He started again, but less violently.

“Not bad!” he remarked. He cleared his throat. “You were off on the voice though and pretty far off, I’d say, on the perfume.”

Sunnat stared at him a moment, smile fading. “Hm!” she said coldly. She turned, swayed into Goth’s cabin. Goth came out a moment later, half frowning, half grinning.

“Thought I was her pretty good!” she stated. “Voice, too!”

“You were, really!” the captain admitted. “And just what, may I ask, was the idea?”

Goth hitched herself up on the communicator table and dangled her legs. “Got to practice,” she explained. “There’s a lot to it. Not easy to hold the whole thing together either!”

“Light waves, sound waves, and scents, eh? No, I imagine it wouldn’t be. That’s all you do?”

“Right now it’s all,” nodded Goth.

The captain reflected. “Another thing — if you saw that costume of hers, you were doing some underhanded snooping-around in Zergandol!”

“Looked like you might need help,” Goth said darkly.

“Well, I didn’t!”

“No.” She grinned. “Couldn’t know that, though. Want me to do Hulik? I got her down just right.”

“Another time.” The captain climbed out of the chair, adjusted the seat for her. “I’d better get some sleep. And you’d better forget about practicing and keep your eyes pinned to those screens! There’ve been a few flickers again.”

“Don’t worry!” She slipped down from the table, started over to him. Then they both froze.

There were short, screeching whistles, a flickering line of red on the console. An alarm -

“Strongbox!” hissed Goth.

They raced through the silent ship to the storage. The lounge was deserted, its lights dim. It had been ship-night for two hours.

The big storage door was shut, seemed locked, but swung open at the captain’s touch. The automatic lighting inside was on — somebody there! Cargo packed the compartment to the ship’s curved hull above. The captain brought out his gun as they went quickly down the one narrow aisle still open along the length of the storage, then came in sight of the vault at the far end to the left. The vault door — that massive, burglar-proof slab — stood half open.

Vezzarn lay face down in the door opening, legs within the vault as if he had stumbled and fallen in the act of emerging from it. He didn’t move as they scrambled past him. The interior of the vault hummed like a hive of disturbed giant insects. The strongbox stood against one wall, its top section tilted up. A number of unfamiliar tools lay on the floor about it. The humming poured up out of the box.

It was like wading knee-deep through thick, sucking mud to get to it! The captain’s head reeled in waves of dizziness. The humming deepened savagely. He heard Goth shout something behind him. Then he was bending over the opened box. Gray light glared out of it; cold fire stabbed — he seemed to be dropping forward, headlong into cold, gray distances, as his hands groped frantically about, found the tough, flexible plastic wrapping which had been pulled away from the crystal’s surface, wrenched, tugged it back into place.

In seconds they had it covered again, the plastic ends twisted tightly together; they stood gasping and staring at each other as the angry humming subsided. It was as if something that had been coming awake had gone back to sleep.

“Just in time here — maybe!” panted the captain. “Let’s hurry!”

They couldn’t get the strongbox closed all the way, left it as it was — top pulled down, a gap showing beneath it. They hauled Vezzarn clear of the vault door, shoved the door shut, spun its triple locks till they clicked back into position. The captain wrestled Vezzarn up to his shoulder. The old spacer might be dead or merely unconscious; in any case, he was a loose, floppy weight, difficult to keep a grasp on.

They got the storage door locked. Then Goth was off, darting back to the control section, the captain hurrying and stumbling after her with Vezzarn. There was still no sign of the two passengers — but that didn’t necessarily mean they were asleep in their staterooms.

He let Vezzarn slide to the control room floor and joined Goth at the instruments. The glittering dark of the Chaladoor swam about them but nothing of immediate importance was registering. Most particularly, nothing which suggested the far-off Worm World knew Olimy’s crystal had been uncovered again on a ship thundering along its solitary course through space. They exchanged glances.

“Might have been lucky!” the captain said. “If there’re no Nuris anywhere around here—” He drew in a long breath, looked back at Vezzarn. “Let’s try to get that character awake!”

Spluttering, swallowing, coughing, Vezzarn woke up a few minutes later. The captain pulled back the flask of strong ship brandy he’d been holding to the little spacer’s mouth, recapped it and set it on the floor. “Can you hear me, Vezzarn?” he asked loudly.

“Aaa-eeh,” sighed Vezzarn. He looked around and his face seemed to crumple. He blinked up at the captain, started to lift a hand to wipe his tear-filled eyes, and discovered handcuffs on his wrists. “Ah?” he muttered, frightened, then tried to meet the captain’s gaze again and failed. He cleared his throat. “Uh — what’s happened, skipper?”

“You’re going to tell us,” said the captain coldly. “Look over there, Vezzarn!”

Vezzarn turned his head in the indicated direction, saw the inner port of the control section lock yawning open, looked back apprehensively at the captain.

“Dani,” said the captain, nodding at Goth who sat sideways to them at the communicator table, an instrument case with dials on it before her, “is playing around with a little lie detector of ours over there! The detector is focused on you. Now—”

“I wouldn’t lie to you, skipper!” Vezzarn interrupted earnestly. “I just wouldn’t Anything you want to know I’ll—”

“We’ll see. If the detector says you’re lying—” the captain jerked his thumb at the lock. “You go out, Vezzarn! That way. I won’t listen to explanations. Out into the Chaladoor, as you are!” He moved back a step, put his hands on his hips, gave Vezzarn a glare for good measure. “Start talking!”

Vezzarn didn’t wait to ask what he should talk about. Hurriedly he began spilling everything he could think of about what had been told him of Captain Aron’s mystery drive, the voice who employed him, the change in assignment, his own plans, and events on the ship. “Now I’ve, uh, seen your drive, sir,” he concluded, voice quivering reminiscently, “I wouldn’t want the hellish thing! Not as a gift from you. I wouldn’t want to come anywhere near it again. I’m playing it honest. I’m your man, sir, until we’re through the Chaladoor and berthed safe on Emris. Believe me!”

The captain moved to the desk, turned down a switch. The lock sealed itself with a sharp snap. Vezzarn started, then exhaled in heavy relief.

“We seem to have a passenger on board who’s interested in the same thing,” the captain remarked. It wouldn’t hurt if Vezzarn believed the crystalloid was the mystery drive. That he wasn’t going near it again if he could help it was obvious. Apparently he’d fainted in sheer fright as he was trying to scramble out of the vault. “Which of them?”

“Both of them, I’d say,” Vezzarn told him, speaking a little more easily. “Couldn’t prove it — but they’ve both been moving around where they shouldn’t be.”

The captain studied him a moment. “I was assured,” he said then, “that short of a beam that could melt battle-steel, nobody would be able to force a way into that vault or to open that box until the time lock opened it—”

Vezzarn cleared his throat, produced a small, modest smile.

“Well, sir,” he said, “it’s possible you could find two men on Uldune who’re better safecrackers than I am. I’m not saying you would. It’s possible. But I’ll guarantee you couldn’t find three… I guess that explains it, sir!”
