The cat leaped off the sill an instant ahead of his arrival, dodged the downward sweep of the cane and ran toward the open field in the rear of the house. He cursed, regained his balance and whirled after it. A low mist had risen over the meadow; it was like a curtain of grey-white shadow in the moonlight. Momentarily he lost sight of the beast; then he glimpsed it again, bellying its way slowly through the wet grass. It crawled with a queer dragging of its hindquarters, as if it had been injured, and frequently it looked back. He took a firmer grip on the cane and rushed forward with a feeling of exultation. His first swing of the cane must have struck it after all! He would catch it now! He would be upon it in an instant! The sneaking, murderous black devil--he'd pound it to a pulp! Ah, now he had it! He swung the heavy cane with all his strength. The cat leaped nimbly aside, ran a few yards, then stopped and turned its head, fixing its eerie yellow eyes on him. The sweep of his arm had caused him to lose his balance and now as he lunged in pursuit again he lost his footing entirely; his feet shot sideways on the slippery grass and he crashed to the ground. He was up in an instant, cursing, frantic with rage, and sprang toward the motionless cat. The animal waited until he was almost upon it, then quickly dodged aside and ran in another direction. He was out of breath now, but it never occurred to him to abandon the chase. He rushed after the hated black beast which ran ever ahead of him in the swirling mist, now scarcely crawling, now darting out of reach with the suddenness of a whiplash, now pausing and turning its flat head to make sure he was following behind. He leaped forward like a madman, striking out savagely with the cane, sliding to his hands and knees, a wild frenzied figure in the moonlight. He was possessed by the one idea; he had lost all sense of proportion, of direction; he did not even know into which part of the meadow he had ventured. Suddenly the cat made a long leap. It landed heavily and appeared to go limp. It looked back but did not move as he lunged forward. Without warning the ground vanished beneath his feet and he plunged downward like a stone. Even as he fell he understood the trap to which he had been led. With demoniac cunning, the cat had caused him to run directly over the shaft of a deep abandoned well which was located in the rear unused portion of the meadow. He screamed once before the black water closed over his head, sending him straight down a pool of freezing darkness. He kicked and clawed and at last came to the surface, but already the icy water was working its paralysis in him. He stared up and screamed again, but the steep walls of the well smothered his cry; it was little more than a weak moan above the surface of the ground.
