The Press, Watson, is a most valuable institution, if you only know how to use it. And now, if you have quite finished, we will hark back to Kensington and see what the manager of Harding Brothers has to say on the matter."

The founder of that great emporium proved to be a brisk, crisp little person, very dapper and quick, with a clear head and a ready tongue.

"Yes, sir, I have already read the account in the evening papers. Mr. Horace Harker is a customer of ours. We supplied him with the bust some months ago. We ordered three busts of that sort from Gelder & Co., of Stepney. They are all sold now. To whom? Oh, I daresay by consulting our sales book we could very easily tell you. Yes, we have the entries here. One to Mr. Harker you see, and one to Mr. Josiah Brown, of Laburnum Lodge, Laburnum Vale, Chiswick, and one to Mr. Sandeford, of Lower Grove Road, Reading. No, I have never seen this face which you show me in the photograph. You would hardly forget it, would you, sir, for I've seldom seen an uglier. Have we any Italians on the staff? Yes, sir, we have several among our work people and cleaners. I daresay they might get a peep at that sales book if they wanted to. There is no particular reason for keeping a watch upon that book. Well, well, it's a very strange business, and I hope that you will let me know if anything comes of your inquiries."

Holmes had taken several notes during Mr. Harding's evidence, and I could see that he was thoroughly satisfied by the turn which affairs were taking. He made no remark, however, save that, unless we hurried, we should be late for our appointment with Lestrade. Sure enough, when we reached Baker Street the detective was already there, and we found him pacing up and down in a fever of impatience. His look of importance showed that his day's work had not been in vain.

"Well?" he asked. "What luck, Mr. Holmes?"

"We have had a very busy day, and not entirely a wasted one," my friend explained. "We have seen both the retailers and also the wholesale manufacturers. I can trace each of the busts now from the beginning."

"The busts" cried Lestrade. "Well, well, you have your own methods, Mr. Sherlock Holmes, and it is not for me to say a word against them, but I think I have done a better day's work than you. I have identified the dead man."

"You don't say so?"

"And found a cause for the crime."

"Splendid!"

"We have an inspector who makes a specialty of Saffron Hill and the Italian Quarter. Well, this dead man had some Catholic emblem round his neck, and that, along with his colour, made me think he was from the South. Inspector Hill knew him the moment he caught sight of him. His name is Pietro Venucci, from Naples, and he is one of the greatest cut-throats in London. He is connected with the Mafia, which, as you know, is a secret political society, enforcing its decrees by murder. Now, you see how the affair begins to clear up. The other fellow is probably an Italian also, and a member of the Mafia. He has broken the rules in some fashion. Pietro is set upon his track. Probably the photograph we found in his pocket is the man himself, so that he may not knife the wrong person. He dogs the fellow, he sees him enter a house, he waits outside for him, and in the scuffle he receives his own death-wound. How is that, Mr. Sherlock Holmes?"

Holmes clapped his hands approvingly.

"Excellent, Lestrade, excellent!" he cried. "But I didn't quite follow your explanation of the destruction of the busts."

"The busts! You never can get those busts out of your head. After all, that is nothing; petty larceny, six months at the most. It is the murder that we are really investigating, and I tell you that I am gathering all the threads into my hands."

"And the next stage?"

"Is a very simple one. I shall go down with Hill to the Italian Quarter, find the man whose photograph we have got, and arrest him on the charge of murder. Will you come with us?"

"I think not. I fancy we can attain our end in a simpler way. I can't say for certain, because it all depends – well, it all depends upon a factor which is completely outside our control. But I have great hopes – in fact, the betting is exactly two to one – that if you will come with us to-night I shall be able to help you to lay him by the heels."

"In the Italian Quarter?"

"No, I fancy Chiswick is an address which is more likely to find him. If you will come with me to Chiswick to-night, Lestrade, I'll promise to go to the Italian Quarter with you to-morrow, and no harm will be done by the delay. And now I think that a few hours' sleep would do us all good, for I do not propose to leave before eleven o'clock, and it is unlikely that we shall be back before morning. You'll dine with us, Lestrade, and then you are welcome to the sofa until it is time for us to start. In the meantime, Watson, I should be glad if you would ring for an express messenger, for I have a letter to send and it is important that it should go at once."

