Time Patrol

by Poul Anderson

  "Yes." She lit another cigarette from the butt of the first. "I got worried right away. I asked the boss about it. He obliged me by querying himself a week ahead—today—and got the answer that Keith had not returned. The information clearinghouse said he never came to them. So we checked with Records in milieu headquarters. Their answer was . . . was . . . Keith never did come back and no trace of him was ever found."

  Everard nodded with great care. "Then, of course, the search was ordered which MHQ has a record of."

  Mutable time made for a lot of paradoxes, he reflected for the thousandth occasion.

  In the case of a missing man, you were not required to search for him just because a record somewhere said you had done so. But how else would you stand a chance of finding him? You might possibly go back and thereby change events so that you did find him after all—in which case the report you filed would "always" have recorded your success, and you alone would know the "former" truth.

  It could get very messed up. No wonder the Patrol was fussy, even about small changes which would not affect the main pattern.

  "Our office notified the boys in the Old Iranian milieu, who sent a party to investigate the spot," foretold Everard. "They only knew the approximate site at which Keith had intended to materialize, didn't they? I mean, since he couldn't know exactly where he'd be able to hide the scooter, he didn't file precise coordinates." Cynthia nodded. "But what I don't understand is, why didn't they find the machine afterward? Whatever happened to Keith, the scooter would still be somewhere around, in some cave or whatever. The Patrol has detectors. They should have been able to track down the scooter, at least, and then work backwards from it to locate Keith."

  She drew on her cigarette with a violence that caved in her cheeks. "They tried," she said. "But I'm told it's a wild, rugged country, hard to search. Nothing turned up. They couldn't find a trace. They might have, if they'd looked very, very hard—made a mile-by-mile, hour-by-hour search. But they didn't dare. You see, that particular milieu is critical. Mr. Gordon showed me the analysis. I couldn't follow all those symbols, but he said it was a very dangerous century to tamper with."

  Everard closed one large hand on the bowl of his pipe. Its warmth was somehow comforting. Critical eras gave him the willies.

  "I see," he said. "They couldn't search as thoroughly as they wanted, because it might disturb too many of the local yokels, which might make them act differently when the big crisis came. Uh-huh. But how about making inquiries in disguise, among the people?"

  "Several Patrol experts did. They tried that for weeks, Persian time. And the natives never even gave them a hint. Those tribes are so wild and suspicious . . . maybe they feared our agents were spies from the Median king, I understand they didn't like his rule. . . . No. The Patrol couldn't find a trace. And anyhow, there's no reason to think the pattern was affected. They believe Keith was murdered and his scooter vanished somehow. And what difference—" Cynthia sprang to her feet. Suddenly she yelled—"What difference does one more skeleton in one more gully make?"

  Everard rose too, she came into his arms, and he let her have it out. For himself, he had never thought it would be this bad. He had stopped remembering her, except maybe ten times a day, but now she came to him and the forgetting would have to be done all over again.

  "Can't they go back locally?" she pleaded. "Can't somebody hop back a week from now, just to tell him not to go, is that so much to ask? What kind of monsters made that law against it?"

  "Ordinary men did," said Everard. "If we once started doubling back to tinker with our personal pasts, we'd soon get so tangled up that none of us would exist."

  "But in a million years or more—there must be exceptions!"

  Everard didn't answer. He knew that there were. He knew also that Keith Denison's case wouldn't be one of them. The Patrol was not staffed by saints, but its people dared not corrupt their own law for their own ends. You took your losses like any other corps, and raised a glass to the memory of your dead, and you did not travel back to look upon them again while they had lived.

  Presently Cynthia left him, returned to her drink and tossed it down. The yellow locks swirled past her face as she did. "I'm sorry," she said. She got out a handkerchief and wiped her eyes. "I didn't mean to bawl."

  "It's okay."

  She stared at the floor. "You could try to help Keith. The regular agents have given up, but you could try."

  It was an appeal from which he had no recourse. "I could," he told her. "I might not succeed. The existing records show that, if I tried, I failed. And any alteration of space-time is frowned on, even a trivial one like this."

