"I will add only one further observation. If you find that deceased made away with himself, as the evidence seems to prove, I think you will agree with me that, at the time and for some days previously, he was not in his right mind. If that is your view, I will ask you to embody it in your verdict."
At the conclusion of the coroner's address, the jury consulted together. But their consultation occupied only a minute or two. Apparently they had already made up their minds, as they might well have done, taking the evidence at its face value. When the whispered conference came to an end, the foreman announced that they had agreed on their verdict and the coroner then put the formal question: "And what is your decision, gentlemen?"
"We find," was the reply, "that deceased committed suicide by hanging himself while temporarily insane."
"Yes," said the coroner, "I am in entire agreement with you, and I must thank you for the care and attention with which you have considered the evidence."
As the proceedings came to an end, Thorndyke and I rose and made our way out, leaving Brodribb in conversation with the coroner and the Superintendent.
"Well," I said as we halted outside to wait for our friend, "it has been quite entertaining, but I don't see that we have got much for our attendance."
"We have got one fact, at least," replied Thorndyke, "that was worth coming for. We now know that Holker was in the house until after the rain had begun to fall. That clears away any uncertainties on a point of vital importance. But we had better not discuss the case now. And I think—though it seems rather scurvy treatment of our old friend—but I think we had better keep our own counsel. Brodribb accepts the suicide as an established fact, and perhaps it is as well that he should. If we are going to work at this case, it will be all to the good that we hold the monopoly of the real facts. It will be a difficult and obscure case, but the difficulty will be materially reduced if we can watch the development of events quietly, without anyone suspecting that we are watching. This was no crime of sudden impulse. It was premeditated and arranged. Obviously there was, behind it, some perfectly definite motive. We have, among other things, to discover what that motive was. The criminals at present believe themselves to be entirely unsuspected. If they maintain that belief, they will feel at liberty to pursue their purpose without any special precautions; and we—also unsuspected—may get our chance. But here comes Brodribb."
I must confess that Thorndyke's observations appeared to me so cryptic as to convey no meaning whatever. That, I recognised, was owing to my own "slowness in the uptake." However, there was no opportunity to seek elucidation, for Brodribb had seen us and was now bearing down on us. He replied to our greeting with something less than his usual vivacity, and we set forth on our way to the station in almost uninterrupted silence.
X. A SUMMARY OF THE EVIDENCE
(Dr. Jervis's Narrative)
Mr. Brodribb's taciturn mood persisted even after we had taken possession of an empty first-class smoking compartment and lit our pipes. Evidently his recent experiences had depressed him profoundly; which, after all, was no matter for surprise. An inquest is not a jovial function under the most favourable conditions, and the conditions in the recent inquiry had been far from favourable for the friends of the deceased.
"It was a ghoulish business," he remarked in semi-apologetic explanation of his low spirits, "but, of course, it had to be; and the coroner managed it as decently as possible. Still, I had rather that he had managed without me."
"If he had," said I, "he would have missed what he regarded as most important evidence."
"Yes, I know," replied Brodribb. "That was what I felt, though I hated giving that evidence. The affair had to be cleared up, and I have no doubt that the jury were right in their verdict. I know you don't agree with me, Thorndyke, but I think your special experience has misled you for once."
"There is always the possibility," Thorndyke admitted, "that professional bias may influence one. In any case, our divergence of views does not affect the position in practice. The death of Sir Edward is an established fact and the ambiguity of your legal status is at an end."
"Yes," Brodribb agreed, "there is that very unsatisfactory compensation. I am now the executor and can act as I think best. I could only wish that the best course of action were a little more easy to decide on."
With this, he relapsed into silent reflection, possibly connected with the difficulties suggested by his last sentence; and as Thorndyke and I were unable to discuss before him the matters that were occupying our thoughts, we followed his example and devoted ourselves to the consideration of our own affairs.
Suddenly Brodribb sat up with a start and began to rummage in his inside breast-pocket. "Bless my soul!" he exclaimed. "What a fool I am! Clean forgot this. Ought to have mentioned it in my evidence."
