Reflections such as these pervaded Mr. Pottermack's consciousness as he went about his various occupations. They did not seriously disturb his peace of mind, but still they did create a certain degree of unrest, and this presently revived in his mind certain plans which he had considered and rejected; plans for further establishing his security by shifting the field of possible inquiry yet farther from his own neighbourhood.
On Thorndyke the effects of the meeting were quite different. He had come doubting if a certain surmise that he had formed could possibly be correct. He had gone away with his doubts dispelled and his surmise converted into definite belief. The only unsolved question that remained in his mind was, "Who was Marcus Pottermack?" The answer that suggested itself was improbable in the extreme. But it was the only one that he could produce, and if it were wrong he was at the end of his unassisted resources.
The first necessity, therefore, was to eliminate the improbable—or else to confirm it. Then he would know where he stood and could consider what action he would take. Accordingly he began by working up the scanty material that he had collected. The photographs, when developed and enlarged by Polton, yielded two very fair portraits of Mr. Pottermack showing clearly the right and left profiles respectively; and while Polton was dealing with these, his principal made a systematic, but not very hopeful, inspection of the map in search of possible finger-prints. He had made a mental note of the way in which Pottermack had held the map, and even of the spots which his finger-tips had touched, and on these he now began cautiously to operate with two fine powders, a black and a white, applying each to its appropriate background.
The results were poor enough, but yet they were better than he had expected. Pottermack had held the map in his left hand, the better to manipulate the pencil with which he pointed, and his thumb had been planted on a green patch which represented a wood. Here the white powder settled and showed a print which, poor as it was, would present no difficulties to the experts and which would be more distinct in a photograph, as the background would then appear darker. The prints of the finger-tips which the black powder brought out on the white background were more imperfect and were further confused by the black lettering. Still, Thorndyke had them all carefully photographed and enlarged to twice the natural size, and, having blocked out on the negative the surrounding lettering (to avoid giving any information that might be better withheld), had prints made and mounted on card.
With these in his letter-case and the two portraits in his pocket, he set forth one morning for New Scotland Yard, proposing to seek the assistance of his old friend, Mr. Superintendent Miller, or, if he should not be available, that of the officer in charge of criminal records. However, it happened fortunately that the Superintendent was in his office, and thither Thorndyke, having sent in his card, was presently conducted.
"Well, doctor", said Miller, shaking hands heartily, "here you are, gravelled as usual. Now what sort of mess do you want us to help you out of?"
Thorndyke produced his letter-case, and, extracting the photographs, handed them to the Superintendent.
"Here", he said, "are three finger-prints; apparently the thumb and first two fingers of the left hand."
"Ha", said Miller, inspecting the three photographs critically. "Why 'apparently'?"
"I mean", explained Thorndyke, "that that was what I inferred from their position on the original document."
"Which seems to have been a map", remarked Miller, with a faint grin. "Well, I expect you know. Shall I take it that they are the thumb and index and middle finger of the left hand?"
"I think you may", said Thorndyke.
"I think I may", agreed Miller; "and now the question is: What about it? I suppose you want us to tell you whose finger-prints they are; and you want to gammon us that you don't know already. And I suppose—as I see you have been faking the negative—that you don't want to give us any information?"
"In effect", replied Thorndyke, "you have, with your usual acuteness, diagnosed the position exactly. I don't much want to give any details, but I will tell you this much. If my suspicions are correct, these are the finger-prints of a man who has been dead some years."
"Dead!" exclaimed Miller. "Good Lord, doctor, what a vindictive man you are! But you don't suppose that we follow the criminal class into the next world, do you?"
"I have been assuming that you don't destroy records. If you do, you are unlike any government officials that I have ever met. But I hope I was right."
"In the main, you were. We don't keep the whole set of documents of a dead man, but we have a set of skeleton files on which the personal documents—the finger-prints, photographs and description—are preserved. So I expect we shall be able to tell you what you want to know."
"I am sorry", said Thorndyke, "that they are such wretchedly poor prints. You don't think that they are too imperfect to identify, I hope."
Miller inspected the photographs afresh. "I don't see much amiss with them", said he. "You can't expect a crook to go about with a roller and inking-plate in his pocket so as to give you nice sharp prints. These are better than a good many that our people have to work from. And besides, there are three digits from one hand. That gives you part of the formula straight away. No, the experts won't make any trouble about these. But supposing these prints are not on the file?"
"Then we shall take it that I suspected the wrong man."
"Quite so. But, if I am not mistaken, your concern is to prove whose finger-prints they are in order that you can say whose finger-prints they are not. Now, supposing that we don't find them on the files of the dead men, would it help you if we tried the current files—the records of the crooks who are still in business? Or would you rather not?"
"If it would not be giving you too much trouble", said Thorndyke, "I should be very much obliged if you would."
"No trouble at all", said Miller, adding with a sly smile: "only it occurred to me that it might be embarrassing to you if we found your respected client's finger-prints on the live register".
"That would be a highly interesting development" said Thorndyke, "though I don't think it a likely one. But it is just as well to exhaust the possibilities."
