in the doorway. Dyann brought her gun around. The silenced weapon hissed. One of the men tumbled with a hole drilled in his forehead. She was rather proud of herself, she'd never had much chance for target practice.
There wasn't much time for self-praise, though. The other man already had his rifle up. Dyann dropped behind the desk, and the stream of slugs ripped through the wood after her. She bunched her muscles and threw the desk. There was a crash of splintering wood as it knocked down the Jovian.
The secret police officer had his gun out and trained on her. Urushkidan snaked forth a tentacle and pulled him off his feet. Dyann stopped to slug Roshevsky-Feldkamp before she got her hands about the policeman's throat.
"Vere is Ray Ballantyne?" she growled.
"Come on, come on, we habe to get out of here!" wailed the Martian.
"Vich is the vay out?"
"I'll show you—come along, quick—tis way."
Dyann frogmarched the Jovian cop toward a rear door. Booted feet were thudding up the stairs toward the office. Urushkidan held a pistol in each hand, gingerly as if he feared they would blow up. He led the way into a hall and down a long, echoing ramp.
"Hurry, hurry," he gasped. "Shalmuannusar, we habe te whole Jobian Confederacy after us!"
A voice bellowed atop the ramp and a slug whanged after them. Dyann whirled and fired back, using the helplessly pinioned captive as a shield. They retreated slowly, rounding a corner and going on down a long slope to a heavy steel door.
Urushkidan opened it, slamming it frantically as they went through. They were in a hangar where several small spaceships rested on their rail-mouthed cradles. Mechanics stared at the trio.
"Quick!" snapped the Martian. "Te laboratory ships!"
The prisoner opened his mouth. Dyann laid a friendly hand on the back of his neck and squeezed a little.
"Yes, yes, the laboratory ship—practice maneuvers—hurry!" the man said.
"Aye, sir! At once!" A life time's training in blind obedience spoke there, behind the puzzled faces.
A teardrop-shaped rocket was trundled forth. Dyann looked nervously back at the door. Pursuit was most likely playing it safe, posting men outside while others went around to block all remaining exits. Once that was done they'd close in.
"I'll warm up the engine for you, sir," said one of the mechanics.
"Ve'll take it now," said Dyann.
"But you can't! You'll carbon the tubes—be likely to crash—"
"I said now." Dyann propelled her captive ahead of her through the airlock and Urushkidan crawled after. The valves clanged shut after them.
"I hope you can fly vun of these thins," said Dyann, lashing the secret policeman to a recoil chair.
"I hope so too," said Urushkidan.
Dyann stood over her prisoner. "Vere is Ray Ballantyne?" she asked. "The Earthman who vas arrested off the liner a few days ago."
"I don't know," he gasped.
Dyann drew her knife, smiling nastily.
"Camp Muellenhoff, you savage! Outside the city, to the north. You'll never make it. You'll kill us all."
The cradle rumbled forward to the hangar airlock. Urushkidan took the pilot chair and strapped himself in and relit his pipe with nervous boneless fingers. Dyann whistled tunelessly between her teeth. It was dark in the airlock chamber as the pumps evacuated it.
"Why bother wit tis Ballantyne?" asked the Martian. "What claim has he on us? It will need all our luck and my genius for us to escape with our own lives."
"We need his luck too, maybe," said Dyann shortly.

The outer valve swung open and they trundled over the rails to the surface of Ganymede. Behind them, the dome covering the city rose against a background of saw-toothed mountains and dark, faintly star-lit sky. A dwarfed sun lit the spaceport field with pale cold luminance. There were not many vessels in sight, no liner or freighter was in and the military ports were elsewhere. One lean black patrol ship stood not far off.
"They vill be out after us soon," said Dyann. "Vat can you do about that boat there, huh?"
"We will see," said Urushkidan. He touched studs, levers, and buttons. The engines thuttered and the little vessel shook.
"Let's go!"
The rocket stood on her tail and climbed for the sky. Urushkidan brought her around, the gyros screaming at his clumsy management, and lowered her on her jets directly above the patrol ship. An atom-driven ion-blast is not good for a patrol ship.
"Now," said Dyann as they took off again, "you, my policeman friend, vill call this Camp Muellenhoff and tell them to release Ballantyne to us. If you do that, ve vill set you down somevere. If not—vell—" She tested the edge of her knife on his ear. "You may still be a police, but you vill not be very alive."
"You can't escape," said the Jovian with a certain hollow lack of conviction. "You'd better throw yourself on the Leader's mercy."
Dyann knocked a few teeth loose.
"You savage!" he gasped. "You cruel, murdering—"
"I tought you Jobians were always talking about te glories of war and te rutless superman," snickered Urushkidan. "Also destiny and tings. Better call te camp as she says."
A few minutes later the ship lowered into the walled enclosure of Camp Muellenhoff. It was a dreary place, metal barracks lying harsh under the guns of the watchtowers, spacesuited prisoners clumping to work through the thin chill air of Ganymede. A detail hurried up and shoved an unarmed, suited form into the airlock.
Their leader's voice rattled over his helmet radio of the ship's telereceiver, "Major, sir, are you sure they want this man in the city now? We just got an alert to look out for a couple of escaped desperadoes."
Dyann slammed the outer valve in his face by the remote-control lever and the little ship stood on her tail again and flamed skyward.
A somewhat battered Ray Ballantyne crawled out of his suit and blinked at them. It had been a rough two or three days, though they hadn't gone very far with him. The truth drugs must have satisfied them that he was not an intentional spy, and thereafter they had simply held him until orders for his execution should come. He swayed into Dyann's arms.
"Oh, my poor Ray," she murmured. "My poor, poor little Earthlin."
"Hey, wait a minute," he began weakly.
"Just lie still, I will take care of you."
"Yeah, that's what I'm afraid of. Lemme go!"
They sat down again on a remote mountaintop, gave the policeman a spacesuit, and kicked him out of the ship. He was still wailing about barbarous and inhuman treatment. He said something too about wild beasts.
"And now," said Dyann, "let us get back to Earth before the Yovians find us."
"This crate'll never make Earth," said Ray. "I've flown 'em—let me at those controls, Urushkidan."
They heard it as well, the ominous sizzling and knocking from the engine-room shields, and felt the ship tremble with it.
"Is tat te carboning te man was talking about?" asked the Martian innocently.
"I'm—afraid—so." Ray shook his head. "We'll have to land somewhere before the rockets quit altogether. Then it'll take a week for the radioactivity to get low enough so we can go back there and clean them out."
"And all the Yovian army, navy, police, and fire department out chasin us by now," said Dyann. Her clear brow wrinkled. "I fear that Ormun is offended because I left her amon the heathen back there. I am afraid our luck is runnin' low."
"And," said Ray bleakly, "how!"
