"You—Wisden!" gasped the person whose countenance was disguised by that hideous hood. "I—I——!" And he sank back into his chair.

"Now you know, you accursed fool!" exclaimed the mystery man. "And let that also sink into your silly noddle. Further, keep a still tongue. Be silent when you are up there, for people may listen and hear you. If they do, then you'll be discovered, and your death will be quick. Recollect that they are waiting for you—the affair isn't forgotten."

"No," sighed the weird figure. "No—I know it hasn't been forgotten. My crime!—my crime!"

"Yes. But don't refer to it. Just keep a level head, my dear Lionel, as you always do. I will still look after you if you remain silent and do what I order. I will supply you with everything. But be very careful that when I carry you up your food you don't speak. Somebody might overhear. These cursed walls have ears, although the old woman Felmore is deaf. Do you understand me?" he asked in a more imperative voice, rising, taking him by the shoulders, and shaking him. "Now tell me—you understand—eh?"

"Yes, yes!" the other gibbered in a strange tone. "You—Wisden—Willie Wisden! Oh, yes! I—I see! Dear old Willie, who was with me at Monte Carlo. Oh, yes! And that beautiful microscope?"

"You've got it upstairs. Don't you recollect it? Why, I gave it to you in the Terminus Hotel, in Marseilles, three years ago. Are you growing foolish? Surely not!"

"Yes. Oh, yes! I recollect now—the beautiful mike—oh, yes! Oh, what that instrument must have cost—oh, what a lot!—what a lot of money!"

"It did cost a good bit. And it's yours. So don't worry. I'll look after you, Lionel. But don't play the fool, or you'll go to the gallows over that unfortunate little affair—I warn you! Scotland Yard is looking everywhere for you, and they would have had you long ago if I hadn't taken you in hand and had pity upon you."

For a few moments the strange figure huddled in the chair remained silent.

"Yes—I know. And—and Lilla?" he asked.