Holmes spent the evening in rummaging among the files of the old daily papers with which one of our lumber-rooms was packed. When at last he descended, it was with triumph in his eyes, but he said nothing to either of us as to the result of his researches. For my own part, I had followed step by step the methods by which he had traced the various windings of this complex case, and, though I could not yet perceive the goal which we would reach, I understood clearly that Holmes expected this grotesque criminal to make an attempt upon the two remaining busts, one of which, I remembered, was at Chiswick. No doubt the object of our journey was to catch him in the very act, and I could not but admire the cunning with which my friend had inserted a wrong clue in the evening paper, so as to give the fellow the idea that he could continue his scheme with impunity. I was not surprised when Holmes suggested that I should take my revolver with me. He had himself picked up the loaded hunting-crop, which was his favourite weapon.

A four-wheeler was at the door at eleven, and in it we drove to a spot at the other side of Hammersmith Bridge. Here the cabman was directed to wait. A short walk brought us to a secluded road fringed with pleasant houses, each standing in its own grounds. In the light of a street lamp we read "Laburnum Villa" upon the gate-post of one of them. The occupants had evidently retired to rest, for all was dark save for a fanlight over the hall door, which shed a single blurred circle on to the garden path. The wooden fence which separated the grounds from the road threw a dense black shadow upon the inner side, and here it was that we crouched.

"I fear that you'll have a long wait," Holmes whispered. "We may thank our stars that it is not raining. I don't think we can even venture to smoke to pass the time. However, it's a two to one chance that we get something to pay us for our trouble."

It proved, however, that our vigil was not to be so long as Holmes had led us to fear, and it ended in a very sudden and singular fashion. In an instant, without the least sound to warn us of his coming, the garden gate swung open, and a lithe, dark figure, as swift and active as an ape, rushed up the garden path. We saw it whisk past the light thrown from over the door and disappear against the black shadow of the house. There was a long pause, during which we held our breath, and then a very gentle creaking sound came to our ears. The window was being opened. The noise ceased, and again there was a long silence. The fellow was making his way into the house. We saw the sudden flash of a dark lantern inside the room. What he sought was evidently not there, for again we saw the flash through another blind, and then through another.

"Let us get to the open window. We will nab him as he climbs out," Lestrade whispered.

But before we could move, the man had emerged again. As he came out into the glimmering patch of light, we saw that he carried something white under his arm. He looked stealthily all round him. The silence of the deserted street reassured him. Turning his back upon us he laid down his burden, and the next instant there was the sound of a sharp tap, followed by a clatter and rattle. The man was so intent upon what he was doing that he never heard our steps as we stole across the grass plot. With the bound of a tiger Holmes was on his back, and an instant later Lestrade and I had him by either wrist, and the handcuffs had been fastened. As we turned him over I saw a hideous, sallow face, with writhing, furious features, glaring up at us, and I knew that it was indeed the man of the photograph whom we had secured.

But it was not our prisoner to whom Holmes was giving his attention. Squatted on the doorstep, he was engaged in most carefully examining that which the man had brought from the house. It was a bust of Napoleon, like the one which we had seen that morning, and it had been broken into similar fragments. Carefully Holmes held each separate shard to the light, but in no way did it differ from any other shattered piece of plaster. He had just completed his examination when the hall lights flew up, the door opened, and the owner of the house, a jovial, rotund figure in shirt and trousers, presented himself.

"Mr. Josiah Brown, I suppose?" said Holmes.

"Yes, sir; and you, no doubt, are Mr. Sherlock Holmes? I had the note which you sent by the express messenger, and I did exactly what you told me. We locked every door on the inside and awaited developments. Well, I'm very glad to see that you have got the rascal. I hope, gentlemen, that you will come in and have some refreshment."

However, Lestrade was anxious to get his man into safe quarters, so within a few minutes our cab had been summoned and we were all four upon our way to London. Not a word would our captive say, but he glared at us from the shadow of his matted hair, and once, when my hand seemed within his reach, he snapped at it like a hungry wolf. We stayed long enough at the police-station to learn that a search of his clothing revealed nothing save a few shillings and a long sheath knife, the handle of which bore copious traces of recent blood.

"That's all right," said Lestrade, as we parted. "Hill knows all these gentry, and he will give a name to him. You'll find that my theory of the Mafia will work out all right. But I'm sure I am exceedingly obliged to you, Mr. Holmes, for the workmanlike way in which you laid hands upon him. I don't quite understand it all yet."

