"We found the man Riggs lying as Rose had said. He was quite dead, cold and stiff. There was a pistol wound on the right temple, and a pistol lay on the floor at his right side. A little blood—but not much—had trickled from the wound and lay in a small pool on the oilcloth. The door of an iron safe was open and a bunch of keys hung from the lock; and on a desk one or two share certificates were spread out. On searching the dead man's pockets it was found that the gold watch which the servant told us he usually carried was missing, and when Rose went to the bedroom to see if it was there, it was nowhere to be found.
"Apart from the watch, however, the appearances suggested that the man had taken his own life. But against this view was the blood on the hall floor. The dead man appeared to have fallen at once from the effects of the shot, and there had been very little bleeding. Then how came the blood in the hall? The inspector decided that it could not have been the blood of the deceased; and when we examined it and saw that there were several little pools and that they seemed to form a track towards the street door, he was convinced that the blood had fallen from some person who had been wounded and was escaping from the house. And, under the circumstances, he was bound to assume that that person was Robert Fletcher; and on that assumption, he dispatched the sergeant forthwith to arrest Robert.
"On this I held a consultation with Mr. Brodribb, who pointed out that the case turned principally on the blood in the hall. If it was the blood of deceased, and the absence of the watch could be explained, a verdict of suicide could be accepted. But if it was the blood of some other person, that fact would point to murder. The question, he said, would have to be settled, if possible, and his advice to me, if I believed Robert to be innocent—which, from my knowledge of him, I certainly did—was this: Get a couple of small, clean, labelled bottles from a chemist and—with the inspector's consent—put in one a little of the blood from the hall and in the other some of the blood of the deceased. Seal them both in the inspector's presence and mine and take them up to Dr. Thorndyke. If it is possible to answer the question, Are they or are they not from the same person? he will answer it.
"Well, the inspector made no objection, so I did what he advised. And here are the specimens. I trust they may tell us what we want to know."
Here Mr. Foxley took from his attaché-case a small cardboard box, and opening it, displayed two little wide-mouthed bottles carefully packed in cotton wool. Lifting them out tenderly, he placed them on the table before Thorndyke. They were both neatly corked, sealed—with Brodribb's seal, as I noticed—and labelled; the one inscribed "Blood of Joseph Riggs," and the other "Blood of unknown origin," and both signed "Arthur Foxley" and dated. At the bottom of each was a small mass of gelatinous blood-clot.
Thorndyke looked a little dubiously at the two bottles, and addressing the clergyman, said: "I am afraid Mr. Brodribb has rather over-estimated our resources. There is no known method by which the blood of one person can be distinguished with certainty from that of another."
"Dear, dear!" exclaimed Mr. Foxley. "How disappointing! Then these specimens are useless, after all?"
"I won't say that; but it is in the highest degree improbable that they will yield any information. You must build no expectations on them."
"But you will examine them and see if anything is to be gleaned," the parson urged, persuasively.
"Yes, I will examine them. But you realise that if they should yield any evidence, that evidence might be unfavourable?"
"Yes; Mr. Brodribb pointed that out, but we are willing to take the risk, and so, I may say, is Robert Fletcher, to whom I put the question."
"Then you have seen Mr. Fletcher since the discovery?"
"Yes, I saw him at the police station after his arrest. It was then that he gave me—and also the police—the particulars that I have repeated to you. He had to make a statement, as the dead man's watch and the bonds were found in his possession."
"With regard to the pistol. Has it been identified?"
"No. It is an old-fashioned derringer which no one has ever seen before, so there is no evidence as to whose property it was."
"And as to those share certificates which you spoke of as lying on the desk. Do you happen to remember what they were?"
"Yes, they were West African mining shares; Abusum Pa-pa was the name, I think."
"Then," said Thorndyke,"Mr. Riggs had been losing money. The Abusum Pa-pa Company has just gone into liquidation. Do you know if anything had been taken from the safe?"
