"Not a soul," said Jem, with great triumph.

"Then you may keep the ring," said the captain, and he stopped Jem's thanks by adding:

"Now for the gymnastics. Next to this room," and he touched the wall with his white forefinger, "there is an empty room which has been closed, screwed up, for years. I want to find a way of getting into that room on the quiet. I want to creep in there one night and out of it like a ghost——Why, what in the name of Jupiter is the matter with you?" he broke off to exclaim, for Jem's face had got as white as the supernatural phenomenon he, the captain, wished to imitate, and his eyes were fixed with horror and disquietude. "What's the matter with you, you idiot?"

"Captain, I'd climb the cliff, or walk a hundred miles, or—or—anything you'd ask me, but I can't go near that room! I've seen—there, never mind what I have seen! I won't go near it, and that's flat!"

The captain rose and walked to his bureau, from the drawer of which he took a neat little revolver.

Then, as if Jem had offered no objection he continued, in a smooth voice:

"I want you, Jem, to drop from this window onto the ivy beneath and to climb up to the window of the empty room. I will hold the one end of the rope, the other you shall tie round your waist. When you get to the window—which has no shutters—you will throw the light from the lantern all round the room and ascertain in what direction the door lies, what furniture the room contains, and its condition. In fact you shall give me a complete description of it. Do you go?"

"No," said Jem, with an oath. "I know what I've seen, and don't go interfering where a human being shouldn't. I don't go, captain."

The captain took out his watch and chain and dropped them on the floor.

"Very good," he said, raising the revolver with calm but suppressed passion, "this is the only thing I have asked you to do in return for all I have done for you. You cur, I saved you from the chain-gang. I have fed you, clothed you, made a man of you, and like an overfed dog you turn, do you? Move a step"—for Jem, stung by the truth in the taunt, had with a scowl advanced a step—"move an inch and I'll shoot you without further parley! I'll shoot you as it is," he continued, taking accurate aim.