  "It isn't trivial to Keith," she said.

  "You know, Cyn," he murmured, "you're one of the few women that ever lived who'd have phrased it that way. Most would have said, It isn't trivial to me."

  Her eyes captured his, and for a moment she stood very quiet. Then, whispering:

  "I'm sorry. Manse. I didn't realize. . . . I thought, what with all the time that's gone past for you, you would have—"

  "What are you talking about?" he defended himself.

  "Can't the Patrol psychs do anything for you?" she asked. Her head drooped again. "I mean, if they can condition us so we just simply can't tell anyone unauthorized that time travel exists . . . I should think it would also be possible to, to condition a person out of—"

  "Skip it," said Everard roughly.

  He gnawed his pipestem a while. "Okay," he said at last. "I've an idea or two of my own that may not have been tried. If Keith can be rescued in any way, you'll get him back before tomorrow noon."

  "Could you time-hop me up to that moment, Manse?" She was beginning to tremble.

  "I could," he said, "but I won't. One way or another, you'll need to be rested tomorrow. I'll take you home now and see that you swallow a sleepy pill. And then I'll come back here and think about the situation." He twisted his mouth into a sort of grin. "Cut out that shimmy, huh? I told you I had to think."

  "Manse. . . ." Her hands closed about his.

  He knew a sudden hope for which he cursed himself.

  In the fall of the year 542 B.C., a solitary man came down out of the mountains and into the valley of the Kur. He rode a handsome chestnut gelding, bigger even than most cavalry horses, which might elsewhere have been an invitation to bandits; but the Great King had given so much law to his dominions that it was said a virgin with a sack of gold could walk unmolested across all Persia. It was one reason Manse Everard had chosen to hop to this date, sixteen years after Keith Denison's destination.

  Another motive was to arrive long after any excitement which the time traveler had conceivably produced in 558 had died away. Whatever the truth about Keith's fate, it might be more approachable from the rear; at least, straightforward methods had failed.

  Finally, according to the Achaemenid Milieu office, autumn 542 happened to be the first season of relative tranquility since the disappearance. The years 558-553 had been tense ones when the Persian king of Anshan, Kuru-sh (he whom the future knew as Koresh and Cyrus), was more and more at odds with his Median overlord Astyages. Then came three years when Cyrus revolted, civil war racked the empire, and the Persians finally overcame their northerly neighbors. But Cyrus was scarcely victorious before he must face counter-uprisings, as well as Turanian incursions; he spent four years putting down that trouble and extending his rule eastward. This alarmed his fellow monarchs; Babylon, Egypt, Lydia, and Sparta formed a coalition to destroy him, with King Croesus of Lydia leading an invasion in 546. The Lydians were broken and annexed, but they revolted and had to be broken all over again; the troublesome Greek colonies of Ionia, Caria, and Lycia must be settled with; and while his generals did all this in the west, Cyrus himself must war in the east, forcing back the savage horsemen who would otherwise burn his cities.

  Now there was a breathing spell. Cilicia would yield without a fight, seeing that Persia's other conquests were governed w
ith a humanity and a tolerance of local custom such as the world had not known before. Cyrus would leave the eastern marches to his nobles, and devote himself to consolidating what he had won. Not until 539 would the war with Babylon be taken up again and Mesopotamia acquired. And then Cyrus would have another time of peace, until the wild men grew too strong beyond the Aral Sea and the King rode forth against them to his death.

  Manse Everard entered Pasargadae as if into a springtime of hope.

  Not that any actual era lends itself to such flowery metaphors. He jogged through miles where peasants bent with sickles, loading creaky unpainted oxcarts, and dust smoked off the stubble fields into his eyes. Ragged children sucked their thumbs outside windowless mud huts and stared at him. A chicken squawked back and forth on the highway until the galloping royal messenger who had alarmed it was past and the chicken dead. A squad of lancers trotting by were costumed picturesquely enough, baggy pants and scaly armor, spiked or plumed helmets, gaily striped cloaks; but they were also dusty, sweaty, and swapping foul jokes. Behind adobe walls the aristocrats possessed large houses with very beautiful gardens, but an economy like this would not support many such estates. Pasargadae was ninety percent an Oriental town of twisted slimy streets between faceless hovels, greasy headcloths and dingy robes, screaming merchants in the bazaars, beggars displaying their sores, traders leading strings of battered camels and overloaded donkeys, dogs raiding offal heaps, tavern music like a cat in a washing machine, men who windmilled their arms and screamed curses—whatever started this yarn about the inscrutable East?

