checked it, and then he examined the many instruments on the panel in front of him. Finally, he flicked a switch on the control board.
At once, a small humming began, from some point overhead. It wavered and shrilled and mounted in intensity, and then fell to a steady monotone. The dome about him flickered with a queer, cold iridescence, and slowly vanished. The hidden room vanished, and he was looking into the shadowy interior of a deserted barn. The barn vanished; blue sky appeared above, streaked with wisps of high cirrus cloud. The autumn landscape flickered unreally. Buildings appeared and vanished, and other buildings came and went in a twinkling. All around him, half-seen shapes moved briefly and disappeared.
Once, the figure of a man appeared, inside the circle of the dome. He had an angry, brutal face, and he wore a black tunic piped with silver, and black breeches, and polished black boots, and there was an insignia, composed of a cross and thunderbolt, on his cap. He held an automatic pistol in his hand.
Instantly, the man at the desk snatched up his own weapon and thumbed off the safety, but before he could lift and aim it, the intruder stumbled and passed outside the force-field which surrounded the chair and instruments.
For a while, there were fires raging outside, and for a while, the man at the desk was surrounded by a great hall, with a high, vaulted ceiling, through which figures flitted and vanished. For a while, there were vistas of deep forests, always set in the same background of mountains and always under the same blue cirrus-laced sky. There was an interval of flickering blue-white light, of unbearable intensity. Then the man at the desk was surrounded by the interior of vast industrial works. The moving figures around him slowed, and became more distinct. For an instant, the man in the chair grinned as he found himself looking into a big washroom, where a tall blond girl was taking a shower bath, and a pert little redhead was vigorously drying herself with a towel. The dome grew visible, coruscating with many-colored lights and then the humming died and the dome became a cold and inert mesh of fine white metal. A green light above flashed on and off slowly.
He stabbed a button and flipped a switch, then got to his feet, picking up his rifle and musette and fumbling under his shirt for a small mesh bag, from which he took an inch-wide disk of blue plastic. Unlocking a container on the instrument panel, he removed a small roll of solidograph-film, which he stowed in his bag. Then he slid open the door and emerged into his own dimension of space-time.
Outside was a wide hallway, with a pale green floor, paler green walls, and a ceiling of greenish off-white. A big hole had been cut to accommodate the dome, and across the hallway a desk had been set up, and at it sat a clerk in a pale blue tunic, who was just taking the audio-plugs of a music-box out of his ears. A couple of policemen in green uniforms, with ultrasonic paralyzers dangling by thongs from their left wrists and bolstered sigma-ray needlers like the one on the desk inside the dome, were kidding with some girls in vivid orange and scarlet and green smocks. One of these, in bright green, was a duplicate of the one he had seen rubbing herself down with a towel.
"Here comes your boss-man," one of the girls told the cops, as he approached. They both turned and saluted casually. The man who had lately been using the name of Richard Lee responded to their greeting and went to the desk. The policemen grasped their paralyzers, drew their needlers, and hurried into the dome.
Taking the disk of blue plastic from his packet, he handed it to the clerk at the desk, who dropped it into a slot in the voder in front of him. Instantly, a mechanical voice responded:
"Verkan Vall, blue-seal noble, hereditary Mavrad of Nerros. Special Chief's Assistant, Paratime Police, special assignment. Subject to no orders below those of Tortha Karf, Chief of Paratime Police. To be given all courtesies and co-operation within the Paratime Transposition Code and the Police Powers Code. Further particulars?"
The clerk pressed the "no"-button. The blue sigil fell out the release-slot and was handed back to its bearer, who was drawing up his left sleeve.
"You'll want to be sure I'm your Verkan Vall, I suppose?" he said, extending his arm.
"Yes, quite, sir."
The clerk touched his arm with a small instrument which swabbed it with antiseptic, drew a minute blood-sample, and medicated the needle prick, all in one almost painless operation. He put the blood-drop on a slide and inserted it at one side of a comparison microscope,
