"Well, I do know," affirmed McAllister.

"No-el! No-el! No-el! No-el!" rang out the bells, as McAllister left the club at twelve o'clock and started down the avenue.

"No-el! No-el!" hummed McAllister. "Pretty old air!" he thought. He had almost forgotten that it was Christmas morning. As he felt his way gingerly over the stone sidewalks, the bells were ringing all around him. First one chime, then another. "No-el! No-el! No-el! No-el!" They ceased, leaving the melody floating on the moist night air.

The snow began to fall irregularly in patchy flakes, then gradually turned to rain. First a soft, wet mist, that dimmed the electric lights and shrouded the hotel windows; then a fine sprinkle; at last the chill rain of a winter's night. McAllister turned up his coat-collar and looked about for a cab. It was too late. He hurried hastily down the avenue. Soon a welcome sight met his eye—a coupé, a night-hawk, crawling slowly down the block, on the lookout, no doubt, for belated Christmas revellers. Without superfluous introduction McAllister made a dive for the door, shouted his address, and jumped inside. The driver, but half-roused from his lethargy, muttered something unintelligible and pulled in his horse. At the same moment the dark figure of a man swiftly emerged from a side street, ran up to the cab, opened the door, threw in a heavy object upon McAllister's feet, and followed it with himself.

"Let her go!" he cried, slamming the door. The driver, without hesitation, lashed his horse and started at a furious gallop down the slippery avenue.

Then for the first time the stranger perceived McAllister. There was a muttered curse, a gleam of steel as they flashed by a street-lamp, and the clubman felt the cold muzzle of a revolver against his cheek.

"Speak, and I'll blow yer head off!"

The cab swayed and swerved in all directions, and the driver retained his seat with difficulty. McAllister, clinging to the sides of the rocking vehicle, expected every moment to be either shot or thrown out and killed.

"Don't move!" hissed his companion.
