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. "The crook has just returned to our world, men," Mortenson informed them crisply. "We're right on his trail! Press the first two panel buttons together; then press the third. We'll find ourselves within arm's reach of the killer. Be ready to shoot him on sight! Ready? Here we go!" Instantly the shack glowed with the peculiar pale blue luminosity cast off by the electronic apparatus. As one the men vanished, wondering where they would next appear. Within five seconds vague shapes began to dance before them. Then out of the jumbled maze of dancing, tottering forms they beheld familiar buildings. The dull rumble of traffic reached their ears above the drone of the apparatus. They emerged from the Fifth Dimension to find themselves standing directly in the middle of an intersection. The traffic was at a standstill while the corner signals changed. Instantly the crowds scattered. Women screamed and fainted. The traffic cop went into action, sensing something was about to happen, and held up the traffic. The bandit's pistol cracked. Mortenson felt a stab of pain in his right shoulder. He dropped his automatic and sagged to the street, a black nausea swept over him. He felt himself dropping into a yawning hole as a machine gun rattled almost in his face. Dimly he saw Barton standing over him, his machine gun spitting flame and death. For an instant the nausea left him, but the pain in his shoulder increased. Dazedly he looked around. A man was sagging limply near the curb. He was covered with blood and seemed dead on his feet. Then Mortenson recognized the phantom bandit as the man slumped from the curb and fell face-forward into the street. The pain in his shoulder intensified. He fainted. When he regained consciousness, Chief Steckel and Police Surgeon Wagner were standing beside his cot in the receiving hospital. After a moment he spoke: "Did you get his corpse, Wagner?" he inquired weakly, his brain still foggy from an anesthetic.