"Quite", agreed Miller; and thereupon he wrote the brief particulars on a slip of paper which he put into an envelope with the photographs, and, having rung a bell, handed the envelope to the messenger who appeared in response to the summons.
"I don't suppose we shall have to keep you waiting very long", said the Superintendent. "They have an extraordinarily ingenious system of filing. Out of all the thousands of finger-prints that they have, they can pounce on the one that is wanted in the course of a few minutes. It seems incredible, and yet it is essentially simple—just a matter of classification and ringing the changes on different combinations of types."
"You are speaking of completely legible prints?" suggested Thorndyke.
"Yes, the sort of prints that we get sent in from local prisons for identification of a man who has been arrested under a false name. Of course, when we get a single imperfect print found by the police at a place where a crime has been committed, a bit more time has to be spent. Then we have not only got to place the print, but we've got to make mighty sure that it is the right one, because an arrest and a prosecution hangs on it. You don't want to arrest a man and then, when you come to take his finger-prints properly, find that they are the wrong ones. So, in the case of an imperfect print, you have got to do some careful ridge-tracing and counting and systematic checking of individual ridge-characters, such as bifurcations and islands. But, even so, they don't take so very long over it. The practised eye picks out at a glance details that an unpractised eye can hardly recognize even when they are pointed out."
The Superintendent was proceeding to dilate, with professional enthusiasm, on the wonders of finger-print technique and the efficiency of the Department when his eulogies were confirmed by the entrance of an officer carrying a sheaf of papers and Thorndyke's photographs, whic
h he delivered into Miller's hands.
"Well, doctor", said the Superintendent, after a brief glance at the documents, "here is your information. Jeffrey Brandon is the name of the late lamented. Will that do for you?"
"Yes", replied Thorndyke, "that is the name I expected to hear."
"Good", said Miller. "I see they have kept the whole of his papers for some reason. I will just glance through them while you are doing Thomas Didymus with the finger-prints. But it is quite obvious, if you compare your photographs with the rolled impressions, that the ridge-patterns are identical."
He handed Thorndyke the finger-print sheet, to which were attached the photograph and personal description, and sat down at the table to look over the other documents, while Thorndyke walked over to the window to get a better light. But he did not concern himself with the finger-prints beyond a very brief inspection. It was the photograph that interested him. It showed, on the same print, a right profile and a full face; of which he concentrated his attention on the former. A rather remarkable profile it was, strikingly handsome and curiously classical in outline, rather recalling the head of Antinous in the British Museum. Thorndyke examined it minutely, and then—his back being turned to Miller—he drew from his waistcoat pocket the right profile of Mr. Pottermack and placed it beside the prison photograph.
A single glance made it clear that the two photographs represented the same face. Though one showed a clean-shaven young man with the full lips and strong, rounded chin completely revealed, while the other was a portrait of a bearded, spectacled, middle-aged man, yet they were unmistakably the same. The remarkable nose and brow and the shapely ear were identical in the two photographs; and in both, the lobe of the ear was marked at its tip by a dark spot.
From the photograph he turned to the description. Not that it was necessary to seek further proof; and he did, in fact, merely glance through the particulars. But that rapid glance gathered fresh confirmation. "Height 5 feet 6 inches, hair chestnut, eyes darkish grey, small port-wine mark on lobe of right ear", etc. All the details of Jeffrey Brandon's personal characteristics applied perfectly to Mr. Marcus Pottermack.
"I don't quite see", said Miller, as he took the papers from Thorndyke and laid them on the others, "why they kept all these documents. The conviction doesn't look to me very satisfactory—I don't like these cases where the prosecution has all its eggs in one basket, with the possible chance that they may be bad eggs; and it was a devil of a sentence for a first offence. But as the poor beggar is dead, and no reconsideration of either the conviction or the sentence is possible, there doesn't seem much object in preserving the records. Still, there may have been some reason at the time."
In his own mind, Thorndyke was of opinion that there might have been a very good reason. But he did not communicate this opinion. He had obtained the information that he had sought and was not at all desirous of troubling still waters; and his experience having taught him that Mr. Superintendent Miller was an exceedingly "noticing" gentleman, he thought it best to avoid further discussion and take his departure, after having expressed his appreciation of the assistance that he had received.
Nevertheless, for some time after he had gone, the Superintendent remained wrapped in profound thought; and that his cogitations were in some way concerned with the departed visitor would have been suggested by the circumstance that he sauntered to the window and looked down with a speculative eye on that visitor as he strode across the courtyard towards the Whitehall gate.
Meanwhile Thorndyke's mind was no less busy. As he wended his way Templewards he reviewed the situation in all its bearings. The wildly improbable had turned out to be true. He had made a prodigiously long shot and he had hit the mark: which was gratifying inasmuch as it justified a previous rather hypothetical train of reasoning. Marcus Pottermack, Esq., was undoubtedly the late Jeffrey Brandon. There was now no question about that. The only question that remained was what was to be done in the matter; and that question would have been easier to decide if he had been in possession of more facts. He had heard Mr. Stalker's opinion of the conviction, based on intimate knowledge of the circumstances, and he had heard that of the Superintendent, based on an immense experience of prosecutions. He was inclined to agree with them both; and the more so inasmuch as he had certain knowledge which they had not.