"It is impossible to say, but apparently not, as there was a good deal of money in the cash-box, which we unlocked and inspected. But we shall hear more to-morrow at the inquest, and I trust we shall hear something there from you. But in any case I hope you will attend to watch the proceedings on behalf of poor Fletcher. And if possible, to be present at the autopsy at eleven o'clock. Can you manage that?"
"Yes. And I shall come down early enough to make an inspection of the premises if the police will give the necessary facilities."
Mr. Foxley thanked him effusively, and when the details as to the trains had been arranged, our clients rose to depart. Thorndyke shook their hands cordially, and as he bade farewell to Miss Markham he murmured a few words of encouragement. She looked up at him gratefully and appealingly as she naïvely held his hand.
"You will try to help us, Dr. Thorndyke, won't you?" she urged. "And you will examine that blood very, very carefully. Promise that you will. Remember that poor Robert's life may hang upon what you can tell about it."
"I realise that, Miss Markham," he replied gently, "and I promise you that the specimens shall be most thoroughly examined; and further, that no stone shall be left unturned in my endeavours to bring the truth to light."
At his answer, spoken with infinite kindliness and sympathy, her eyes filled and she turned away with a few broken words of thanks, and the good clergyman—himself not unmoved by the little episode—took her arm and led her to the door.
"Well," I remarked as their retreating footsteps died away, "old Brodribb's enthusiasm seems to have let you in for a queer sort of task; and I notice that you appear to have accepted Fletcher's statement."
"Without prejudice," he replied. "I don't know Fletcher, but the balance of probabilities is in his favour. Still, that blood-track in the hall is a curious feature. It certainly requires explanation."
"It does, indeed!" I exclaimed, "and you have got to find the explanation! Well, I wish you joy of the job. I suppose you will carry out the farce to the bitter end as you have promised? "
"Certainly," he replied. "But it is hardly a farce. I should have looked the specimens over in any case. One never knows what illuminating fact a chance observation may bring into view."
I smiled sceptically.
"The fact that you are asked to ascertain is that these two samples of blood came from the same person. If there are any means of proving that, they are unknown to me. I should have said it was an impossibility."
"Of course," he rejoined, "you are quite right, speaking academically and in general terms. No method of identifying the blood of individual persons has hitherto been discovered. But yet I can imagine the possibility, in particular and exceptional cases, of an actual, personal identification by means of blood. What does my learned friend think?"
"He thinks that his imagination is not equal to the required effort," I answered; and with that I picked up my brief-bag and went forth to my duties at the courts.
That Thorndyke would keep his promise to poor Lilian Markham was a foregone conclusion, preposterous as the examination seemed. But even my long experience of my colleague's scrupulous conscientiousness had not prepared me for the spectacle which met my eyes when I returned to our chambers. On the table stood the microscope, flanked by three slide-boxes. Each box held six trays, and each tray held six slides—a hundred and eight slides in all!
But why three boxes? I opened one. The slides—carefully mounted blood-films—were labelled "Joseph Riggs." Those in t
he second box were labelled," Blood from hall floor." But when I opened the third box, I beheld a collection of empty slides labelled "Robert Fletcher"!
I chuckled aloud. Prodigious! Thorndyke was going even one better than his promise. He was not only going to examine—probably had examined—the two samples produced; he was actually going to collect a third sample for himself!
I picked out one of Mr. Riggs's slides and laid it on the stage of the microscope. Thorndyke seemed to have been using a low-power objective—the inch-and-a-half. After a glance through this, I swung round the nose-piece to the high power. And then I got a further surprise. The brightly-coloured "white" corpuscles showed that Thorndyke had actually been to the trouble of staining the films with eosin! Again I murmured, "Prodigious!" and put the slide back in its box. For, of course, it showed just what one expected: blood—or rather, broken-up blood-clot. From its appearance I could not even have sworn that it was human blood.
I had just closed the box when Thorndyke entered the room. His quick eye at once noted the changed objective and he remarked: "I see you have been having a look at the specimens."
