Clearly, the pungent smell of the creosote rose high above all other contending scents.
“Do not imagine,” said Holmes, “that I depend for my success in this case upon the mere chance of one of these fellows having put his foot in the chemical. I have knowledge now which would enable me to trace them in many different ways. This, however, is the readiest and, since fortune has put it into our hands, I should be culpable if I neglected it. It has, however, prevented the case from becoming the pretty little intellectual problem which it at one time promised to be. There might have been some credit to be gained out of it, but for this too palpable clue.”
“There is credit, and to spare,” said I. “I assure you, Holmes, that I marvel at the means by which you obtain your results in this case, even more than I did in the Jefferson Hope murder. The thing seems to me to be deeper and more inexplicable. How, for example, could you describe with such confidence the wooden-legged man?”
“Pshaw, my dear boy! it was simplicity itself. I don’t wish to be theatrical. It is all patent and above-board. Two officers who are in command of a convict-guard learn an important secret as to buried treasure. A map is drawn for them by an Englishman named Jonathan Small. You remember that we saw the name upon the chart in Captain Morstan’s possession. He had signed it in behalf of himself and his associates—the sign of the four, as he somewhat dramatically called it. Aided by this chart, the officers—or one of them—gets the treasure and brings it to England, leaving, we will suppose, some condition under which he received it unfulfilled. Now, then, why did not Jonathan Small get the treasure himself? The answer is obvious. The chart is dated at a time when Morstan was brought into close association with convicts. Jonathan Small did not get the treasure because he and his associates were themselves convicts and could not get away.”
“But this is mere speculation,” said I.
“It is more than that. It is the only hypothesis which covers the facts. Let us see how it fits in with the sequel. Major Sholto remains at peace for some years, happy in the possession of his treasure. Then he receives a letter from India which gives him a great fright. What was that?”
“A letter to say that the men whom he had wronged had been set free.”
“Or had escaped. That is much more likely, for he would have known what their term of imprisonment was. It would not have been a surprise to him. What does he do then? He guards himself against a wooden-legged man—a white man, mark you, for he mistakes a white tradesman for him, and actually fires a pistol at him. Now, only one white man’s name is on the chart. The others are Hindoos or Mohammedans. There is no other white man. Therefore we may say with confidence that the wooden-legged man is identical with Jonathan Small. Does the reasoning strike yo as being faulty?”
“No: it is clear and concise.”
“Well, now, let us put ourselves in the place of Jonathan Small. Let us look at it from his point of view. He comes to England with the double idea of regaining what he would consider to be his rights and of having his revenge upon the man who had wronged him. He found out where Sholto lived, and very possibly he established communications with some one inside the house. There is this butler, Lal Rao, whom we have not seen. Mrs. Bernstone gives him far from a good character. Small could not find out, however, where the treasure was hid, for no one ever knew, save the major and one faithful servant who had died. Suddenly Small learns that the major is on his death-bed. In a frenzy lest the secret of the treasure die with him, he runs the gauntlet of the guards, makes his way to the dying man’s window, and is only deterred from entering by the presence of his two sons. Mad with hate, however, against the dead man, he enters the room that night, searches his private papers in the hope of discovering some memorandum relating to the treasure, and finally leaves a momento of his visit in the short inscription upon the card. He had doubtless planned beforehand that should he slay the major he would leave some such record upon the body as a sign that it was not a common murder, but, from the point of view of the four associates, something in the nature of an act of justice. Whimsical and bizarre conceits of this kind are common enough in the annals of crime, and usually afford valuable indications as to the criminal. Do you follow all this?”
“Very clearly.”
“Now, what could Jonathan Small do? He could only continue to keep a secret watch upon the efforts made to find the treasure. Possibly he leaves England and only comes back at intervals. Then comes the discovery of the garret, and he is instantly informed of it. We again trace the presence of some confederate in the household. Jonathan, with his wooden leg, is utterly unable to reach the lofty room of Bartholomew Sholto. He takes with him, however, a rather curious associate, who gets over this difficulty, but dips his naked foot into creosote, whence come Toby, and a six-mile limp for a half-pay officer with a damaged tendo Achillis.”
“But it was the associate, and not Jonathan, who committed the crime.”
“Quite so. And rather to Jonathan’s disgust, to judge by the way the stamped about when he got into the room. He bore no grudge against Bartholomew Sholto, and would have preferred if he could have been simply bound and gagged. He did not wish to put his head in a halter. There was no help for it, however: the savage instincts of his companion had broken out, and the poison had done its work: so Jonathan Small left his record, lowered the treasure-box to the ground, and followed it himself. That was the train of events as far as I can decipher them. Of course as to his personal appearance he must be middle-aged, and must be sunburned after serving his time in such an oven as the Andamans. His height is readily calculated from the length of his stride, and we know that he was bearded. His hairiness was the one point which impressed itself upon Thaddeus Sholto when he saw him at the window. I don’t know that there is anything else.”
“The associate?”
“Ah, well, there is no great mystery in that. But you will know all about it soon enough. How sweet the morning air is! See how that one little cloud floats like a pink feather from some gigantic flamingo. Now the red rim of the sun pushes itself over the London cloud-bank. It shines on a good many folk, but on none, I dare bet, who are on a stranger errand than you and I. How small we feel with our petty ambitions and strivings in the presence of the great elemental forces of nature! Are you well up in your Jean Paul?”
“Fairly so. I worked back to him through Carlyle.”
“That was like following the brook to the parent lake. He makes one curious but profound remark. It is that the chief proof of man’s real greatness lies in his perception of his own smallness. It argues, you see, a power of comparison and of appreciation which is in itself a proof of nobility. There is much food for thought in Richter. You have not a pistol, have you?”
“I have my stick.”
“It is just possible that we may need something of the sort if we get to their lair. Jonathan I shall leave to you, but if the other turns nasty I shall shoot him dead.”
He took out his revolver as he spoke, and, having loaded two of the chambers, he put it back into the right-hand pocket of his jacket.
We had during this time been following the guidance of Toby down the half-rural villa-lined roads which lead to the metropolis. Now, however, we were beginning to come among continuous streets, where labourers and dockmen were already astir, and slatternly women were taking down shutters and brushing doorsteps. At the square-topped corner public-houses business was just beginning, and rough-looking men were emerging, rubbing their sleeves across their beards after their morning wet. Strange dogs sauntered up and stared wonderingly at us as we passed, but our inimitable Toby looked neither to the right nor to the left, but trotted onwards with his nose to the ground and an occasional eager whine which spoke of a hot scent.
