"What's up?" Bill demanded.

Simon turned toward him with a scowl, and the match flickered and burned out in his fingers. "Keep your rifle ready. He may be hiding somewhere—still able to shoot."

They stole to the door of Linda's room and listened. Then they threw it wide.

One of their foes was in this room—an implacable foe whose eyes were glittering and strange in the matchlight. But it was neither Bruce nor Linda. It was old Elmira, cold and sinister as a rattler in its lair. Simon cursed her and hurried on.

At that instant both men began to move swiftly. Holding his rifle like a club, Simon swung through into, Bruce's room, lighted another match, then darted into the kitchen. In the dim matchlight the truth went home to him.

He turned, eyes glittering. "They've gone—on Dave's horse," he said. "Thank God they've only got one horse between 'em and can't go fast. You ride like hell up the trail toward the store—they might have gone that way. Keep close watch and shoot when you can make 'em out."

"You mean—" Bill's eyes widened.

"Mean! I mean do as I say. Shoot by sound, if you can't see them, and don't lose another second or I'll shoot you too. Aim for the man if a chance offers—but shoot, anyway. Don't stop hunting till you find them—they'll duck off in the brush sure. If they get through, everything is lost. I'll take the trail around the mountain."

They raced to their horses, untied them, and mounted swiftly. The darkness swallowed them at once.