"I fear it is rather too late an hour for explanations," said Holmes. "Besides, there are one or two details which are not finished off, and it is one of those cases which are worth working out to the very end. If you will come round once more to my rooms at six o'clock to-morrow, I think I shall be able to show you that even now you have not grasped the entire meaning of this business, which presents some features which make it absolutely original in the history of crime. If ever I permit you to chronicle any more of my little problems, Watson, I foresee that you will enliven your pages by an account of the singular adventure of the Napoleonic busts."

When we met again next evening, Lestrade was furnished with much information concerning our prisoner. His name, it appeared, was Beppo, second name unknown. He was a well-known ne'er-do-well among the Italian colony. He had once been a skilful sculptor and had earned an honest living, but he had taken to evil courses and had twice already been in jail – once for a petty theft, and once, as we had already heard, for stabbing a fellow-countryman. He could talk English perfectly well. His reasons for destroying the busts were still unknown, and he refused to answer any questions upon the subject, but the police had discovered that these same busts might very well have been made by his own hands, since he was engaged in this class of work at the establishment of Gelder & Co. To all this information, much of which we already knew, Holmes listened with polite attention, but I, who knew him so well, could clearly see that his thoughts were elsewhere, and I detected a mixture of mingled uneasiness and expectation beneath that mask which he was wont to assume. At last he started in his chair, and his eyes brightened. There had been a ring at the bell. A minute later we heard steps upon the stairs, and an elderly red-faced man with grizzled side-whiskers was ushered in. In his right hand he carried an old-fashioned carpet-bag, which he placed upon the table.

"Is Mr. Sherlock Holmes here?"

My friend bowed and smiled. "Mr. Sandeford, of Reading, I suppose?" said he.

"Yes, sir, I fear that I am a little late, but the trains were awkward. You wrote to me about a bust that is in my possession."

"Exactly."

"I have your letter here. You said, 'I desire to possess a copy of Devine's Napoleon, and am prepared to pay you ten pounds for the one which is in your possession.' Is that right?"

"Certainly."

"I was very much surprised at your letter, for I could not imagine how you knew that I owned such a thing."

"Of course you must have been surprised, but the explanation is very simple. Mr. Harding, of Harding Brothers, said that they had sold you their last copy, and he gave me your address."

"Oh, that was it, was it? Did he tell you what I paid for it?"

"No, he did not."

"Well, I am an honest man, though not a very rich one. I only gave fifteen shillings for the bust, and I think you ought to know that before I take ten pounds from you.

"I am sure the scruple does you honour, Mr. Sandeford. But I have named that price, so I intend to stick to it."

"Well, it is very handsome of you, Mr. Holmes. I brought the bust up with me, as you asked me to do. Here it is!" He opened his bag, and at last we saw placed upon our table a complete specimen of that bust which we had already seen more than once in fragments.

Holmes took a paper from his pocket and laid a ten-pound note upon the table.

"You will kindly sign that paper, Mr. Sandeford, in the presence of these witnesses. It is simply to say that you transfer every possible right that you ever had in the bust to me. I am a methodical man, you see, and you never know what turn events might take afterwards. Thank you, Mr. Sandeford; here is your money, and I wish you a very good evening."

When our visitor had disappeared, Sherlock Holmes's movements were such as to rivet our attention. He began by taking a clean white cloth from a drawer and laying it over the table. Then he placed his newly acquired bust in the centre of the cloth. Finally, he picked up his hunting-crop and struck Napoleon a sharp blow on the top of the head. The figure broke into fragments, and Holmes bent eagerly over the shattered remains. Next instant, with a loud shout of triumph he held up one splinter, in which a round, dark object was fixed like a plum in a pudding.

"Gentlemen," he cried, "let me introduce you to the famous black pearl of the Borgias."

Lestrade and I sat silent for a moment, and then, with a spontaneous impulse, we both broke at clapping, as at the well-wrought crisis of a play. A flush of colour sprang to Holmes's pale cheeks, and he bowed to us like the master dramatist who receives the homage of his audience. It was at such moments that for an instant he ceased to be a reasoning machine, and betrayed his human love for admiration and applause. The same singularly proud and reserved nature which turned away with disdain from popular notoriety was capable of being moved to its depths by spontaneous wonder and praise from a friend.