  "Alms, lord. Alms, for the love of Light! Alms, and Mithras will smile upon you! . . ."

  "Behold sir! By my father's beard I swear that never was there finer work from a more skilled hand than this bridle which I offer to you, most fortunate of men, for the ridiculous sum of . . ."

  "This way, master, this way, only four houses down to the finest sarai in all Persia—no, in all the world. Our pallets are stuffed with swan's down, my father serves wine fit for a Devi, my mother cooks a pilau whose fame has spread to the ends of the earth, and my sisters are three moons of delight available for a mere. . . ."

  Everard ignored the childish runners who clamored at his sides. One of them tugged his ankle, he swore and kicked, and the boy grinned without shame. The man hoped to avoid staying at an inn; the Persians were cleaner than most folk in this age, but there would still be insect life.

  He tried not to feel defenseless. Ordinarily a Patrolman could have an ace in the hole: say, a thirtieth-century stun pistol beneath his coat and a midget radio to call the hidden space-time antigravity scooter to him. But not when he might be frisked. Everard wore a Greek outfit: tunic and sandals and long wool cloak, sword at waist, helmet and shield hung at the horse's crupper, and that was it; only the steel was anachronistic. He could turn to no local branch office if he got into trouble, for this relatively poor and turbulent transition epoch attracted no Temporal commerce; the nearest Patrol unit was milieu HQ in Persepolis, a generation futureward.

  The streets widened as he pushed on, bazaars thinned out and houses grew larger. At last he emerged in a square enclosed by four mansions. He could see pruned trees above their outer walls. Guards, lean lightly armed youths, squatted beneath on their heels because standing at attention had not yet been invented. They rose, nocking wary arrows, as Everard approached. He might simply have crossed the plaza, but he veered and hailed a fellow who looked like a captain.

  "Greetings, sir, may the sun fall bright upon you." The Persian which he had learned in an hour under hypno flowed readily off his tongue. "I seek hospitality from some great man who may care to hear my poor tales of foreign travel."

  "May your days be many," said the guard. Everard remembered that he must not offer baksheesh: these Persians of Cyrus's own clans were a proud hardy folk, hunters, herdsmen, and warriors. All spoke with the dignified politeness common to their type throughout history. "I serve Croesus the Lydian, servant of the Great King. He will not refuse his roof to—"

  "Meander from Athens," supplied Everard. It was an alias which would explain his large bones, light complexion, and short hair. He had, though, been forced to stick a realistic Van Dyke effect on his chin. Herodotus was not the first Greek globetrotter, so an Athenian would not be inconveniently outré. At the same time, half a century before Marathon, Europeans were still uncommon enough here to excite interest.

  A slave was called, who got hold of the majordomo, who sent another slave, who invited the stranger through the gate. The garden beyond was as cool and green as hoped; there was no fear that anything would be stolen from his baggage in this household; the food and drink should be good; and Croesus himself would certainly interview the guest at length. We're playing in luck, lad, Everard assured himself, and accepted a hot bath, fragrant oils, fresh clothing, dates and wine brought to his austerely furnished room, a couch and a pleasant view. He only missed a cigar.

  Of attainable things, that is.

  To be sure, if Keith had unamendably died. . . .

  "Hell and purple frogs," muttered Everard. "Cut that out, will you?"

  After sunset it grew chilly. Lamps were lit with much ceremony, fire being sacred, and braziers were blown up. A slave prostrated himself to announce that dinner was served. Everard accompanied him down a long hall where vigorous murals showed the Sun and the Bull of Mithras, past a couple of spearmen, and into a small chamber brightly lit, sweet with incense and lavish with carpeting. Two couches were drawn up in the Hellenic manner at a table covered with un-Hellenic dishes of silver and gold; slave waiters hovered in the background and Chinese-sounding music twanged from an inner door.

