      Tortha Karf, Chief of Paratime Police, told himself to stop fretting. He was only three hundred years old, so by the barest life-expectancy of his race he was good for another two centuries. Two hundred more days wouldn’t matter. Then it would be Year-End Day, and, precisely at midnight, he would rise from this chair, and Verkan Vall would sit down in it, and after that he would be free to raise grapes and lemons and wage guerrilla war against the rabbits on the island of Sicily, which he owned outright on one uninhabited Fifth Level time-line. He wondered how long it would take Vall to become as tired of the Chief’s seat as he was now.

      Actually, Karf knew, Verkan Vall had never wanted to be Chief. Prestige and authority meant little to him, and freedom much. Vall liked to work outtime. But it was a job somebody had to do, and it was the job for which Vall had been trained, so he’d take it, and do it, Karf suspected, better than he’d done it himself. The job of policing a near-infinity of worlds, each of which was this same planet Earth, would be safe with Verkan Vall.

      Twelve thousand years ago, facing extinction on an exhausted planet, the First Level race had discovered the existence of a second, lateral, time-dimension and a means of physical transposition to and from a near-infinity of worlds of alternate probability parallel to their own. So the conveyers had gone out by stealth, bringing back wealth to Home Time Line—a little from this one, a little from that, never enough to be missed anywhen.

      It all had to be policed. Some Paratimers were less than scrupulous in dealing with outtime races—he’d have retired ten years ago except for the discovery of a huge paratemporal slave-trade, only recently smashed. More often, somebody’s bad luck or indiscretion would endanger the Paratime Secret, or some incident—nobody’s fault, something that just happened—would have to be explained away. But, at all costs, the Paratime Secret must be preserved. Not merely the actual technique of transposition—that went without saying—but the very existence of a race possessing it. If for no other reason (and there were many others), it would be utterly immoral to make any outtime race live with the knowledge that there were among them aliens indistinguishable from themselves, watching and exploiting. It was a big police-beat.

      Second Level: that had been civilized almost as long as the First, but there had been dark-age interludes. Except for paratemporal transposition, most of its sectors equaled First Level, and from many Home Time Line had learned much. The Third Level civilizations were more recent, but still of respectable antiquity and advancement. Fourth Level had started late and progressed slowly; some Fourth Level genius was first domesticating animals long after the steam engine was obsolescent all over the Third. And Fifth Level: on a few sectors, subhuman brutes, speechless and fireless, were cracking nuts and each other’s heads with stones, and on most of it nothing even vaguely humanoid had appeared.

      Fourth Level was the big one. The others had devolved from low-probability genetic accidents; it was the maximum probability. It was divided into many sectors and subsectors, on most of which human civilization had first appeared in the valleys of the Nile and Tigris-Euphrates, and on the Indus and Yangtze. Europo-American Sector: they might have to pull out of that entirely, but that would be for Chief Verkan to decide. Too many thermonuclear weapons and too many competing national sovereignties. That had happened all over Third Level at one time or another within Home Time Line experience. Alexandrian-Roman: off to a fine start with the pooling of Greek theory and Roman engineering talent, and then, a thousand years ago, two half-forgotten religions had been rummaged out of the dustbin and fanatics had begun massacring one another. They were still at it, with pikes and matchlocks, having lost the ability to make anything better. Europo-American could come to that if its rival political and economic sectarians kept on. Sino-Hindic: that wasn’t a civilization; it was a bad case of cultural paralysis. And so was Indo-Turanian—about where Europo-American had been ten centuries ago.

      And Aryan-Oriental: the Aryan migration of three thousand years ago, instead of moving west and south, as on most sectors, had rolled east into China. And Aryan-Transpacific, an offshoot: on one sector, some of them had built ships and sailed north and east along the Kuriles and the Aleutians and settled in North America, bringing with them horses and cattle and iron-working skills, exterminating the Amerinds, warring with one another, splitting into diverse peoples and cultures. There was a civilization, now decadent, on the Pacific coast, and nomads on the central plains herding bison and cross-breeding them with Asian cattle, and a civilization around the Great Lakes and one in the Mississippi Valley, and a new one, five or six centuries old, along
