"You can depend on me to do my best, sir," said Miller, "though I am working rather in the dark. I suppose you couldn't give me any sort of hint as to what you've got up your sleeve. You've no doubt, for instance, that it was really the man Samway who committed this murder?"
Thorndyke, according to his usual habit, considered the Superintendent's question for awhile before answering. At length he replied: "I don't know why I shouldn't take you into my confidence to some extent, Miller, knowing you as I do. But you will remember that this is a confidence. The fact is that I am proposing to proceed against this man on an entirely different charge. But I am not quite ready to lay an information; and I want you to secure his person on the charge of murdering his wife while I complete the other case."
"Is that another case of murder?" asked Miller.
"Yes. The facts are briefly these. A certain Septimus Maddock, who was living with the Samways, died some time ago under what seem to me very suspicious circumstances. He was nursed by Samway and his wife and by no one else. The cause of death given on the certificate was, in my opinion, not the true one, and I am proceeding to verify my theory as to what was the real cause of death."
"I see," said Miller. "You are applying for an exhumation of the body?"
"Well, hardly an exhumation. The man Maddock was cremated."
"Cremated!" exclaimed Miller. "Then we've done. There isn't any body to exhume."
"No," agreed Thorndyke, " there is no body, but there are the ashes."
"But, surely," said Miller, " you can't get any information out of a few handfuls of bone ash?"
"That remains to be proved," replied Thorndyke. "I have applied for an authority to make an exhaustive examination of those ashes, and, if my opinion as to the cause of death is correct, I shall be able to demonstrate its correctness; and that will involve a charge of murder against this man Samway. It will also support a charge against him of attempts to murder Dr. Jardine, and furnish strong evidence connecting him with the horrible crime that has just been committed. So you see, Miller, that the important thing is to get possession of him before he has time to escape from this country, and hold him in custody, if necessary, while the evidence against him is being examined and completed. And I must impress on you that no time ought to be lost in getting the description circulated."
"No, that's true," said Miller. "I'll go and telegraph it off at once, and I'll send one or two of our best men to watch the likely seaports."
He shook hands with us all round, and, when we had all most fervently wished him success he took his departure.
As soon as he was gone, Jervis turned to his senior, and, looking at him with a sort of puzzled curiosity exclaimed: "You are a most astounding person, Thorndyke! You really are! I thought I had begun to see daylight in that Maddock case, and now I find that I was all abroad. And I can't, for the life of me, conceive what in the world you expect to discover by examining a few pounds of calcined phosphates. Suppose Maddock was poisoned, what evidence will be obtainable from the ashes? Of the poisons which could possibly have been used under the known circumstances, not one would leave a trace after cremation. But, of course, you've thought of all that."
"Certainly, I have," replied Thorndyke, " and I agree with you that the ashes of a body that has been cremated are highly unpromising material for a primary investigation. But, does it not occur to you that, in a case where certain circumstantial evidence is available, excellent corroborative data might be obtained by the examination of the ashes?"
"No," replied Jervis, "I can't say that it does."
"It is not too late to consider the question," said Thorndyke. "I shall probably not get the authority for a day or two, so you will have time to turn the problem over in the interval. It is quite worth your while, I assure you, apart from this particular case, as a mere exercise in constructive theory. You can acquire experience from imaginary cases as well as from real ones, as I have often pointed out; in fact, much of my own experience has been gained in this way. I think I have mentioned to you that, in my early days, when I had more leisure than practice, it was my custom to construct imaginary crimes of an elaborately skilful type, and then—having, of course, all the facts—to consider the appropriate procedure for their detection. It was a most valuable exercise, for I was thus able to furnish myself with an abundance of problems of a kind that, in actual practice, are met with only at long intervals of years. And since then a quite considerable number of my imaginary cases have presented themselves, in a more or less modified form, for solution in the course of practice, and have come to me with the familiarity of problems that have already been considered and solved. That is what you should do, Jervis. Try the synthetic method and then consider what analytical procedure would be appropriate to your result."
"I have," Jervis replied, gloomily. "I have worked at this confounded case until I feel like a rat that has been trying to gnaw through a plate-glass window. Still, I'll have another try. By the way, where are you going to make this examination?"
"I think I shall do it here. I had thought of handing the ashes over to one of the more eminent analysts, but it will be only a small operation, well within the capacity of our own laboratory. I think of asking Professor Woodfield to come here and carry out the actual analysis. Polton will give him any help that he may want and, of course, we shall be here to give any further assistance if he should need it."
"Why not have made the analysis yourself?" asked Jervis. "Is there anything specially difficult or intricate about it?"
"Not at all," replied Thorndyke. "But, as the case will have to go into Court on a capital charge—that is, assuming that my hypothesis turns out to be correct—I thought it best to have the analysis made by a man whose name as an authority on chemistry will carry special weight. Neither the judge nor the jury are likely to have much special knowledge of chemistry, but they will be able to appreciate the fact that Woodfield is a man with a world-wide reputation, and they will respect his opinion accordingly."
"Yes," agreed Jervis, "I think you are quite right. A well-known name goes a long way with a jury. I hope your experiment will turn out as you expect, and I hope, too, that some of Miller's men will manage to lay that murderous devil by the heels. But I'm afraid they'll have their work cut out. He is a clever scoundrel; one must admit that. How do you suppose he contrived to track Jardine here?"
"I think," replied Thorndyke, "that he must have seen us on one of the two occasions when we went to the mineral water works and followed us here. Then, when Jardine disappeared from his lodgings, he would naturally look for him here, this being, in fact, the only place known to him in connection with Jardine, excepting Batson's house, on which he also probably kept a watch."
"But how would he have discovered that Jardine actually was here?"
"There are a number of ways in which he might have ascertained the fact. A good many persons knew that we had a new resident. We could not conceal his presence here. Many of our visitors have seen him, and the porter and hangers-on of the inn will have noticed him taking his exercise in the morning. Samway, himself, even, may have seen him, and he would easily have penetrated the disguise if he saw him out of doors, for there is no disguising a man's stature. He might have made enquiries of one of the porters or lamp-lighters, or he might have employed someone else to make enquiries. The fact that someone was staying here and that his name was Howard could not have been very difficult to discover, while, as for ourselves, we are as well known in the inn as the griffin at Temple Bar. From the circumstance that he knew of our attendance at the Maidstone Assizes, it seems likely that he had subsidized some solicitor's clerk who would know our movements."
"And I suppose," said I, " as he is gone now, I may as well go back to my lodgings."
"Not
