space ship and the duplicating machine."

Muldoon spent a busy Thursday. A newsbrief in the Times financial section which told of a public utility wanting Island property gave him an idea for one thing. He spent all morning bringing the idea to a head, after he had verified the truth of the item. Then, after a late lunch, he went to the Treasury Department's headquarters and spent a couple of hours with the head of the local investigation department.

He was quite pleased with himself by nightfall, as he headed out to the Island. This time he parked the car at a considerable distance from the shack. There were lights on, this night. He walked boldly up and knocked at the door. It opened wide and the thick figure of one of the twins darkened the opening.

"Well, Mr. Muldoon. I did not think to see you till Friday."

"I thought I'd come and see you tonight," Muldoon said as he stepped into the room.

"I didn't hear the car."

"Oh. Parked it back a bit," Muldoon said. He turned toward the other twin as the inner door opened. "Hello."

"Hello."

"You know, Evin," Robert said, "I'm rather glad Muldoon stopped by tonight. We might as well conclude our business with him now."

"An excellent idea, Robert. Excellent."

"What do you mean?" Muldoon asked. "I no longer am acting for you?"

"Not for us, for yourself. I'm afraid your services, in any capacity, will no longer be needed."

Muldoon caught the undercurrent of menace in Robert's voice. It told him they were not only suspicious but ready to act on it. He started to edge toward the door, but Robert suddenly reached out and took his arm. There was power in the fat man's grip. Evin moved swiftly for his size, and took up a position before the door, which he kicked shut.

Muldoon twisted sharply and was free of the other's grip. He stepped back a couple of paces. "What the hell's this all about?"

"Come now, Muldoon," Robert said softly. "You didn't think your prying went unobserved, last night?"

"So I was nosey. But what's this rough stuff you're trying to pull?"

"Merely making sure your curiosity will end tonight."

Muldoon took a couple of more retreating paces. "You mean you're going to get rid of me? Well, maybe you will, and maybe you won't. But even if you do ..."

A smile broke through the grim lips of the twin threatening Muldoon. "You mean the duplicating machine? Just another piece of rusted scrap among the rest of the junk."

Muldoon paled. The evidence he was going to need, gone.

"And of course the money is genuine. We made sure of it. Ink, paper, everything. We made sure of it long ago. It will be a pity you won't be here to see how efficient we can really be. But the rest of the planet will know. As soon as Evin returns."

Muldoon's mind was working swiftly. "You got rid of the machine. But what about the junk shop it was in. I'll bet there are more important things there."

"Indeed there are. But no one will find it. It will be just another rusted piece of large junk to them."

It was then Muldoon made his move. He lashed out with a fist. The blow staggered Robert. And Muldoon was crashing his shoulder against the inner door. It burst inward, but before he could get through Robert grabbed him. The whole side of Muldoon's face went numb as Robert crashed his fist against his jaw. Muldoon knew he didn't stand a chance in a straight-up fight, not with these two. Robert's hands were reaching for him, now.

Muldoon grabbed one of the hands with both of his, twisted outward as he grasped two fingers in each hand. Robert's face went putty-grey as the bones snapped. Muldoon no longer cared about fair play. His knee came up where it could do most damage, and Robert sank grovelling to the floor.

Muldoon whirled. Too late. The world exploded in a thousand flashes of pain-filled lights. He went crashing backward into the wall. Evin hit him again before he stumbled blindly away from the terrible fist.
