This exposition of Thorndyke's proposed conduct of the case, reasonable as it was, did not impress me as very convincing. I found myself coming back to Marchmont's position, that there was really nothing in dispute. But other matters claimed our attention at the moment, and it was not until after dinner that my colleague reverted to the subject.
"How should you like to take a turn round to New Inn this evening?" he asked.
"I should have thought," said I, "that it would be better to go by daylight. Those old chambers are not usually very well illuminated."
"That is well thought of," said Thorndyke. "We had better take a lamp with us. Let us go up to the laboratory and get one from Polton."
"There is no need to do that," said I. "The pocket-lamp that you lent me is in my overcoat pocket. I put it there to return it to you."
"Did you have occasion to use it?" he asked.
"Yes. I paid another visit to the mysterious house and carried out your plan. I must tell you about it later."
"Do. I shall be keenly interested to hear all about your adventures. Is there plenty of candle left in the lamp?"
"Oh yes. I only used it for about an hour."
"Then let us be off," said Thorndyke; and we accordingly set forth on our quest; and, as we went, I reflected once more on the apparent vagueness of our proceedings. Presently I reopened the subject with Thorndyke.
"I can't imagine," said I, "that you have absolutely nothing in view. That you are going to this place with no defined purpose whatever."
"I did not say exactly that," replied Thorndyke. "I said that I was not going to look for any particular thing or fact. I am going in the hope that I may observe something that may start a new train of speculation. But that is not all. You know that an investigation follows a certain logical course. It begins with the observation of the conspicuous facts. We have done that. The facts were supplied by Marchmont. The next stage is to propose to oneself one or more provisional explanations or hypotheses. We have done that, too—or, at least I have, and I suppose you have."
"I haven't," said I. "There is Jeffrey's will, but why he should have made the change I cannot form the foggiest idea. But I should like to hear your provisional theories on the subject."
"You won't hear them at present. They are mere wild conjectures. But to resume: what do we do next?"
"Go to New Inn and rake over the deceased gentleman's apartments."
Thorndyke smilingly ignored my answer and continued—
"We examine each explanation in turn and see what follows from it; whether it agrees with all the facts and leads to the discovery of new ones, or, on the other hand, disagrees with some facts or leads us to an absurdity. Let us take a simple example.
"Suppose we find scattered over a field a number of largish masses of stone, which are entirely different in character from the rocks found in the neighbourhood. The question arises, how did those stones get into that field? Three explanations are proposed. One: that they are the products of former volcanic action; two: that they were brought from a distance by human agency; three: that they were carried thither from some distant country by icebergs. Now each of those explanations involves certain consequences. If the stones are volcanic, then they were once in a state of fusion. But we find that they are unaltered limestone and contain fossils. Then they are not volcanic. If they were borne by icebergs, then they were once part of a glacier and some of them will probably show the flat surfaces with parallel scratches which are found on glacier-borne stones. We examine them and find the characteristic scratched surfaces. Then they have probably been brought to this place by icebergs. But this does not exclude human agency, for they might have been brought by men to this place from some other where the icebergs had deposited them. A further comparison with other facts would be needed.
"So we proceed in cases like this present one. Of the facts that are known to us we invent certain explanations. From each of those explanations we deduce consequences; and if those consequences agree with new facts, they confirm the explanation, whereas if they disagree they tend to disprove it. But here we are at our destination."
We turned out of Wych Street into the arched passage leading into New Inn, and, halting at the half-door of the lodge, perceived a stout, purple-faced man crouching over the fire, coughing violently. He held up his hand to intimate that he was fully occupied for the moment, and we accordingly waited for his paroxysm to subside. At length he turned towards us, wiping his eyes, and inquired our business.
"Mr. Stephen Blackmore," said Thorndyke, "has given me permission to look over his chambers. He said that he would mention the matter to you."
"So he has, sir," said the porter; "but he has just taken the key himself to go to the chambers. If you walk across the Inn you'll find him there; it's on the farther side; number thirty-one, second floor."
We made our way across to the house indicated, the ground floor of which was occupied by a solicitor's offices and was distinguished by a good-sized brass plate. Although it had now been dark some time there was no light on the lower stairs, but we encountered on the first-floor landing a man who had just lit the lamp there. Thorndyke halted to address him.
"Can you tell me who occupies the chambers on the third floor?"
"The third floor has been empty about three months," was the reply.
"We are going up to look at the chambers on the second floor," said Thorndyke. "Are they pretty quiet?"
"Quiet!" exclaimed the man. "Lord bless you the place is like a cemetery for the deaf and dumb. There's the solicitors on the ground floor and the architects on the first floor. They both clear out about six, and when they're gone the house is as empty as a blown hegg. I don't wonder poor Mr. Blackmore made away with his-self. Livin' up there all alone, it must have been like Robinson Crusoe without no man Friday and not even a blooming goat to talk to. Quiet! It's quiet enough, if that's what you want. Wouldn't be no good to me."
With a contemptuous shake of the head, he turned and retired down the next flight, and, as the echoes of his footsteps died away we resumed our ascent.
"So it would appear," Thorndyke commented, "that when Jeffrey Blackmore came home that last evening, the house was empty."
Arrived on the second-floor landing, we were confronted by a solid-looking door on the lintel of which the deceased man's name was painted in white lettering which still looked new and fresh. Thorndyke knocked at the door, which was at once opened by Stephen Blackmore.
"I haven't wasted any time before taking advantage of your permission, you see," my colleague said as we entered.
"No, indeed," said Stephen; "you are very prompt. I have been rather wondering what kind СКАЧАТЬ
