. Let us leave it there, and go on to matters of more immediate importance. Read my notes, if you can. Familiarise your mind with what has happened in the past. I have something very bold and very startling to propose to you, which relates to the future.”

Those last words roused me.

I looked at the papers, in the order in which Ezra Jennings had placed them in my hands. The paper which contained the smaller quantity of writing was the uppermost of the two. On this, the disconnected words, and fragments of sentences, which had dropped from Mr. Candy in his delirium, appeared as follows:

“... Mr. Franklin Blake ... and agreeable ... down a peg ... medicine ... confesses ... sleep at night ... tell him ... out of order ... medicine ... he tells me ... and groping in the dark mean one and the same thing ... all the company at the dinner-table ... I say ... groping after sleep ... nothing but medicine ... he says ... leading the blind ... know what it means ... witty ... a night’s rest in spite of his teeth ... wants sleep ... Lady Verinder’s medicine chest ... five-and-twenty minims ... without his knowing it ... tomorrow morning ... Well, Mr. Blake ... medicine today ... never ... without it ... out, Mr. Candy ... excellent ... without it ... down on him ... truth ... something besides ... excellent ... dose of laudanum, sir ... bed ... what ... medicine now.”

There, the first of the two sheets of paper came to an end. I handed it back to Ezra Jennings.

“That is what you heard at his bedside?” I said.

“Literally and exactly what I heard,” he answered—“except that the repetitions are not transferred here from my short-hand notes. He reiterated certain words and phrases a dozen times over, fifty times over, just as he attached more or less importance to the idea which they represented. The repetitions, in this sense, were of some assistance to me in putting together those fragments. Don’t suppose,” he added, pointing to the second sheet of paper, “that I claim to have reproduced the expressions which Mr. Candy himself would have used if he had been capable of speaking connectedly. I only say that I have penetrated through the obstacle of the disconnected expression, to the thought which was underlying it connectedly all the time. Judge for yourself.”

I turned to the second sheet of paper, which I now knew to be the key to the first.

Once more, Mr. Candy’s wanderings appeared, copied in black ink; the intervals between the phrases being filled up by Ezra Jennings in red ink. I reproduce the result here, in one plain form; the original language and the interpretation of it coming close enough together in these pages to be easily compared and verified.

“... Mr. Franklin Blake is clever and agreeable, but he wants taking down a peg when he talks of medicine. He confesses that he has been suffering from want of sleep at night. I tell him that his nerves are out of order, and that he ought to take medicine. He tells me that taking medicine and groping in the dark mean one and the same thing. This before all the company at the dinner-table. I say to him, you are groping after sleep, and nothing but medicine can help you to find it. He says to me, I have heard of the blind leading the blind, and now I know what it means. Witty—but I can give him a night’s rest in spite of his teeth. He really wants sleep; and Lady Verinder’s medicine chest is at my disposal. Give him five-and-twenty minims of laudanum tonight, without his knowing it; and then call tomorrow morning. ‘Well, Mr. Blake, will you try a little medicine today? You will never sleep without it.’—‘There you are out, Mr. Candy: I have had an excellent night’s rest without it.’ Then, come down on him with the truth! ‘You have had something besides an excellent night’s rest; you had a dose of laudanum, sir, before you went to bed. What do you say to the art of medicine, now?’”

Admiration of the ingenuity which had woven this smooth and finished texture out of the ravelled skein was naturally the first impression that I felt, on handing the manuscript back to Ezra Jennings. He modestly interrupted the first few words in which my sense of surprise expressed itself, by asking me if the conclusion which he had drawn from his notes was also the conclusion at which my own mind had arrived.

“Do you believe as I believe,” he said, “that you were acting under the influence of the laudanum in doing all that you did, on the night of Miss Verinder’s birthday, in Lady Verinder’s house?”

“I am too ignorant of the influence of laudanum to have an opinion of my own,” I answered. “I can only follow your opinion, and feel convinced that you are right.”

“Very well. The next question is this. You are convinced; and I am convinced—how are we to carry our conviction to the minds of other people?”

I pointed to the two manuscripts, lying on the table between us. Ezra Jennings shook his head.

“Useless, Mr. Blake! Quite useless, as they stand now for three unanswerable reasons. In the first place, those notes have been taken under circumstances entirely out of the experience of the mass of mankind. Against them, to begin with! In the second place, those notes represent a medical and metaphysical theory. Against them, once more! In the third place, those notes are of my making; there is nothing but my assertion to the contrary, to guarantee that they are not fabrications. Remember what I told you on the moor—and ask yourself what my assertion is worth. No! my notes have but one value, looking to the verdict of the world outside. Your innocence is to be vindicated; and they show how it can be done. We must put our conviction to the proof—and You are the man to prove it!”

“How?” I asked.

He leaned eagerly nearer to me across the table that divided us.

“Are you willing to try a bold experiment?”

“I will do anything to clear myself of the suspicion that rests on me now.”

“Will you submit to some personal inconvenience for a time?”

“To any inconvenience, no matter what it may be.”

“Will you be guided implicitly by my advice? It may expose you to the ridicule of fools; it may subject you to the remonstrances of friends whose opinions you are bound to respect.”

“Tell me what to do!” I broke out impatiently. “And, come what may, I’ll do it.”

“You shall do this, Mr. Blake,” he answered. “You shall steal the Diamond, unconsciously, for the second time, in the presence of witnesses whose testimony is beyond dispute.”

I started to my feet. I tried to speak. I could only look at him.

“I believe it can be done,” he went on. “And it shall be done—if you will only help me. Try to compose yourself—sit down, and hear what I have to say to you. You have resumed the habit of smoking; I have seen that for myself. How long have you resumed it.”

“For nearly a year.”

“Do you smoke more or less than you did?”

“More.”

“Will you give up the habit again? Suddenly, mind!—as you gave it up before.”

I began dimly to see his ............