Here he brought out a letter wallet, and, taking from it an envelope, opened the latter and tipped some small object out on to his palm.
"There!" he said, holding out his open hand to Thorndyke. "What do you think of that?"
Thorndyke picked up the object, and, having examined it, held it up to the light, when I saw that it was a little oval plate of a bright transparent green bearing an engraved device which I recognised instantly.
"The missing seal!" I exclaimed, taking it from Thorndyke to inspect it more closely. "Then we may assume that the great mystery is solved."
"Indeed, you may assume nothing of the kind," said Brodribb. "On the contrary, the mystery is more profound than ever and the chance of a solution more remote. I will tell you all about it—all that I know, that is to say. It is a queer story. Your friend, Superintendent Miller, brought it to me yesterday afternoon to compare with my seals and for formal identification by me (which I thought very kind and courteous of him), and this is the account he gave of its discovery.
"It seems that, about a week ago, a man escaped from Pentonville Gaol. I understand that he got away in the evening, and in some miraculous fashion—you know where the prison is; right in the middle of a populous neighbourhood—he kept out of sight until it was dark, which wouldn't have been much before eleven at this time of year. Then, with the same miraculous luck, he managed to slip away through the streets, right across the northern suburbs to the neighbourhood of Temple Mills by the River Lea.
"There he was lurking the next afternoon when he had another stroke of luck. Some devotee of the simple life had elected to take a bath in the river, and he must have strayed away some distance from his clothes, for our Pentonville sportsman found them unguarded. Possibly he may have watched the other sportsman taking them off. At any rate, he seized the opportunity; slipped off the prison clothes and popped on the others. Then he nipped off across the meadows in the direction of Tottenham. And there it was that his luck deserted him; for, by the merest chance, a plain clothes officer who knew him by sight, happened to meet him, and, as the hue and cry was out, he collared him forthwith.
"And now comes one of the quaint features of the story. At Tottenham Police Station they went through his pockets—they were really the other fellow's, of course—with mighty little result. The next day they took him back to Pentonville, and once more he was put into uniform. The clothes that were taken off him were put aside until they could be disposed of in some way. But a couple of days ago it occurred to one of the officers to go over them carefully to see if he could find out the lawful owner. And then he made a discovery. Apparently, the owner of those clothes was a pickpocket, for there was a secret receptacle in the back of the waistcoat, which had been overlooked at the first search; and in that secret pocket the officer found this stone."
"And what happened to the other man?" I asked.
"Ah!" chuckled Brodribb, quite recovering his natural spirits for the time being, "that's the cream of the joke. He found the gaol-bird's discarded garments in place of his own clothes and of course he had to put 'em on, since he couldn't go about naked. It was a lovely situation; almost as if he had walked into prison and locked
himself in. However, as soon as he was dressed in his proper character, he made a bolt for it; and he had even better luck than the other fellow. In some perfectly incredible manner, he made his way, in broad daylight, right across North London and came to the surface at the Angel, of all unlikely places."
"At the Angel!" I repeated, incredulously.
"At the Angel," Brodribb reiterated, joyously. "Just picture to yourselves an escaped convict in full uniform, elbowing his way through the crowd at the Angel! Well, of course, it couldn't go on. A couple of plain-clothes men saw him and pounced on him in an instant. It looked as if his luck had given out. But apparently his wits were as nimble as his heels, for he got just a dog's chance and he took it. At the moment when the two constables were taking him across the road, a fire-engine came thundering along and they had to scuttle back out of the way. But as it flew past, our friend made a grab at the rail of the foot-plate and held on. The momentum of the engine whisked him out of the clutches of his captors and sent them sprawling; and when they got up, their prisoner was standing on the foot-plate and fading in the distance before their eyes. Of course, it is no use shouting after a fire-engine.
