"I had spoiled every plate I could find, and had the developed negatives safely in my pocket, when I happened to glance at a porcelain washing-well under the sink. There was one negative in that, and I took it up. It was _not_ a negative of a drawing of yours, but of a Russian twenty-ruble note!"

This _was_ a discovery. The only possible reason any man could have for photographing a bank-note was the manufacture of an etched plate for the production of forged copies. I was almost as pleased as I had been at the discovery of _your_ negatives. He might bring the police now as soon as he liked; I could turn the tables on him completely. I began to hunt about for anything else relating to this negative.

"I found an inking-roller, some old pieces of blanket (used in printing from plates), and in a corner on the floor, heaped over with newspapers and rubbish, a small copying-press. There was also a dish of acid, but not an etched plate or a printed note to be seen. I was looking at the press, with the negative in one hand and the inking-roller in the other, when I became conscious of a shadow across the window. I looked up quickly, and there was Mirsky hanging over from some ledge or projection to the side of the window, and staring straight at me, with a look of unmistakable terror and apprehension.

"The face vanished immediately. I had to move a table to get at the window, and by the time I had opened it there was no sign or sound of the rightful tenant of the room. I had no doubt now of his reason for carrying a parcel down-stairs. He probably mistook me for another visitor he was expecting, and, knowing he must take this visitor into his room, threw the papers and rubbish over the press, and put up his plates and papers in a bundle and secreted them somewhere down-stairs, lest his occupation should be observed.

"Plainly, my duty now was to communicate with the police. So, by the help of my friend the barber down-stairs, a messenger was found and a note sent over to Scotland Yard. I awaited, of course, for the arrival of the police, and occupied the interval in another look round--finding nothing important, however. When the official detective arrived, he recognized at once the importance of the case. A large number of forged Russian notes have been put into circulation on the Continent lately, it seems, and it was suspected that they came from London. The Russian Government have been sending urgent messages to the police here on the subject.

"Of course I said nothing about your business; but, while I was talking with the Scotland Yard man, a letter was left by a messenger, addressed to Mirsky. The letter will be examined, of course, by the proper authorities, but I was not a little interested to perceive that the envelope bore the Russian imperial arms above the words 'Russian Emba.s.sy.' Now, why should Mirsky communicate with the Russian Emba.s.sy? Certainly not to let the officials know that he was carrying on a very extensive and lucrative business in the manufacture of spurious Russian notes. I think it is rather more than possible that he wrote--probably before he actually got your drawings--to say that he could sell information of the highest importance, and that this letter was a reply. Further, I think it quite possible that, when I asked for him by his Russian name and spoke of 'a confidential letter,' he at once concluded that _I_ had come from the emba.s.sy in answer to his letter. That would account for his addressing me in Russian through the key-hole; and, of course, an official from the Russian Emba.s.sy would be the very last person in the world whom he would like to observe any indications of his little etching experiments. But, anyhow, be that as it may," Hewitt concluded, "your drawings are safe now, and if once Mirsky is caught, and I think it likely, for a man in his shirt-sleeves, with scarcely any start, and, perhaps, no money about him, hasn't a great chance to get away--if he is caught, I say, he will probably get something handsome at St. Petersburg in the way of imprisonment, or Siberia, or what not; so that you will be amply avenged."

"Yes, but I don't at all understand this business of the drawings even now. How in the world were they taken out of the place, and how in the world did you find it out?"

"Nothing could be simpler; and yet the plan was rather ingenious. I'll tell you exactly how the thing revealed itself to me. From your original description of the case many people would consider that an impossibility had been performed. n.o.body had gone out and n.o.body had come in, and yet the drawings had been taken away. But an impossibility is an impossibility, after all, and as drawings don't run away of themselves, plainly somebody had taken them, unaccountable as it might seem. Now, as they were in your inner office, the only people who could have got at them besides yourself were your a.s.sistants, so that it was pretty clear that one of them, at least, had something to do with the business. You told me that Worsfold was an excellent and intelligent draughtsman. Well, if such a man as that meditated treachery, he would probably be able to carry away the design in his head--at any rate, a little at a time--and would be under no necessity to run the risk of stealing a set of the drawings. But Ritter, you remarked, was an inferior sort of man. 'Not particularly smart,' I think, were your words--only a mechanical sort of tracer. _He_ would be unlikely to be able to carry in his head the complicated details of such designs as yours, and, being in a subordinate position, and continually overlooked, he would find it impossible to make copies of the plans in the office. So that, to begin with, I thought I saw the most probable path to start on.

"When I looked round the rooms, I pushed open the gla.s.s door of the barrier and left the door to the inner office ajar, in order to be able to see any thing that _might_ happen in any part of the place, without actually expecting any definite development. While we were talking, as it happened, our friend Mirsky (or Hunter--as you please) came into the outer office, and my attention was instantly called to him by the first thing he did. Did you notice anything peculiar yourself?"

"No, really, I can't say I did. He seemed to behave much as any traveler or agent might."