In the end, he decided to take no action at present, but to keep a watchful eye for further developments.
VIII. MR. POTTERMACK SEEKS ADVENTURE
In the last chapter it was stated that one of the effects of Thorndyke's appearance at the side gate of "The Chestnuts", Borley, was to revive in the mind of its tenant certain projects which had been considered and rejected. But perhaps the word "rejected" overstates the case. For the continued existence in a locked drawer in Mr. Pottermack's workshop of a coat which had once been James Lewson's and a bundle of twenty five-pound notes implied a purpose which had been abandoned only conditionally and subject to possible reconsideration.
Again and again, as the destructor which stood in the corner beyond the tool-shed smoked and flared as he fed it with combustible rubbish, had he been on the point of flinging into it the coat and the banknotes and thereby reducing to unrecognizable ash the last visible traces of the tragedy. And every time his hand had been stayed by the thought that possibly, in some circumstances as yet unforeseen, these mementoes of that night of horror might yet be made to play a useful part. So, not without many a twinge of uneasiness, he had let these incriminating objects lie hidden in the locked drawer. And now, as it seemed to him, the circumstances had arisen in which some of them, at least, might be turned to account.
What were those circumstances? Simply the state of mind of the strange lawyer. To the people of Borley, including the police, Lewson was a man who had absconded and vanished. His tracks had shown him striking out across country towards the London road. Those tracks, it is true, broke off short on the heath and had not reappeared elsewhere, but no one doubted that he had gone clear away from the vicinity of Borley and was now in hiding at a safe distance from his old haunts. The natives of the district had never given Mr. Pottermack a moment's anxiety. But with this lawyer the case was different. The disturbing thing about him was that his curiosity, tepid as it was, concerned itself, not with the man who had vanished but with the locality from which he disappeared. But curiosity of that kind, Mr. Pottermack felt, was a thing that was not to be encouraged. On the contrary, it had better be diverted into a more wholesome channel. In short, the time had come when it would be desirable that James Lewson should make his appearance, if only by proxy, in some district as far removed as possible from the neighbourhood of "The Chestnuts", Borley.
So it came about that Mr. Pottermack prepared to set forth along that perilous track beaten smooth by the feet of those who do not know when to let well alone.
For some days after having come to his decision in general terms he was at a loss for a detailed plan. Somehow, the stolen notes had got to be put into circulation. But not by him. The numbers of those notes were known, and, as soon as they began to circulate, some, at least, of them would be identified and would be rigorously traced. The problem was how to get rid of them in a plausible manner without appearing in the transaction; and for some time he could think of no better plan than that of simply dropping them in a quiet London street, a plan which he summarily rejected as not meeting the necessities of the case. The fruitful suggestion eventually came from a newsboy who was roaring "Egbert Bruce's Finals!" outside the station. In an instant, Mr. Pottermack realized that here was the perfect plan, and having purchased a paper, took it home to extract the details on which he proposed to base his strategic scheme.
The "finals" related to a somewhat unselect race-meeting which was to take place in a couple of days' time at Illingham in Surrey, a place conveniently accessible from Borley and yet remote enough to render it unlikely that he would be seen there by any of his fellow-townsmen. Not that his presence there would be in any way susp
icious or incriminating, but, still, the less people knew about his movements the better.
On the appointed day he set forth betimes, neatly but I suitably dressed and all agog for the adventure, tame though it promised to be if it worked according to plan. To Mrs. Gadby he had explained—quite truthfully—that he was going to London; and if she had wanted confirmation of the statement, it could have been supplied by sundry natives of the town with whom he exchanged greetings on the platform as he waited for the London train.
But despite his geniality, he made a point of selecting an empty first-class compartment and shutting himself in. He had no hankering for human companionship. For, beneath the exhilaration engendered by this little adventure was an appreciable tinge of nervousness. No foreseeable contingency threatened his safety; but it is an undeniable fact that a man who carries, buttoned up in his inside breast pocket, twenty stolen banknotes, of which the numbers are known to the police, and of his possession of which he could give no credible account, is not without some reason for nervousness. And that was Mr. Pottermack's position. Just before starting, he had disinterred the whole bundle of those fatal notes and stuffed them into a compartment of the letter-case which he usually carried in his breast pocket. He had also hunted up another letter-case, aged, outworn and shabby, into which he had put a half-dozen ten-shilling notes for the day's expenses and stowed it in the outside hip pocket of his jacket.
As soon as the train had fairly started, he proceeded to make certain rearrangements related to his plan of campaign. Taking out the two letter-wallets—which we may distinguish as the inner and the outer—he laid them on the seat beside him. From the inner wallet he took out five of the stolen notes and placed them loosely in a compartment of the other wallet with their ends projecting so that they were plainly visible when it was open; and from the outer wallet he transferred four of the ten-shilling notes to the inner (he had paid for his ticket in silver). Then he returned the two wallets to their respective pockets and buttoned up his coat.
