Charles rose excitedly, and put his back against the door. "Secure that man," he said to me sharply, pointing with his finger.

"What man?" I asked, amazed. "Colonel Clay? The young man who's downstairs now with Césarine?"

"No," Charles answered, with decision; "Dudley!"

I laid my hand on the footman's shoulder, not understanding what Charles meant. Dudley, terrified, drew back, and would have rushed from the room; but Charles, with his back against the door, prevented him.

"I—I've done nothing to be arrested, Sir Charles," Dudley cried, in abject terror, looking appealingly at Amelia. "It—it wasn't me as cheated you." And he certainly didn't look it.

"I daresay not," Charles answered. "But you don't leave this room till Colonel Clay is in custody. No, Amelia, no; it's no use your speaking to me. What he says is true. I see it all now. This villain and Césarine have long been accomplices! The man's downstairs with her now. If we let Dudley quit the room he'll go down and tell them; and before we know where we are, that slippery eel will have wriggled through our fingers, as he always wriggles. He is Paul Finglemore; he is Césarine's young man; and unless we arrest him now, without one minute's delay, he'll be off to Madrid or St. Petersburg by this evening!"

"You are right," I answered. "It is now or never!"

"Dudley," Charles said, in his most authoritative voice, "stop here till we tell you you may leave the room. Amelia and Dolly, don't let that man stir from where he's standing. If he does, restrain him. Seymour and Dr. Beddersley, come down with me to the servants' hall. I suppose that's where I shall find this person, Dudley?"

"N—no, sir," Dudley stammered out, half beside himself with fright. "He's in the housekeeper's room, sir!"

We went down to the lower regions in a solid phalanx of three. On the way we met Simpson, Sir Charles's valet, and also the butler, whom we pressed into the service. At the door of the housekeeper's room we paused, strategically. Voices came to us from within; one was Césarine's, the other had a ring that reminded me at once of Medhurst and the Seer, of Elihu Quackenboss and Algernon Coleyard. They were talking together in French; and now and then we caught the sound of stifled laughter.