"Well, what I noticed was the fact that as soon as he entered the place he put his walking-stick into the umbrella-stand over there by the door, close by where he stood, a most unusual thing for a casual caller to do, before even knowing whether you were in. This made me watch him closely. I perceived with increased interest that the stick was exactly of the same kind and pattern as one already standing there, also a curious thing. I kept my eyes carefully on those sticks, and was all the more interested and edified to see, when he left, that he took the _other_ stick--not the one he came with--from the stand, and carried it away, leaving his own behind. I might have followed him, but I decided that more could be learned by staying, as, in fact, proved to be the case. This, by the by, is the stick he carried away with him. I took the liberty of fetching it back from Westminster, because I conceive it to be Ritier's property."

Hewitt produced the stick. It was an ordinary, thick Malacca cane, with a buck-horn handle and a silver band. Hewitt bent it across his knee and laid it on the table.

"Yes," Dixon answered, "that is Ritter's stick. I think I have often seen it in the stand. But what in the world----"

"One moment; I'll just fetch the stick Mirsky left behind." And Hewitt stepped across the corridor.

He returned with another stick, apparently an exact fac-simile of the other, and placed it by the side of the other.

"When your a.s.sistants went into the inner room, I carried this stick off for a minute or two. I knew it was not Worsfold's, because there was an umbrella there with his initial on the handle. Look at this."

Martin Hewitt gave the handle a twist and rapidly unscrewed it from the top. Then it was seen that the stick was a mere tube of very thin metal, painted to appear like a Malacca cane.

"It was plain at once that this was no Malacca cane--it wouldn't bend.

Inside it I found your tracings, rolled up tightly. You can get a marvelous quant.i.ty of thin tracing-paper into a small compa.s.s by tight rolling."

"And this--this was the way they were brought back!" the engineer exclaimed. "I see that clearly. But how did they get away? That's as mysterious as ever."

"Not a bit of it! See here. Mirsky gets hold of Ritter, and they agree to get your drawings and photograph them. Ritter is to let his confederate have the drawings, and Mirsky is to bring them back as soon as possible, so that they sha'n't be missed for a moment. Ritter habitually carries this Malacca cane, and the cunning of Mirsky at once suggests that this tube should be made in outward fac-simile. This morning Mirsky keeps the actual stick, and Ritter comes to the office with the tube. He seizes the first opportunity--probably when you were in this private room, and Worsfold was talking to you from the corridor--to get at the tracings, roll them up tightly, and put them in the tube, putting the tube back into the umbrella-stand. At half-past twelve, or whenever it was, Mirsky turns up for the first time with the actual stick and exchanges them, just as he afterward did when he brought the drawings back."

"Yes, but Mirsky came half an hour after they were--Oh, yes, I see. What a fool I was! I was forgetting. Of course, when I first missed the tracings, they were in this walking-stick, safe enough, and I was tearing my hair out within arm's reach of them!"

"Precisely. And Mirsky took them away before your very eyes. I expect Ritter was in a rare funk when he found that the drawings were missed. He calculated, no doubt, on your not wanting them for the hour or two they would be out of the office."

"How lucky that it struck me to jot a pencil-note on one of them! I might easily have made my note somewhere else, and then I should never have known that they had been away."

"Yes, they didn't give you any too much time to miss them. Well, I think the rest pretty clear. I brought the tracings in here, screwed up the sham stick and put it back. You identified the tracings and found none missing, and then my course was pretty clear, though it looked difficult. I knew you would be very naturally indignant with Ritter, so, as I wanted to manage him myself, I told you nothing of what he had actually done, for fear that, in your agitated state, you might burst out with something that would spoil my game. To Ritter I pretended to know nothing of the return of the drawings or _how_ they had been stolen--the only things I did know with certainty. But I _did_ pretend to know all about Mirsky--or Hunter--when, as a matter of fact, I knew nothing at all, except that he probably went under more than one name. That put Ritter into my hands completely. When he found the game was up, he began with a lying confession. Believing that the tracings were still in the stick and that we knew nothing of their return, he said that they had not been away, and that he would fetch them--as I had expected he would. I let him go for them alone, and, when he returned, utterly broken up by the discovery that they were not there, I had him altogether at my mercy. You see, if he had known that the drawings were all the time behind your book-case, he might have brazened it out, sworn that the drawings had been there all the time, and we could have done nothing with him. We couldn't have sufficiently frightened him by a threat of prosecution for theft, because there the things were in your possession, to his knowledge.

"As it was he answered the helm capitally: gave us Mirsky's address on the envelope, and wrote the letter that was to have got him out of the way while I committed burglary, if that disgraceful expedient had not been rendered unnecessary. On the whole, the case has gone very well."

"It has gone marvelously well, thanks to yourself. But what shall I do with Ritter?"

"Here's his stick--knock him down-stairs with it, if you like. I should keep the tube, if I were you, as a memento. I don't suppose the respectable Mirsky will ever call to ask for it. But I should certainly kick Ritter out of doors--or out of window, if you like--without delay."

