He inserted the key into the wicket of the large gate, and, when we had stepped through into the covered way, he locked it from the inside.
"Why have you locked us in?" I asked, seeing that the wicket had a latch.
"Because," he replied, "if we now hear any one on the premises we shall know who it is. Only one person besides ourselves has a key."
His reply startled me somewhat. I stopped and looked at him.
"That is a quaint situation, Thorndyke. I hadn't thought of it. Why she may actually come to the house while we are here; in fact, she may be in the house at this moment."
"I hope not," said he. "We don't particularly want Mr. Weiss to be put on his guard, for I take it, he is a pretty wide-awake gentleman under any circumstances. If she does come, we had better keep out of sight. I think we will look over the house first. That is of the most interest to us. If the lady does happen to come while we are here, she may stay to show us over the place and keep an eye on us. So we will leave the stables to the last."
We walked down the entry to the side door at which I had been admitted by Mrs. Schallibaum on the occasion of my previous visits. Thorndyke inserted the latch-key, and, as soon as we were inside, shut the door and walked quickly through into the hall, whither I followed him. He made straight for the front door, where, having slipped up the catch of the lock, he began very attentively to examine the letter-box. It was a somewhat massive wooden box, fitted with a lock of good quality and furnished with a wire grille through which one could inspect the interior.
"We are in luck, Jervis," Thorndyke remarked. "Our visit has been most happily timed. There is a letter in the box."
"Well," I said, "we can't get it out; and if we could, it would be hardly justifiable."
"I don't know," he replied, "that I am prepared to assent off-hand to either of those propositions; but I would rather not tamper with another person's letter, even if that person should happen to be a murderer. Perhaps we can get the information we want from the outside of the envelope."
He produced from his pocket a little electric lamp fitted with a bull's-eye, and, pressing the button, threw a beam of light in through the grille. The letter was lying on the bottom of the box face upwards, so that the address could easily be read.
"Herrn Dr. H. Weiss," Thorndyke read aloud. "German stamp, postmark apparently Darmstadt. You notice that the 'Herrn Dr.' is printed and the rest written. What do you make of that?"
"I don't quite know. Do you think he is really a medical man?"
"Perhaps we had better finish our investigation, in case we are disturbed, and discuss the bearings of the facts afterwards. The name of the sender may be on the flap of the envelope. If it is not, I shall pick the lock and take out the letter. Have you got a probe about you?"
"Yes; by force of habit I am still carrying my pocket case."
I took the little case from my pocket and extracting from it a jointed probe of thickish silver wire, screwed the two halves together and handed the completed instrument to Thorndyke; who passed the slender rod through the grille and adroitly turned the letter over.
"Ha!" he exclaimed with deep satisfaction, as the light fell on the reverse of the envelope, "we are saved from the necessity of theft—or rather, unauthorized borrowing—'Johann Schnitzler, Darmstadt.' That is all that we actually want. The German police can do the rest if necessary."
He handed me back my probe, pocketed his lamp, released the catch of the lock on the door, and turned away along the dark, musty-smelling hall.
"Do you happen to know the name of Johann Schnitzler?" he asked.
I replied that I had no recollection of ever having heard the name before.
"Neither have I," said he; "but I think we may form a pretty shrewd guess as to his avocation. As you saw, the words 'Herrn Dr.' were printed on the envelope, leaving the rest of the address to be written by hand. The plain inference is that he is a person who habitually addresses letters to medical men, and as the style of the envelope and the lettering—which is printed, not embossed—is commercial, we may assume that he is engaged in some sort of trade. Now, what is a likely trade?"
"He might be an instrument maker or a drug manufacturer; more probably the latter, as there is an extensive drug and chemical industry in Germany, and as Mr. Weiss seemed to have more use for drugs than instruments."
"Yes, I think you are right; but we will look him up when we get home. And now we had better take a glance at the bedroom; that is, if you can remember which room it was."
"It was on the first floor," said I, "and the door by which I entered was just at the head of the stairs."
We ascended the two flights, and, as we reached the landing, I halted.
"This was the door," I said, and was about to turn the handle when Thorndyke caught me by the arm.
"One moment, Jervis," said he. "What do you make of this?"
He pointed to a spot near the bottom of the door where, on close inspection, four good-sized screw-holes were distinguishable. They had been neatly stopped with putty and covered with knotting, and were so nearly the colour of the grained and varnished woodwork as to be hardly visible.
"Evidently," I answered, "there has been a bolt there, though it seems a queer place to fix one."
"Not at all," replied Thorndyke. "If you look up you will see that there was another at the top of the door, and, as the lock is in the middle, they must have been highly effective. But there are one or two other points that strike one. First, you will notice that the bolts have been fixed on quite recently, for the paint that they covered is of the same grimy tint as that on the rest of the door. Next, they have been taken off, which, seeing that they could hardly have been worth the trouble of removal, seems to suggest that the person who fixed them considered that their presence might appear remarkable, while the screw-holes, which have been so skilfully and carefully stopped, would be less conspicuous.
"Then, they are on the outside of the door—an unusual situation for bedroom bolts—and were of considerable size. They were long and thick."
"I can see, by the position of the screw-holes, that they were long; but how do you arrive at their thickness?"
"By the size of the counter-holes in the jamb of the door. These holes have been very carefully filled with wooden plugs covered with knotting; but you can make out their diameter, which is that of the bolts, and which is decidedly out of proportion for an ordinary bedroom door. Let me show you a light."
He flashed his lamp into the dark corner, and I was able to see distinctly the portentously large holes into which the bolts had fitted, and also to note the remarkable neatness with which they had been plugged.
"There was a second door, I remember," said I. "Let us see if that was guarded in a similar manner."
We strode through the empty room, awakening dismal echoes as we trod the bare boards, and flung open the other door. At top and bottom, СКАЧАТЬ