"A specimen." I corrected. "Enough is as good as a feast."
"Blessed are they who are easily satisfied," be retorted; and then he added: "I have altered my arrangements, though I needn't interfere with yours. I shall go down to Southaven to-night; in fact, I am starting in a few minutes."
"Why?" I asked.
"For several reasons. I want to make sure of the post-mortem tomorrow morning, I want to pick up any further facts that are available, and finally, I want to prepare a set of blood-films from Robert Fletcher. We may as well make the series complete," he added with a smile, to which I replied by a broad grin.
"Really, Thorndyke," I protested. "I'm surprised at you, at your age, too. She is a nice girl, but she isn't so beautiful as to justify a hundred and eight blood-films."
I accompanied him to the taxi, followed by Polton, who carried his modest luggage, and then returned to speculate on his probable plan of campaign. For, of course, he had one. His purposive, resolute manner told me that he had seen farther into this case than I had. I accepted that as natural and inevitable. Indeed, I may admit that my disrespectful badinage covered a belief in his powers hardly second even to old Brodribb's. I was, in fact, almost prepared to discover that those preposterous blood-films had, after all, yielded some "illuminating fact" which had sent him hurrying down to Southaven in search of corroboration.
When I alighted from the train on the following day at a little past noon, I found him waiting on the platform, ready to conduct me to his hotel for an early lunch.
"All goes well, so far," he reported. "I attended the post-mortem, and examined the wound thoroughly. The pistol was held in the right hand not more than two inches from the head; probably quite close, for the skin is scorched and heavily tattooed with black powder grains. I find that Riggs was right-handed. So the prima facie probabilities are in favour of suicide; and the recent loss of money suggests a reasonable motive."
"But what about that blood in the hall?"
"Oh, we have disposed of that. I completed the blood-film series last night."
I looked at him quickly to see if he was serious or only playing a facetious return-shot. But his face was as a face of wood.
"You are an exasperating old devil, Thorndyke!" I exclaimed with conviction. Then, knowing that cross-examination would be futile, I asked: "What are we going to do after lunch?"
"The inspector is going to show us over 'the scene of the tragedy,' as the newspapers would express it."
I noted gratefully that he had reserved this item for me, and dismissed professional topics for the time being, concentrating my attention on the old-world, amphibious streets through which we were walking. There is always something interesting in the aspect of a sea-port town, even if it is only a small one like Southaven.
The inspector arrived with such punctuality that he found us still at the table and was easily induced to join us with a cup of coffee and to accept a cigar—administered by Thorndyke, as I suspected, with the object of hindering conversation. I could see that his interest in my colleague was intense and not unmingled with awe, a fact which, in conjunction with the cigar, restrained him from any undue manifestations of curiosity, but not from continuous, though furtive, observation of my friend. Indeed, when we arrived at the late Mr. Riggs's house, I was secretly amused by the close watch that he kept on Thorndyke's movements, unsensational as the inspection turned out to be.
The house, itself, presented very little of interest excepting its picturesque old-world exterior, which fronted on a quiet by-street and was furnished with a deep bay which, as Thorndyke ascertained, commanded a clear view of the street from end to end. It was a rather shabby, neglected little house, as might have been expected, and our examination of it yielded, so far as I could see, only a single fact of any significance: which was that there appeared to be no connection what ever between the blood-stain on the study floor and the train of large spots from the middle of the hall to the street door. And on this piece of evidence—definitely unfavourable from our point of view—Thorndyke concentrated his attention when he had made a preliminary survey.
Closely followed by the watchful inspector, he browsed round the little room, studying every inch of the floor between the blood-stain and the door. The latter he examined minutely from top to bottom, especially as to the handle, the jambs, and the lintel. Then he went out into the hall, scrutinising the floor inch by inch, poring over the walls, and even looking behind the framed prints that hung on them. A reflector lamp suspended by a nail on the wall received minute and prolonged attention, as did also a massive lamp-hook screwed into one of the beams of the low ceiling, of which Thorndyke remarked as he stooped to pass under it, that it must have been fixed there by a dwarf.
