of the floor. Then it was withdrawn as suddenly as it appeared, and all was dark again save the single lurid spark which marked a chink between the stones.
Its disappearance, however, was but momentary. With a rending, tearing sound, one of the broad, white stones turned over upon its side, and left a square, gaping hole, through which streamed the light of a lantern. Over the edge there peeped a clean-cut, boyish face, which looked keenly about it, and then, with a hand on either side of the aperture, drew itself shoulder-high and waist-high, until one knee rested upon the edge. In another instant he stood at the side of the hole, and was hauling after him a companion, lithe and small like himself, with a pale face and a shock of very red hair.
"It's all clear," he whispered. "Have you the chisel and the bags. Great Scott! Jump, Archie, jump, and I'll swing for it!"
Sherlock Holmes had sprung out and seized the intruder by the collar. The other dived down the hole, and I heard the sound of rending cloth as Jones clutched at his skirts. The light flashed upon the barrel of a revolver, but Holmes's hunting crop came down on the man's wrist, and the pistol clinked upon the stone floor.
"It's no use, John Clay," said Holmes, blandly. "You have no chance at all."
"So I see," the other answered, with the utmost coolness. "I fancy that my pal is all right, though I see you have got his coat-tails."
"There are three men waiting for him at the door," said Holmes.
"Oh, indeed! You seem to have done the thing very completely. I must compliment you."
"And I you," Holmes answered. "Your red-headed idea was very new and effective."
"You'll see your pal again presently," said Jones. "He's quicker at climbing down holes than I am. Just hold out while I fix the derbies."
