"When you left me in the smoking-room I compared the quill and the match very carefully, and found that the marks corresponded exactly. After this I felt very little doubt indeed. The fact of Lloyd having met the ladies walking before dark on the day of the first robbery proved nothing, because, since it was clear that the match had _not_ been used to procure a light, the robbery might as easily have taken place in daylight as not--must have so taken place, in fact, if my conjectures were right. That they were right I felt no doubt. There could be no other explanation. [Illustration: "EXPLAINING."] "When Mrs. Heath left her window open and her door shut, anybody climbing upon the open sash of Lloyd's high window could have put the bird upon the sill above. The match placed in the bird's beak for the purpose I have indicated and struck first, in case by accident it should ignite by rubbing against something and startle the bird--this match would, of course, be dropped just where the object to be removed was taken up; as you know, in every case the match was found almost upon the spot where the missing article had been left--scarcely a likely triple coincidence, had the match been used by a human thief. This would have been done as soon after the ladies had left as possible, and there would then have been plenty of time for Lloyd to hurry out and meet them before dark--especially plenty of time to meet them _coming back_, as they must have been, since they were carrying their ferns. The match was an article well chosen for its purpose, as being a not altogether unlikely thing to find on a dressing-table, and, if noticed, likely to lead to the wrong conclusions adopted by the official detective. "In Mrs. Armitage's case, the taking of an inferior brooch and the leaving of a more valuable ring pointed clearly either to the operator being a fool or unable to distinguish values, and certainly, from other indications, the thief seemed no fool. The door was locked, and the gasfitter, so to speak, on guard, and the window was only eight or ten inches open and propped with a brush. A human thief entering the window would have disturbed this arrangement, and would scarcely risk discovery by attempting to replace it, especially a thief in so great a hurry as to snatch the brooch up without unfastening the pin. The bird could pass through the opening as it was, and _would have_ to tear the pincushion to pull the brooch off--probably holding the cushion down with its claw the while.
