“It is nothing,” he said faintly; “a temporary dizziness.”

“There is no time to be lost,” said Fisher, pressing forward. “The train leaves in twenty minutes. Get ready at once, and I will meanwhile attend to our friend.”

Fisher hurriedly led the Baron to his own bedroom. Savitch fell back upon the bed. The Baden symptoms repeated themselves. In two minutes the Russian was unconscious.

Fisher looked at his watch. He had three minutes to spare. He turned the key in the lock of the door and touched the knob of the electric annunciator.

Then, gaining the mastery of his nerves by one supreme effort for self-control, Fisher pulled the deceptive wig and the black skull-cap from the Baron’s head. “Heaven forgive me if I am making a fearful mistake!” he thought. “But I believe it to be best for ourselves and for the world.” Rapidly, but with a steady hand, he unscrewed the silver dome. The Mechanism lay exposed before his eyes. The Baron groaned. Ruthlessly Fisher tore out the wondrous machine. He had no time and no inclination to examine it. He caught up a newspaper and hastily enfolded it. He thrust the bundle into his open travelling-bag. Then he screwed the silver top firmly upon the Baron’s head, and replaced the skull-cap and the wig.

All this was done before the servant answered the bell. “The Baron Savitch is ill,” said Fisher to the attendant, when he came. “There is no cause for alarm. Send at once to the Hotel de l’Athénée for his valet, Auguste.” In twenty seconds Fisher was in a cab, whirling toward the Station St. Lazare.

When the steamship Pereire was well out at sea, with Ushant five hundred miles in her wake, and countless fathoms of water beneath her keel, Fisher took a newspaper parcel from his travelling-bag. His teeth were firm set and his lips rigid. He carried the heavy parcel to the side of the ship and dropped it into the Atlantic. It made a little eddy in the smooth water, and sank out of sight. Fisher fancied that he heard a wild, despairing cry, and put his hands to his ears to shut out the sound. A gull came circling over the steamer—the cry may have been the gull’s.

Fisher felt a light touch upon his arm. He turned quickly around. Miss Ward was standing at his side, close to the rail.

“Bless me, how white you are!” she said. “What in the world have you been doing?”
