"Hang it up," he said.

The nobleman's breath was labored but he placed his receiver where it belonged; Mr. Heatherbloom did likewise. Both now stepped back. Upon the prince's brow stood drops of perspiration. The yacht had already slowed up and was turning. His excellency listened.

"May I ask how much longer you are desirous of my company here?"

"Oh, yes; you may ask."

The boat had begun to quiver again; she was going at full speed once more. Only now she headed directly for the land Mr. Heatherbloom wished to see. Five hours to an American port! Then? He glanced toward the door through which the girl had disappeared. Since that moment he had caught no sound from her. Had she heard, did she know anything of what was happening—that the yacht was now turned homeward? He dared not linger on the thought. The prince was watching him with eyes that seemed to dilate and contract. A moment's carelessness, the briefest cessation of watchfulness would be at once seized upon by his excellency, enabling him to shift the advantage. The young man met that expectant gleam.

"Sorry to seem officious, but if your excellency will sit down once more? Not here—over there!" Indicating a stationary arm-chair before a desk in a recess of the room.

The prince obeyed; he had no alternative. The fellow must, of course, be a madman, the prince reiterated in his own mind unless—

"I told your excellency I had no wish for a long sea voyage." A mocking voice now made itself heard.

The nobleman started, and looked closer; a mist seemed to fall from before his gaze. He recognized the fellow now—the man they had run down. The shock of that terrible experience, the strain of the disaster, had turned the fellow's brain. That would explain everything—this extraordinary occurrence. There was nothing to do but to humor him for the moment, though it was awkward—devilish!—or might soon be!—if this game should be continued much longer.

Mr. Heatherbloom glided silently toward the hangings near the alcove. What now?—the prince asked with his eyes. Mr. Heatherbloom unloosened from a brass holder a silk cord as thick as his thumb.
