"We're not in danger here," said Drengo, at his elbow. "No fire nor bomb can reach us here—that is the result of your mighty Atlantic Coast Barrier. Nothing more. It never was perfected in time, before the great Eastern Invasion and the second Atomic War. That was due to occur three years after the time-area where we visited. We were trying to stem it, to turn it aside. We don't know yet whether we succeeded or not."

He turned to the tall man standing at the door. "Markson, all the calculations are prepared. The Calc is evaluating the data against the Equation now, figuring all the variables. If our work did any good, we should know it soon." He sighed and pointed to the Palace. "But our fine Dictator is still alive, and the attack on Mars should be starting any minute—If we didn't succeed, nothing in all Time will stop him."

Roger lit a cigarette, his eyes questioning Drengo. "Dictator?"

Drengo sat down and stretched his legs. "The Dictator appeared four years ago, a nobody, a man from the masses of people on the planet. He rose into public favor like a sky-rocket, a remarkable man, an amazing man—a man who could talk to you, and control your thoughts in a single interview. There has never been a man with such personal magnetism and power, Roger, in all the history of Earth. A man who raised himself from nothing into absolute Dictatorship, and has handled the world according to his whim ever since.

"He is only a young man, Roger, just 32 years of age, but an irresistible man who can win anything from anybody. He writhed into the presidency first, and then deliberately set about rearranging the government to suit himself. And the people let him get away with it, followed him like sheep. And then he was Dictator, and he began turning the social and economic balance of the planet into a whirlwind. And then came Mars."

Martin stretched again, and lit a cigarette, his thin face grave in the darkened room. "The first landing was thirty years ago, and the possibilities for rich and peaceful commerce between Earth and Mars were clear from the first. Mars had what Earth lacked: the true civilization, the polished culture, the lasting socio-economic balance, the permanent peace. Mars could have taught us so much. She could have guided us out of the mire of war and hatred that we have been wallowing in for centuries. But the Dictator put an end to those possibilities." Drengo shrugged. "He was convinced that the Martians were weak, backward, decadent. He saw their uranium, their gold, their jewelry, their labor—and started on a vast impossible imperialism. If he had had his way, he would have stripped the planet in three years, but the Martians fought against us, turned from peace to suspicion, and finally to open revolt. And the Dictator could not see. He mobilized Earth for total war against Mars, draining our resources, decimating our population, building rockets, bombs, guns—" He stopped for a moment, breathing deeply. "But the Dictator didn't know what he was doing. He had never been on Mars. He has never seen Martians. He had no idea what they think, what they are capable of doing. He doesn't know what we know—that the Martians will win. He doesn't realize that the Martians can carry out a war for years without shaking their economy one iota, while he has drained our planet to such a degree that a war of more than two or three months will break us in half. He doesn't know that Mars can win, and that the Earth can't—"

Roger walked across the room, thoughtfully, his mind fitting pieces into place. "But where do I come in? David—Ann—I don't understand—"

Drengo looked Roger straight in the eye. "The Dictator's name," he said, "is Farrel Strang."

Roger stopped still. "Strang?" he echoed.

"Your son, Roger. Yours and Ann's."
