She added a guttural murmur in Apache. The Indians pushed forward as their leader snapped open the padlock. The heavy door swung open. All surged into the still-room except one of Lennon's guards, and he craned his neck to gape at the still. Into Lennon's ear breathed a faint whisper: "Keep back."

A moment later Carmena was darting in after the Apaches. She took her shielding hand away from the candle to point at a pile of jugs behind the still. With the gesture she called out in Apache. Cochise and all the others rushed to dig into the pile of jugs. Carmena glided to the still and bent down. She thrust the candle into the opening of the firebox.

For the first time Lennon grasped what the girl was about. And with that he realized in a flash all the cool courage and cleverness and self-sacrifice of the plan that she had schemed out against the brute force of Slade and the cruel cunning of Cochise. Elsie was safe hidden in the mummy room, Slade was dying or dead, and now she had lured Cochise and his murderous followers into the death trap!

He saw the flare of the lighted tinder in the firebox. The fuse must already be burning. Yet the girl remained stooped before the still. She would be blown to pieces no less certainly than the Apaches.

Lennon glanced desperately at his guard, who stood beside him in the doorway. The almost naked Apache was a mass of sinewy muscle, and his beady eyes were fixed upon the prisoner in alert watchfulness. Yet he was not quick enough to dodge Lennon's uppercut. He sprawled backward and struck his shock head upon the stone floor.

Carmena had straightened and faced about. At sight of Lennon bounding toward her she thrust out her hands in a repellant gesture.

He clutched her outflung hands and dragged her toward the door. From behind the still came an answering yell. Cochise and another Apache rushed around at the couple. Carmena lunged forward, to thrust Lennon at the doorway. Unbalanced by the shove, he stumbled over the Apache whom he had knocked senseless.

Carmena fell, rolled to one side, and struggled to her knees as Cochise leaped to the doorway after Lennon. Behind them roared a deafening detonation.

Though Lennon was out in the anteroom, he was hurled down by the force of the explosion. He staggered to his feet and faced about. In the thick of the smoke that spumed from the still-room Cochise bounded from the floor and came at him with upraised knife. Lennon barely saved himself by the quickest of side-stepping.

Cochise shot past, whirled, and closed in with the fury of a wildcat. Lennon's parry of the knife stab was sheer luck, but not the blow that he drove to the solar plexus. Superb as was the physical condition of the young Apache, that solid jolt sent him reeling back, gasping for breath.