  Croesus of Lydia nodded graciously. He had been handsome once, with regular features, but seemed to have aged a lot in the few years since his wealth and power were proverbial. Grizzled of beard and with long hair, he was dressed in a Grecian chlamys but wore rouge in the Persian manner. "Rejoice, Meander of Athens," he said in Greek, and lifted his face.

  Everard kissed his cheek as indicated. It was nice of Croesus thus to imply that Meander's rank was but little inferior to his own, even if Croesus had been eating garlic. "Rejoice, master. I thank you for your kindness."

  "This solitary meal was not to demean you," said the ex-king. "I only thought. . . ." He hesitated. "I have always considered myself near kin to the Greeks, and we could talk seriously—"

  "My lord honors me beyond my worth." They went through various rituals and finally got to the food. Everard spun out a prepared yarn about his travels; now and then Croesus would ask a disconcertingly sharp question, but a Patrolman soon learned how to evade that kind.

  "Indeed times are changing, you are fortunate in coming at the very dawn of a new age," said Croesus. "Never has the world known a more glorious King than," etc., etc., doubtless for the benefit of any retainers who doubled as royal spies. Though it happened to be true.

  "The very gods have favored our King," went on Croesus. "Had I known how they sheltered him—for truth, I mean, not for the mere fable which I believed it was—I should never have dared oppose myself to him. For it cannot be doubted, he is a Chosen One."

  Everard maintained his Greek character by watering the wine and wishing he had picked some less temperate nationality. "What is that tale, lord?" he asked. "I knew only that the Great King was the son of Cambyses, who held this province as a vassal of Median Astyages. Is there more?"

  Croesus leaned forward. In the uncertain light, his eyes held a curious bright look, a Dionysian blend of terror and enthusiasm which Everard's age had long forgotten. "Hear, and bring the account to your countrymen," he said. "Astyages wed his daughter Mandane to Cambyses, for he knew that the Persians were restless under his own heavy yoke and he wished to tie their leaders to his house. But Cambyses became ill and weak. If he died and his infant son Cyrus succeeded in Anshan, there would be a troublesome regency of Persian nobles not bound to Astyages. Dreams also warned the
Median king that Cyrus would be the death of his dominion.

  "Thereafter Astyages ordered his kinsman, the King's Eye Aurvagaush [Croesus rendered the name Harpagus, as he Hellenized all local names], to do away with the prince. Harpagus took the child despite Queen Mandane's protests; Cambyses lay too sick to help her, nor could Persia in any case revolt without preparation. But Harpagus could not bring himself to the deed. He exchanged the prince for the stillborn child of a herdsman in the mountains, whom he swore to secrecy. The dead baby was wrapped in royal clothes and left on a hillside; presently officials of the Median court were summoned to witness that it had been exposed, and buried it. Our lord Cyrus grew up as a herdsman.

  "Cambyses lived for twenty years more without begetting other sons, not strong enough in his own person to avenge the firstborn. But at last he was plainly dying, with no successor whom the Persians would feel obliged to obey. Again Astyages feared trouble. At this time Cyrus came forth, his identity being made known through various signs. Astyages, regretting what had gone before, welcomed him and confirmed him as Cambyses's heir.

  "Cyrus remained a vassal for five years, but found the tyranny of the Medes ever more odious. Harpagus in Ecbatana had also a dreadful thing to avenge: as punishment for his disobedience in the matter of Cyrus, Astyages made Harpagus eat his own son. So Harpagus conspired with certain Median nobles. They chose Cyrus as their leader, Persia revolted, and after three years of war Cyrus made himself the master of the two peoples. Since then, of course, he has added many others. When ever did the gods show their will more plainly?"

  Everard lay quiet on the couch for a little. He heard autumn leaves rustle dryly in the garden, under a cold wind.

  "This is true, and no fanciful gossip?" he asked.

  "I have confirmed it often enough since I joined the Persian court. The King himself has vouched for it to me, as well as Harpagus and others who were directly concerned."
