They spun around to see Stutsman standing in the doorway of the control room. His face was twisted into a wolfish grin and in his right hand he held a heat gun.

Chambers' voice was sharp, like the note of a clanging bell. "What's this?"

Stutsman's face twisted into an even more exaggerated grin. "This," he said, "is mutiny. I'm taking over!" He laughed at them.

"No use calling the crew. They're with me."

"Damn you!" shouted Chambers, taking a step forward. He halted as Stutsman jerked the pistol up.

"Forget it, Chambers. You're just second man from now on. Maybe not even second man. You tried out this dictator business and you bungled it. You went soft. You're taking orders from me from now on. No questions, no back talk. You do as I say and maybe you won't get hurt."

"You're mad, Stutsman!" cried Chambers. "You can't get away with this."

Stutsman barked out a brittle laugh. "Who is going to stop me?"

"The people," Chambers shouted at him. "The people will. They won't allow this. When you get back to the Solar System ..."

Stutsman growled, stepping toward Chambers, pistol leveled. "The people won't have anything to say about this. I'll rule the Solar System the way I want to. There won't be anyone else who'll have a thing to say about it. So you dreamed of empire, did you? You dreamed of a solar dictatorship. Well, watch me! I'll build a real empire. But I'll be the head of it ... not you."

Craven sat down in his chair, crossed his knees. "Just what do you plan to do, Dictator Stutsman?"

Stutsman fairly foamed at the mouth over the insolence of Craven's voice. "I'll smash Manning first. I'll wipe him out. This ship will do it. You said yourself it would. You have ten times the power he has. And then ..."

Craven raised a hand and waved him into silence. "So you plan to reach the Solar System, do you? You plan to meet Manning, and destroy his ship. Nice plan."

"What's wrong with it?" challenged Stutsman.

"Nothing," said Craven calmly. "Absolutely nothing at all ... except that we may never reach the Solar System!"

Stutsman seemed to sag. The wolfish snarl on his lips drooped. His eyes stared. Then with an effort he braced himself.

"What do you mean? Why can't we?" He gestured toward the vision plate, toward the tiny yellow star between the two brighter stars.

"That," said Craven, "isn't our Sun. It has planets, but it isn't our Sun."

Chambers stepped quickly to Craven, reached out a hand and hoisted him from the chair, shook him.

"You must be joking! That has to be the Sun!"

Craven shrugged free of Chambers' clutch, spoke in an even voice. "I never joke. We made a mistake, that's all. I hadn't meant to tell you yet. I had intended to get in close to the star and take on a full load of power and then try to locate our Sun. But I'm afraid it's a hopeless task."

"A hopeless task?" shrieked Stutsman. "You are trying to trick me. This is put up between the two of you. That's the Sun over there. I know it is!"

"It isn't," said Craven. "Manning tricked us. He started off in the wrong direction. He made us think he was going straight back to the Solar System, but he didn't. He circled and went in some other direction."

The scientist eyed Stutsman calmly. Stutsman's knuckles were white with the grip he had upon the gun.

"We're lost," Craven told him, looking squarely at him. "We may never find the Solar System!"

CHAPTER TWENTY

The revolution was over. Interplanetary officials and army heads had fled to the sanctuary of Earth. Interplanetary was ended ... ended forever, for on every world, including Earth, material energy engines were humming. The people had power to burn, to throw away, power so cheap that it was practically worthless as a commodity, but invaluable as a way to a new life, a greater life, a fuller life ... a broader destiny for the human race.

Interplanetary stocks were worthless. The mighty power plants on Venus and Mercury were idle. The only remaining tangible asset were the fleets of spaceships used less than a month before to ship the accumulators to the outer worlds, to bring them Sunward for recharging.

Patents protecting the rights to the material energy engines had been obtained from every government throughout the Solar System. New governments were being formed on the wreckage of the old. John Moore Mallory already had been inaugurated as president of the Jovian confederacy. The elections on Mars and Venus would be held within a week.

Mercury, its usefulness gone with the smashing of the accumulator trade, had been abandoned. No human foot now trod its surface. Its mighty domes were empty. It went its way, as it had gone for billions of years, a little burned out, worthless planet, ignored and shunned. For a brief moment it had known the conquering tread of mankind, had played its part in the commerce of the worlds, but now it had reverted to its former state ... a lonely wanderer of the regions near the Sun, a pariah among the other planets.