"Now the odd thing is," Mr. Brodribb continued in a slightly shaky voice, "that none of the fire-men on the engine seem to have noticed him; and the constables couldn't telephone a warning until they had found out where the fire was. So our friend stuck on the engine until it turned down Tottenham Court Road, when he hopped off and made a bolt down Warren Street. Naturally, he soon picked up some followers, but he kept ahead of them, flying up one street and down another until he arrived at Cleveland Mews with half the town at his heels. He turned into the mews, still well ahead, and shot down it like a rocket. And that was the last that was seen of him. The crowd and the police surged in after him, and as the mews is a blind alley, they were quite cocksure that they'd got him. But when they came to the blind end, there was not a sign of him. He had vanished into thin air. And he had vanished for good, you observe. For, as nobody knew who he was, nobody could identify him when once he had changed his clothes."
"No," I agreed, "he has got clear away, and I must admit that I think he deserved to."
"I am afraid that I agree with you," said Brodribb. "Very improper for a lawyer, but even lawyers are human. But the police were very puzzled; not only as to how he had managed to escape, but, when the real convict was captured, they couldn't make out why he ran away. Of course, when the seal was found in the pocket, they understood."
"I wonder how he did get away," said I.
"So do I," said Brodribb. "It was a remarkable exploit. I examined the place myself and could see no apparent way of escape."
"You examined the place?" I exclaimed in surprise.
"Yes. I forgot to mention that, by a remarkable coincidence, I happened to be there at the very time. I took Sir Giles Farnaby to see a client of mine who has a studio that fronts on the mews. When we arrived the police were actually searching the studio. They thought the fugitive might have got in at the open window, unnoticed by the two ladies who were at work there. So they went all over the premises. Just as well for our friend that they did; for while they were searching the studio premises he had time to make his little arrangements at the bottom of the mews. And now we shall never know how he came by that seal, though, as he seems to have been a pickpocket, we can make a pretty likely guess."
"Yes," Thorndyke agreed a little dryly, "it is always possible to guess. But guesses are not very valuable evidential assets. The police guessed that this man was a pickpocket, and we can guess that, being a pickpocket, he obtained the seal in the practice of his art. That guess is supported by the fact that the ring is the only article known to be missing from his person, and that the leather case in which it was usually carried, is also missing. On the other hand, it is not in agreement with the fact that the stone had been dismounted from the ring and that the ring was not found with it. The pickpocket usually takes his booty to the receiver as he finds it. It is the receiver who extracts the stones and melts down the metal. That is the usual procedure, but, naturally, there are exceptions."
"At any rate," said Brodribb, "what matters to us is that the man has vanished and no one knows who he is."
On this conclusion neither Thorndyke nor I made any comment, and the discussion was brought to an end by our arrival at Liverpool Street, where we saw Mr. Brodribb into a hansom and then embarked in another for the Temple.
During the meal which we found awaiting us at our chambers, I endeavoured to extract from Thorndyke some elucidation of the statement that had seemed to me so obscure. But he was not willing to enter into details at present.
"The position at the moment, Jervis," said he, "is this. We have no doubt whatever that Sir Edward Hardcastle was murdered. We have evidence that the murder was premeditated and the methods planned in advance with considerable care and some ingenuity. It was carried out by more than one, and probably several persons. It was, in fact, of the nature of a conspiracy. The purpose of the murder was not robbery from the person. The perpetrators, or at least some of them, were apparently of a low class, socially; and the victim seems to have walked, not entirely unsuspecting, into some sort of ambush.
"That is all that we know at present, and it doesn't carry us far. What we have to discover, if we can, is the identity of the murderers. If we can do that, the motive will disclose itself. If, on the other hand, we can uncover the motive, that will probably point to the murderers. We must proceed along both lines if we can. We must endeavour cautiously to ascertain whether Sir Edward had any enemies who might conceivably have been capable of a crime of revenge; and we must watch the consequences of his death and note who benefits by them."
"It is evident," said I, "that someone is going to benefit to the extent of a title and an uncommonly valuable estate."
