Steckel's voice suddenly drew his attention. The chief stood erect, gripping his gun tightly.

"Let's go, boys," he said quickly. "The place is clear now and we've got to get that killer!" He turned to Mortenson. "Which shack did he enter, Mortenson?"

"The big one at the left," replied the scientist.

"All right," said the chief. "Now let's spread out and surround it."

The violet sun was standing well west of its zenith. It seemed to cast grim, malignant shadows over the realm of mystery, death and terror. As they went quickly, but cautiously, toward the town, Mortenson felt something sinister in the terrible silence of the place. Surely they had not wiped out its citizens, leaving the phantom bandit there alone to reckon with fate. He decided that this was the case; that the town was merely an outpost, meagerly populated by roving bands of Fifth Dimension warriors. Perhaps, too, it was the headquarters of the vanishing bandit! He wondered if it was.

Then Steckel caught his eye and motioned to him. Instantly the chief broke into a run, closing in on the shack. It stood somewhat isolated by a narrow, crooked street. Mortenson followed him and they gained the shelter of the wall. Strangely, no sound came from the shack. It seemed as deserted as the town itself. The other men surrounded it completely, but Steckel and Mortenson were nearest to its single door.

Cautiously they peered in. It was a place of gloomy shadows, but on the far side Mortenson caught a glimpse of a shimmering curtain of blue. He knew what it was instantly. The phantom bandit was transferring himself back to their own world, leaving them without further resistance.

With a bound the scientist was in the shack. His pistol spat twice into the blue haze. He turned to Steckel.

"He's going back to our world, Chief!" he cried. "Call your men and we'll follow him!"

While Steckel bellowed to his men, Mortenson glanced around the shack. On the hard-packed floor lay piles of silver coin. Empty bags littered the floor in one corner. Stacks of currency of all denominations were piled neatly to one side. The phantom bandit had certainly made use of his ability to strike and vanish. Untold wealth lay on every hand in the unclean hut, but it would have to remain there for the present. He withdrew his fascinated eyes from it, as the men filed into the room.
