which he placed on the ledge before him. Hewitt raised his hand to enjoin silence. The man spoke in a rather high-pitched voice and with a slight accent. “Is Mr. Dixon now within?” he asked.
“He is engaged,” answered one of the draughtsmen; “very particularly engaged. I am afraid you won’t be able to see him this afternoon. Can I give him any message?”
“This is two—the second time I have come to-day. Not two hours ago Mr. Dixon himself tells me to call again. I have a very important—very excellent steam-packing to show him that is very cheap and the best of the market.” The man tapped his bag. “I have just taken orders from the largest railway companies. Can not I see him, for one second only? I will not detain him.”
“Really, I’m sure you can’t this afternoon; he isn’t seeing anybody. But if you’ll leave your name—”
“My name is Hunter; but what the good of that? He ask me to call a little later, and I come, and now he is engaged. It is a very great pity.” And the man snatched up his bag and walking-stick, and stalked off, indignantly.
Hewitt stood still, gazing through the small aperture in the doorway.
“You’d scarcely expect a man with such a name as Hunter to talk with that accent, would you?” he observed, musingly. “It isn’t a French accent, nor a German; but it seems foreign. You don’t happen to know him, I suppose?”
“No, I don’t. He called here about half-past twelve, just while we were in the middle of our search and I was frantic over the loss of the drawings. I was in the outer office myself, and told him to call later. I have lots of such agents here, anxious to sell all sorts of engineering appliances. But what will you do now? Shall you see my men?”
“I think,” said Hewitt, rising—“I think I’ll get you to question them yourself.”
“Myself?”
“Yes, I have a reason. Will you trust me with the ‘key’ of the private room opposite? I will go over there for a little, while you talk to your men in this room. Bring them in here and shut the door; I can look after the office from across the corridor, you know. Ask them each to detail his exact movements about the office this morning, and get them to recall each visitor who has been here from the beginning of the week. I’ll let you know the reason of this later. Come across to me in a few minutes.”
Hewitt took the key and passed through the outer office into the corridor.
Ten minutes later Mr. Dixon, having questioned his draughtsmen, followed him. He found Hewitt standing before the table in the private room, on which lay several drawings on tracing-paper.
“See here, Mr. Dixon,” said Hewitt, “I think these are the drawings you are anxious about?”
The engineer sprang toward them with a cry of delight. “Why, yes, yes,” he exclaimed, turning them over, “every one of them! But where—how—they must have been in the place after all, then? What a fool I have been!”
Hewitt shook his head. “I’m afraid you’re not quite so lucky as you think, Mr. Dixon,” he said. “These drawings have most certainly been out of the house for a little while. Never mind how—we’ll talk of that after. There is no time to lose. Tell me—how long would it take a good draughtsman to copy them?”
“They couldn’t possibly be traced over properly in less than two or two and a half long days of very hard work,” Dixon replied with eagerness.
“Ah! then it is as I feared. These tracings have been photographed, Mr. Dixon, and our task is one of every possible difficulty. If they had been copied in the ordinary way, one might hope to get hold of the copy. But photography upsets everything. Copies can be multiplied with such amazing facility that, once the thief gets a decent start, it is almost hopeless to checkmate him. The only chance is to get at the negatives before copies are taken. I must act at once; and I fear, between ourselves, it may be necessary for me to step very distinctly over the line of the law in the matter. You see, to get at those negatives may involve something very like house-breaking. There must be no delay, no waiting for legal procedure, or the mischief is done. Indeed, I very much question whether you have any legal remedy, strictly speaking.”
“Mr. Hewitt, I implore you, do what you can. I need not say that all I have is at your disposal. I will guarantee to hold you harmless for anything that may happen. But do, I entreat you, do everything possible. Think of what the consequences may be!”
“Well, yes, so I do,” Hewitt remarked, with a smile. “The consequences to me, if I were charged with house-breaking, might be something that no amount of guarantee could mitigate. However, I will do what I can, if only from patriotic motives. Now, I must see your tracer, Ritter. He is the traitor in the camp.”
“Ritter? But how?”
“Never mind that now. You are upset and agitated, and had better not know more than is necessary for a little while, in case you say or do something unguarded. With Ritter I must take a deep course; what I don’t know I must appear to know, and that will seem more likely to him if I disclaim acquaintance with what I do know. But first put these tracings safely away out of sight.”
Dixon slipped them behind his book-case.
“Now,” Hewitt pursued, “call Mr. Worsfold and give him something to do that will keep him in the inner office across the way, and tell him to send Ritter here.”
Mr. Dixon called his chief draughtsman and requested him to put in order the drawings in the drawers of the inner room that had been disarranged by the search, and to send Ritter, as Hewitt had suggested.
Ritter walked into the private room with an air of respectful attention. He was a puffy-faced, unhealthy-looking young man, with very small eyes and a loose, mobile mouth.
“Sit down, Mr. Ritter,” Hewitt said, in a stern voice. “Your recent transactions with your friend Mr. Hunter are well known both to Mr. Dixon and myself.”
Ritter, who had at first leaned easily back in his chair, started forward at this, and paled.
“You are surprised, I observe; but you should be more careful in your movements out of doors if you do not wish your acquaintances to be known. Mr. Hunter, I believe, has the drawings which Mr. Dixon has lost, and, if so, I am certain that you have given them to him. That, you know, is theft, for which the law provides a severe penalty.”
Ritter broke down completely and turned appealingly to Mr. Dixon.
“Oh, sir,” he pleaded, “it isn’t so bad, I assure you. I was tempted, I confess, and hid the drawings; but they are still in the office, and I can give them to you—really, I can.”
“Indeed?” Hewitt went on. “Then, in that case, perhaps you’d better get them at once. Just go and fetch them in; we won’t trouble to observe your hiding-place. I’ll only keep this door open, to be sure you don’t lose your way, you know—down the stairs, for instance.”
The wretched Ritter, with hanging head, slunk into the office opposite. Presently he reappeared, looking, if possible, ghastlier than before. He looked irresolutely down the corridor, as if meditating a run for it, but Hewitt stepped toward
