"There he goes—there! there!" shrilled out a chorus of excited voices, as the yellow-bearded, blue-bloused figure came into view. "After him! Catch him! Knife him!"

In an instant they were at the door, tumbling out into the darkness, pouring up the passage in hot pursuit. And it was at that moment the balance changed again. Those who were in the front rank of the pursuers were in time to see a lithe, thin figure—dressed as one of their own kind—spring up in the path of that other figure, jump on it, grip it, clap a huge square of sticky brown paper over the howling mouth of it, and bear it, struggling and kicking, to the ground.

In another second they, too, were upon it—swarming over it like rats, and digging and hacking at it with their dirks. And so they were still hacking at it—although it had long since ceased to move, or to make any sound—when Merode came up and called them to a halt.

"Drag it inside; let Margot have a thrust at it—it is her right. Pull off the dog's disguise, and bring me the plucky one that captured him. He shall have absinthe enough to swim in, the little king! Off with it all, Lanchere. First, the plaster—that's right. Now, the wig and beard, and after that—What's that you say? The beard is real? The hair is real? They will not come off? Name of the devil! what are you saying?"

"The truth, mon roi, the truth! Mother of disasters! It is not the cracksman—it is the real Clodoche we have killed!"

For one moment a sort of panic held them, swayed them, befogged the brains of them; then, of a sudden, Merode howled out, "Get back! Get back! The fellow's in there still!" and led a blind race down the passage to the bar, where they had seen Cleek last. It was still in darkness; but an eager hand gripping the lever, turned on the gas again, and matches everywhere were lifted to the jets.

And when the light flamed out and the room was again ablaze they knew that they might as well hope to call back yesterday as dream of finding Cleek again. For there on the floor, her limp hands turned palms upward, a chloroformed cloth folded over her mouth and nose, lay, in a deep stupor, the figure of Margot, her bodice torn wide open and the paper forever gone!

It was five minutes later when the Count von Hetzler, crouching back in the shadow of the square and waiting for the return of Clodoche, heard a dull, whirring sound that was unmistakably the purr of a motor throb through the stillness; and, leaning forward, saw an automobile whirl up out of the darkness, cut across the square, and dash off westward like a flash. Yet in the brief instant it took to go past the place where he waited there was time for him to catch the sharp click of a lowered window, see the clear outlines of a man's face looking out, and to hear a voice from within the vehicle speak.

"Herr Count," it said in clear, incisive tones. "A positively infallible recipe for the invasion of England: Wait until the Channel freezes and then skate over. Good night!"
