They skirted the bulkhead of the main air tank. They headed along the broader corridor which went past the indented inner door of the air lock. They had reached that indentation when Baird saw that the inner air-lock door was closing. He saw a human pressure suit past its edge. He saw the corner of some object that had been put down on the air-lock floor.

Baird shouted, and rushed toward the lock. He seized the inner handle and tried to force open the door again, so that no one inside it could emerge into the emptiness without. He failed. He wrenched frantically at the control of the outer door. It suddenly swung freely. The outer door had been put on manual. It could be and was being opened from inside.

"Tell the skipper," raged Baird. "Taine's taking something out!" He tore open a pressure-suit cupboard in the wall beside the lock door. "He'll make the Plumies think it's a return-gift for the generator!" He eeled into the pressure suit and zipped it up to his neck. "The man's crazy! He thinks we can take their ship and stay alive for a while! Dammit, our air would ruin half their equipment! Tell the skipper to send help!"

He wrenched at the door again, jamming down his helmet with one hand. And this time the control worked. Taine, most probably, had forgotten that the inner control was disengaged only when the manual was actively in use. Diane raced away, panting. Baird swore bitterly at the slowness of the outer door's closing. He was tearing at the inner door long before it could be opened. He flung himself in and dragged it shut, and struck the emergency air-release which bled the air lock into space for speed of operation. He thrust out the outer door and plunged through.

His momentum carried him almost too far. He fell, and only the magnetic soles of his shoes enabled him to check himself. He was in that singular valley between the two ships, where their hulls were impregnably welded fast. Round-hulled Plumie ship, and ganoid-shaped Niccola, they stuck immovably together as if they had been that way since time began. Where the sky appeared above Baird's head, the stars moved in stately procession across the valley roof.

He heard a metallic rapping through the fabric of his space armor. Then sunlight glittered, and the valley filled with a fierce glare, and a man in a human spacesuit stood on the Niccola's plating, opposite the Plumie air lock. He held a bulky object under his arm. With his other gauntlet he rapped again.

"You fool!" shouted Baird. "Stop that! We couldn't use their ship, anyhow!"

His space phone had turned on with the air supply. Taine's voice snarled:

"We'll try! You keep back! They are not human!"

But Baird ran toward him. The sensation of running upon magnetic-soled shoes was unearthly: it was like trying to run on fly-paper or bird-lime. But in addition there was no gravity here, and no sense of balance, and there was the feeling of perpetual fall.

There could be no science nor any skill in an encounter under such conditions. Baird partly ran and partly staggered and partly skated to where Taine faced him, snarling. He threw himself at the other man—and then the sun vanished behind the bronze ship's hull, and only stars moved visibly in all the universe.

But the sound of his impact was loud in Baird's ears inside the suit. There was a slightly different sound when his armor struck Taine's, and when it struck the heavier metal of the two ships. He fought. But the suits were intended to be defense against greater stresses than human blows could offer. In the darkness, it was like two blindfolded men fighting each other while encased in pillows.

Then the sun returned, floating sedately above the valley, and Baird could see his enemy. He saw, too, that the Plumie air lock was now open and that a small, erect, and somehow jaunty figure in golden space armor stood in the opening and watched gravely as the two men fought.
