"I know him," said Kauffman. "He's the night clerk at the Mansion House where I stop. Sometimes I see him when I come in late. He's not of special account; he's weak, ignorant, and—"

A sharp report interrupted him and alarmed them all.

Josie swung around quickly, for the sound—she knew it was a revolver shot—came from the rear. As Colton and Kauffman sprang to their feet and Mrs. Charleworth shrank back in a fright, the girl ran to the back door, opened it and started to make her way through the huge, dark building beyond the partition. The manager followed in her wake and as he passed through the door he turned a switch which flooded the big store-room with light.

In the center of the building were long, broad tables, used for packing. A few shells still remained grouped here and there upon the boards. On either side the walls were lined with tiers of boxes bound with steel bands and ready for shipment. No person was visible in this room, but at the farther end an outer door stood ajar and just outside it a motionless form was outlined.

Josie and Mr. Colton, approaching this outer door nearly at the same time, controlled their haste and came to an abrupt halt. The upright figure was that of Sergeant Joe Langley and the light from the room just reached a human form huddled upon the ground a few feet distant. Joe had dropped his flashlight and in his one hand held a revolver.

Josie drew a long, shuddering breath. The manager took a step forward, hesitated, and returned to his former position, his face deathly white.

"What is it? What's the matter?" called Kauffman, coming upon the scene panting for he was too short and fat to run easily.

Joe turned and looked at them as if waking from a trance. His stolid face took on a shamed expression.

"Couldn't help it, sir," he said to the manager. "I caught him in the act. It was the flashlight that saved us. When it struck him he looked up and the bullet hit him fair."

"Who is it, and what was he doing?" asked Mr. Colton hoarsely.
