“This,” asked Hewitt, “was not in the room that Mrs. Heath had occupied, I take it?”

“No; this was in another part of the building.  Well, the brooch went—­taken, evidently, by some one in a deuce of a hurry, for, when Mrs. Armitage got back to her room, there was the pin-cushion with a little tear in it, where the brooch had been simply snatched off.  But the curious thing was that the ring—­worth a dozen of the brooch—­was left where it had been put.  Mrs. Armitage didn’t remember whether or not she had locked the door herself, although she found it locked when she returned; but my niece, who was indoors all the time, went and tried it once—­because she remembered that a gas-fitter was at work on the landing near by—­and found it safely locked.  The gas-fitter, whom we didn’t know at the time, but who since seems to be quite an honest fellow, was ready to swear that nobody but my niece had been to the door while he was in sight of it—­which was almost all the time.  As to the window, the sash-line had broken that very morning, and Mrs. Armitage had propped open the bottom half about eight or ten inches with a brush; and, when she returned, that brush, sash, and all were exactly as she had left them.  Now I scarcely need tell you what an awkward job it must have been for anybody to get noiselessly in at that unsupported window; and how unlikely he would have been to replace it, with the brush, exactly as he found it.”

“Just so.  I suppose the brooch, was really gone?  I mean, there was no chance of Mrs. Armitage having mislaid it?”

“Oh, none at all!  There was a most careful search.”

“Then, as to getting in at the window, would it have been easy?”

“Well, yes,” Sir James replied; “yes, perhaps it would.  It was a first-floor window, and it looks over the roof and skylight of the billiard-room.  I built the billiard-room myself—­built it out from a smoking-room just at this corner.  It would be easy enough to get at the window from the billiard-room roof.  But, then,” he added, “that couldn’t have been the way.  Somebody or other was in the billiard-room the whole time, and nobody could have got over the roof (which is nearly all skylight) without being seen and heard.  I was there myself for an hour or two, taking a little practice.”

“Well, was anything done?”

“Strict inquiry was made among the servants, of course, but nothing came of it.  It was such a small matter that Mrs. Armitage wouldn’t hear of my calling in the police or anything of that sort, although I felt pretty certain that there must be a dishonest servant about somewhere.  A servant might take a plain brooch, you know, who would feel afraid of a valuable ring, the loss of which would be made a greater matter of.”

“Well, yes, perhaps so, in the case of an inexperienced thief, who also would be likely to snatch up whatever she took in a hurry.  But I’m doubtful.  What made you connect these two robberies together?”
