They both stood up and raised the prostrate form between them. Below them were the black waters of the lake.

“Over with him!” the younger said. “Quick!”

Once more his companion shrank away.

“Listen!” he muttered, hoarsely.

They both held their breaths. From somewhere along the road behind came a faint sound like the beating of an engine.

“It’s a car!” the elder man exclaimed. “Quick! Over with him!”

They lifted the body of the boy, whose lips were white and speechless now, and threw him into the water. With a great splash he disappeared. They watched for a moment. Only the ripples flowed away from the place where he had sunk. They jumped back to their seats.

“There’s something close behind,” the older man muttered. “Get on! Fast! Fast!”

The younger man hesitated.

“Perhaps,” he said slowly, “it would be better to wait and see who it is coming up behind. Our young friend there is safe. The current has him, and the tarn is bottomless.”