Mirsky was caught, and, after two remands at the police-court, was extradited on the charge of forging Russian notes. It came out that he had written to the emba.s.sy, as Hewitt had surmised, stating that he had certain valuable information to offer, and the letter which Hewitt had seen delivered was an acknowledgment, and a request for more definite particulars. This was what gave rise to the impression that Mirsky had himself informed the Russian authorities of his forgeries. His real intent was very different, but was never guessed.

"I wonder," Hewitt has once or twice observed, "whether, after all, it would not have paid the Russian authorities better on the whole if I had never investigated Mirsky's little note factory. The Dixon torpedo was worth a good many twenty-ruble notes."

V.

THE QUINTON JEWEL AFFAIR.

It was comparatively rarely that Hewitt came into contact with members of the regular criminal cla.s.s--those, I mean, who are thieves, of one sort or another, by exclusive profession. Still, n.o.body could have been better prepared than Hewitt for encountering this cla.s.s when it became necessary.

By some means, which I never quite understood, he managed to keep abreast of the very latest fashions in the ever-changing slang dialect of the fraternity, and he was a perfect master of the more modern and debased form of Romany. So much so that frequently a gypsy who began (as they always do) by pretending that he understood nothing, and never heard of a gypsy language, ended by confessing that Hewitt could _rokker_ better than most Romany _chals_ themselves.

By this acquaintance with their habits and talk Hewitt was sometimes able to render efficient service in cases of especial importance. In the Quinton jewel affair Hewitt came into contact with a very accomplished thief.

The case will probably be very well remembered. Sir Valentine Quinton, before he married, had been as poor as only a man of rank with an old country establishment to keep up can be. His marriage, however, with the daughter of a wealthy financier had changed all that, and now the Quinton establishment was carried on on as lavish a scale as might be; and, indeed, the extravagant habits of Lady Quinton herself rendered it an extremely lucky thing that she had brought a fortune with her.

Among other things her jewels made quite a collection, and chief among them was the great ruby, one of the very few that were sent to this country to be sold (at an average price of somewhere about twenty thousand pounds apiece, I believe) by the Burmese king before the annexation of his country. Let but a ruby be of a great size and color, and no equally fine diamond can approach its value. Well, this great ruby (which was set in a pendant, by the by), together with a necklace, brooches, bracelets, ear-rings--indeed, the greater part of Lady Quinton's collection--were stolen. The robbery was effected at the usual time and in the usual way in cases of carefully planned jewelry robberies. The time was early evening--dinner-time, in fact--and an entrance had been made by the window to Lady Quinton's dressing-room, the door screwed up on the inside, and wires artfully stretched about the grounds below to overset anybody who might observe and pursue the thieves.

On an investigation by London detectives, however, a feature of singularity was brought to light. There had plainly been only one thief at work at Radcot Hall, and no other had been inside the grounds. Alone he had planted the wires, opened the window, screwed the door, and picked the lock of the safe. Clearly this was a thief of the most accomplished description.

Some few days pa.s.sed, and, although the police had made various arrests, they appeared to be all mistakes, and the suspected persons were released one after another. I was talking of the robbery with Hewitt at lunch, and asked him if he had received any commission to hunt for the missing jewels.

"No," Hewitt replied, "I haven't been commissioned. They are offering an immense reward however--a very pleasant sum, indeed. I have had a short note from Radcot Hall informing me of the amount, and that's all. Probably they fancy that I may take the case up as a speculation, but that is a great mistake. I'm not a beginner, and I must be commissioned in a regular manner, hit or miss, if I am to deal with the case. I've quite enough commissions going now, and no time to waste hunting for a problematical reward."

But we were nearer a clue to the Quinton jewels than we then supposed.

We talked of other things, and presently rose and left the restaurant, strolling quietly toward home. Some little distance from the Strand, and near our own door, we pa.s.sed an excited Irishman--without doubt an Irishman by appearance and talk--who was pouring a torrent of angry complaints in the ears of a policeman. The policeman obviously thought little of the man's grievances, and with an amused smile appeared to be advising him to go home quietly and think no more about it. We pa.s.sed on and mounted our stairs. Something interesting in our conversation made me stop for a little while at Hewitt's office door on my way up, and, while I stood there, the Irishman we had seen in the street mounted the stairs. He was a poorly dressed but st.u.r.dy-looking fellow, apparently a laborer, in a badly-worn best suit of clothes. His agitation still held him, and without a pause he immediately burst out:

"Which of ye jintlemen will be Misther Hewitt, sor?"

"This is Mr. Hewitt," I said. "Do you want him?"

"It's protecshin I want, sor--protecshin! I spake to the polis, an' they laff at me, begob. Foive days have I lived in London, an' 'tis nothin' but battle, murdher, an' suddhen death for me here all day an' ivery day! An'

the polis say I'm dhrunk!"

He gesticulated wildly, and to me it seemed just possible that the police might be right.

"They say I'm drunk, sor," he continued, "but, begob, I b'lieve they think I'm mad. An' me being thracked an' folleyed an' dogged an' waylaid an'

poisoned an' blandandhered an' kidnapped an' murdhered, an' for why I do not know!"
