travel and the Lucky Larsons would have to live up to them, or else.

My mind was a long way away from the cabin of the space ship and maybe that's why I got what I did. I didn't see it coming. One minute I was walking through the aisle, thinking about Lucky Larson and the next second something slammed into the back of my head knocking me to my knees.

Through a haze of red and white lights I heard a voice bark, "Toss him into a chair and grab that good arm of his."

I wasn't out. Just damn sick. Something like a cold hand seemed to have closed over my stomach and for an awful moment I gagged and tried to retch. But the moment passed and I forced open my eyes and focused them on two tough-looking, hard-eyed gents who stood in front of me. Another unpleasant-looking little man knelt along side of me, twisting my good arm behind my back.

"Okay," I gritted, "what's the gag?"

The tallest of the three, evidently their leader, smiled at me. "It's no gag," he murmured calmly, "we happen to need the radium you're carrying. We're going to take it. Any objections?"

"You'll never get away with this," I snapped, "your names and descriptions are registered with the passenger office. You'll be tracked down in twenty-four hours."

I was bluffing, of course, and I knew from their contemptuous smiles that they knew it, too. They probably had given fictitious names, and the descriptive information which the bureau required consisted of a few generalities, such as height, weight and the like. I cursed myself for a stupid, careless fool. The three men had been the only passengers from Venus and they had kept to themselves the entire trip. Once or twice I had wondered at their reticence and quietness but I had not been suspicious enough to make a check-up.

One of the men laughed shortly. "Let us worry about that. We've covered every angle that could possibly come up. With the help of your friend up front, this ship will be flown to a certain deserted asteroid where a few friends of ours are to meet us with another ship. How you come out afterward will depend on how you co-operate now. Clear enough?"

It was clear enough all right. Lucky and I wouldn't last long after we served our purpose.

The tall man turned from me and nodded significantly to the man standing next to him and then pointed to the closed door to the pilot's chambers.

"Take care of the pilot," he murmured, "and tell him if he isn't obliging we'll take the cast off his friend's arm and—" he smiled at me, "massage it a bit."

I felt a cold sweat break out on my forehead.

The thug grinned wolfishly at me and then winked at his leader. "I'll tell him, boss." He dug his hand into his pocket and drew out a stubby atomic pistol. "If he won't listen to me maybe this'll persuade him."

Still grinning he turned and headed up the aisle, the gun clenched in his huge fist.

I glanced at the tall figure standing in front of me and saw that he was watching the retreating figure of his henchman with a saturnine smile on his face. I thought swiftly. If I could yell a warning to Lucky, he could bolt the door of the pilot's chamber and then set the ship down at the Trans-Space base. It was the only way to save Lucky and the radium. I wasn't very optimistic about my own chances. I knew they were zero.

I opened my mouth, took a deep breath and then, before I could scream the words that would warn Lucky, it happened. The ship shuddered for an instant and then zoomed upward, the smooth hum of the rocket motors crescendoing to a roaring song of power and speed.

The sudden jolting acceleration hurled me to the tail of the ship and I saw, like an image in a kaleidoscope, the tangled thrashing figures of the space bandits as they were tossed to the floor, a dazedly struggling mass of arms and legs.

The ship was lying over on its back in a few seconds, and before I could catch a breath it