"Yes, and we shall bear that in mind. But we mustn't attach undue weight to it. Whenever a well-to-do person is murdered, the heirs benefit; but that fact—though it furnishes a conceivable motive—does not cast suspicion on them in the absence of any other evidence. In practice, as you know, I like to leave the question of motive until I have got a lead in some definite direction. It is much safer. The premature consideration of motive may be very misleading, whereas its use as corroboration may be invaluable."
"Yes, I realise that," said I, "but in this case I don't see how you are going to get a lead. The murderers left plenty of traces of a kind; but they were the wrong kind. There was nothing personal about them—unless the finger-prints can be identified, and I doubt if they can. They were very confused and obscure. And even if they could be made out, they would be of no use unless they were the prints of criminals known to the police and recorded at the register."
Thorndyke laughed grimly. "My learned friend," he remarked, "is not disposed to be encouraging. But never mind. We have made many a worse start and yet reached our goal. Presently we will examine our material and see what it has to tell us. Perhaps we may get a lead in some direction from an unexpected source."
At the actual examination I was not present, for our expeditions to Stratford had left me with one or two unfulfilled engagements. Accordingly, as soon as we had finished our supper (or dinner—the exact status of our evening meal was not clearly defined), I went forth to despatch one of them, my regret tempered by the consideration that I should miss nothing but the mere manipulations, most of which were now fairly familiar to me, and that on my return I should find most of the work done and the results available.
And so it turned out. Re-entering our chambers about half-past ten and finding the sitting-room untenanted, I made my way up to the laboratory where a glance around told me that the final stage of the investigation had been reached. On one bench was a microscope and a row of slides, each bearing a temporary or permanent label; on the chemical bench a sand-bath stood over a bunsen burner and bore a small glass evaporating dish, and one or two large watch-glasses containing fluid with a crystalline mar
gin had apparently had their turn on the bath. Beside them in a beaker of fluid—presumably water—was the collar that had been abstracted from the mortuary by Thorndyke, who was at the moment gently prodding it with a glass rod, while his familiar demon, Polton, was engaged in vigorously wringing out the end of rope in a basin of hot liquid which exhaled the unmistakable aroma of soft soap.
"We have nearly finished," said Thorndyke, "and we haven't done so badly, considering that this is only the beginning of our investigation. Have a look at the specimens and see if you agree with the findings."
I went over to the microscope bench and ran my eye over the exhibits. As I did so, I was once more impressed by the wonderfully simple, orderly and efficient plan on which my colleague worked. For years past, indeed, from the very earliest days of his practice, it had been his habit to collect impartially examples of every kind of natural and artificial material and to make, wherever it was practicable, permanent microscopic preparations of each. The result was an immense and carefully classified collection of minute objects of all kinds—hairs, feathers, insect scales, diatoms, pollen, seeds, powders, starches, textiles, threads, fibres—any one of which could be found in a moment and used for comparison with any new "find," the nature of which had to be determined. Thus he was, to a great extent, independent of books of reference and had the great advantage of being able to submit both the new specimen and the "standard" to any kind of test with the micrometer or polariscope or otherwise.
In the present case, the specimens were laid out in pairs, the new, unknown specimen with a "certified" example from the collection; and an eye-piece micrometer was in position for comparing dimensions. I took up one slide, labelled "E. H. decd. 15. 7. 03. From Rt. Bronchus," and placed it on the stage of the microscope. Instantly the nature of the object became obvious. It was a fish-scale; but, of course, I could not say what fish. Then I laid on the stage the companion slide from the collection, labelled "Scale of Herring," and made a rough comparison. In the shape of the margins, the concentric and radiating markings and all other characters, the two specimens appeared to be identical. I did not make an exhaustive examination, assuming that this had been done by Thorndyke, but went on to the other specimens. All the fish-scales were alike, as might have been expected, and I gave them only a passing glance. Then I picked up a slide labelled "From Trachcea" and placed it on the stage. The specimen appeared to be a small piece of a leaf of some kind; a rather large leaf, as I judged by the absence of any indication of form, and by its thickness, and I observed that it seemed to have one cut edge.
