"Who are you?" he asked roughly.

"My name is Adrian Fisher," was the reply. This astonished the detective, but it pleased him too, for it seemed to confirm the suspicion that this man was an accomplice. He decided quickly to say no more to him at that time, and hastened towards Miss Remsen to observe her behavior. If she knew anything in advance she certainly was acting admirably, for she had grown excited, and was talking vehemently to those about her, declaring against the disgraceful management, so she termed it, which had enabled a thief to enter the rooms.

Whilst Mr. Barnes was thinking what to do, he saw Mr. Van Rawlston approaching him, accompanied by Mr. Thauret, who was now in evening dress.

"Mr. Barnes, how was this thing done? Why did you not prevent it?"

"I tried to do so, but could not. You must understand, Mr. Van Rawlston, that I am not omniscient. I suspected that this robbery would occur, but I could not know how it would be accomplished. Nevertheless I saw the act."

"Then why did you not seize the thief?"

"I attempted to do so, and was thrown down from behind by his accomplice."

"Can you identify the person by his dress?"

"That is, unfortunately, impossible. All that I know is that he was one of the Forty Thieves, and evidently played his part well."

"This is Mr. Barnes?" said Mr. Thauret, inquiringly, continuing at once: "Yes, of course it is. We have met twice, I think. You say your thief was dressed as one of the Forty Thieves. That interests me, for I wore one of those dresses. Why not ask all who did to allow themselves to be searched?"