"Yes," the inspector agreed, "and a fool. A swinging lamp hung on that hook would have blocked the whole fairway. There isn't too much room as it is. What a pity we weren't a bit more careful about footprints in this place. There are plenty of tracks of wet feet here on this oil-cloth; faint, but you could have made them out all right if they hadn't been all on top of one another. There's Mr. Foxley's, the girl's, mine, and the men who carried out the body, but I'm hanged if I can tell which is which. It's a regular mix up."
"Yes," I agreed, "it is all very confused. But I notice one rather odd thing. There are several faint traces of a large right foot, but I can't see any sign of the corresponding left foot. Can you?"
"Perhaps this is it," said Thorndyke, pointing to a large, vague oval mark. "I have noticed that it seems to occur in some sort of connection with the big right foot; but I must admit that it is not a very obvious foot-print."
"I shouldn't have taken it for a foot-print at all, or at any rate, not a human foot-print. It is more like the spoor of some big animal."
"It is," Thorndyke agreed; "but whatever it is, it seems to have been here before any of the others arrived. You notice that wherever it occurs, it seems to have been trodden on by some of the others."
"Yes, I had noticed that, and the same is true of the big right foot, so it seems probable that they are connected, as you say. But I am hanged if I can make anything of it. Can you, inspector?"
The inspector shook his head. He could not recognise the mark as a foot-print, but he could see very plainly that he had been a fool not to have taken more care to protect the floor.
When the examination of the hall was finished, Thorndyke opened the door and looked at the big, flat doorstep. "What was the weather like here on Wednesday evening?" he asked.
"Showery," the inspector replied; "and there were one or two heavy showers during the night. You were noticing that there are no blood-tracks on the doorstep. But there wouldn't be in any case; for if a man had come out of this door dropping blood, the blood would have dropped on wet stone and got washed away at once."
Thorndyke admitted the truth of this; and so an
other item of favourable evidence was extinguished. The probability that the blood in the hall was that of some person other than the deceased remained undisturbed; and I could not see that a single fact had been elicited by our inspection of the house that was in any way helpful to our client. Indeed, it appeared to me that there was absolutely no case for the defence, and I even asked myself whether we were not, in fact, merely trying to fudge up a defence for an obviously guilty man. It was not like Thorndyke to do that. But how did the case stand? There was a suggestion of suicide, but a clear possibility of homicide. There was strong evidence that a second person had been in the house, and that person appeared to have received a wound. But a wound suggested a struggle; and the servant's evidence was to the effect that when she left the house a violent altercation was in progress. The deceased was never again seen alive; and the other party to the quarrel had been found with property of the dead man in his possession. Moreover, there was a clear motive for the crime, stupid as that crime was. For the dead man had threatened to revoke his will but as he had presumably not done so, his death left the will still operative. In short, everything pointed to the guilt of our client, Robert Fletcher.
I had just reached this not very gratifying conclusion when a statement of Thorndyke's shattered my elaborate summing up into impalpable fragments.
"I suppose, sir," said the inspector, "there isn't anything that you would care to tell us, as you are for the defence. But we are not hostile to Fletcher. In fact, he hasn't been charged. He is only being detained in custody until we have heard what turns up at the inquest. I know you have examined that blood that Mr. Foxley took, and Fletcher's blood, too, and you've seen the premises. We have given all the facilities that we could, and if you could give us any sort of hint that might be useful, I should be very much obliged."
Thorndyke reflected for a few moments. Then he replied: "There is no reason for secrecy in regard to you, inspector, who have been so helpful and friendly, so I will be quite frank. I have examined both samples of blood and Fletcher's, and I have inspected the premises; and what I am able to say definitely is this: the blood in the hall is not the blood of the deceased—"