"Yes, gentlemen," said he, "it is the most famous pearl now existing in the world, and it has been my good fortune, by a connected chain of inductive reasoning, to trace it from the Prince of Colonna's bedroom at the Dacre Hotel, where it was lost, to the interior of this, the last of the six busts of Napoleon which were manufactured by Gelder & Co., of Stepney. You will remember, Lestrade, the sensation caused by the disappearance of this valuable jewel and the vain efforts of the London police to recover it. I was myself consulted upon the case, but I was unable to throw any light upon it. Suspicion fell upon the maid of the Princess, who was an Italian, and it was proved that she had a brother in London, but we failed to trace any connection between them. The maid's name was Lucretia Venucci, and there is no doubt in my mind that this Pietro who was murdered two nights ago was the brother. I have been looking up the dates in the old files of the paper, and I find that the disappearance of the pearl was exactly two days before the arrest of Beppo, for some crime of violence – an event which took place in the factory of Gelder & Co., at the very moment when these busts were being made. Now you clearly see the sequence of events, though you see them, of course, in the inverse order to the way in which they presented themselves to me. Beppo had the pearl in his possession. He may have stolen it from Pietro, he may have been Pietro's confederate, he may have been the go-between of Pietro and his sister. It is of no consequence to us which is the correct solution.

"The main fact is that he HAD the pearl, and at that moment, when it was on his person, he was pursued by the police. He made for the factory in which he worked, and he knew that he had only a few minutes in which to conceal this enormously valuable prize, which would otherwise be found on him when he was searched. Six plaster casts of Napoleon were drying in the passage. One of them was still soft. In an instant Beppo, a skilful workman, made a small hole in the wet plaster, dropped in the pearl, and with a few touches covered over the aperture once more. It was an admirable hiding-place. No one could possibly find it. But Beppo was condemned to a year's imprisonment, and in the meanwhile his six busts were scattered over London. He could not tell which contained his treasure. Only by breaking them could he see. Even shaking would tell him nothing, for as the plaster was wet it was probable that the pearl would adhere to it – as, in fact, it has done. Beppo did not despair, and he conducted his search with considerable ingenuity and perseverance. Through a cousin who works with Gelder, he found out the retail firms who had bought the busts. He managed to find employment with Morse Hudson, and in that way tracked down three of them. The pearl was not there. Then, with the help of some Italian employe, he succeeded in finding out where the other three busts had gone. The first was at Harker's. There he was dogged by his confederate, who held Beppo responsible for the loss of the pearl, and he stabbed him in the scuffle which followed."

"If he was his confederate, why should he carry his photograph?" I asked.

"As a means of tracing him, if he wished to inquire about him from any third person. That was the obvious reason. Well, after the murder I calculated that Beppo would probably hurry rather than delay his movements. He would fear that the police would read his secret, and so he hastened on before they should get ahead of him. Of course, I could not say that he had not found the pearl in Harker's bust. I had not even concluded for certain that it was the pearl, but it was evident to me that he was looking for something, since he carried the bust past the other houses in order to break it in the garden which had a lamp overlooking it. Since Harker's bust was one in three, the chances were exactly as I told you – two to one against the pearl being inside it. There remained two busts, and it was obvious that he would go for the London one first. I warned the inmates of the house, so as to avoid a second tragedy, and we went down, with the happiest results. By that time, of course, I knew for certain that it was the Borgia pearl that we were after. The name of the murdered man linked the one event with the other. There only remained a single bust – the Reading one – and the pearl must be there. I bought it in your presence from the owner – and there it lies."

We sat in silence for a moment.

"Well," said Lestrade, "I've seen you handle a good many cases, Mr. Holmes, but I don't know that I ever knew a more workmanlike one than that. We're not jealous of you at Scotland Yard. No, sir, we are very proud of you, and if you come down to-morrow, there's not a man, from the oldest inspector to the youngest constable, who wouldn't be glad to shake you by the hand."

"Thank you!" said Holmes. "Thank you!" and as he turned away, it seemed to me that he was more nearly moved by the softer human emotions than I had ever seen him. A moment later he was the cold and practical thinker once more. "Put the pearl in the safe, Watson," said he, "and get out the papers of the Conk-Singleton forgery case. Good-bye, Lestrade. If any little problem comes your way, I shall be happy, if I can, to give you a hint or two as to its solution."
