"You mentioned his name a while ago." He glanced at Penny, and said, "Yuma."

Hoofs clattered close outside the house. Penny felt that now there surely would be a climax of events, and she was right. The masked man's manner changed abruptly. He listened for a moment as the hoofbeats stopped. A trace of a smile showed on his lips. His uncertainty gave way to grim and vigorous speech.

"You've wondered and asked," he snapped, "what I was going to do here. Now you'll find out."

Something about the transformation in the masked man made Penny want to shout. She felt that her trust in him had not been misplaced after all. The Lone Ranger shoved the table back, then kicked a hooked rug away from its place on the plank floor.

"This house has stood here a good many years," he said. "Before Bryant came here, it was used as a hiding place for army supplies when the Indians were bad. I've been told by a lot of old timers that there's a vault beneath this floor."

Penny knew about the vault. The trap door in the floor that led to it had been hidden by the carpet, but now it was exposed.

"That vault," continued the masked man, "was also used to hold prisoners when it wasn't convenient to move them. Well, it's going to be used to hold prisoners again."

Watching the men, still holding his gun on them, he threw back the trap door with a bang.

Lonergan's poker face was changed. Baffled fury showed in his black, snapping eyes. Lombard swore and Sawtell squinted grimly while his lips compressed to a thin line.
