He knew then that there could be but one answer, and he headed for the control room posthaste. Sure enough, the jump-board time-dial had been set for 8:00 p.m. of the same day. He looked at the s.p.a.ce-dial. That had been set to re-materialize the _Yore_ one half mile farther west.

He wiped his forehead. Good Lord, she might have sent the TSB all the way back to the Age of Reptiles! Even worse, she might have plunked it right down in the middle of WWIII!

She hadn't, though. In point of fact, she had done exactly what she had set out to do--taken the _Yore_ back to a point in time from which the Sangraal could be returned to the castle of Carbonek less than an hour after it had been stolen.

Suddenly he remembered how she had watched him from the doorway of the control room each time he had reset the time and s.p.a.ce-dials.

Technologically speaking, she was little more than a child, but jump-boards were as uncomplicated as modern technology could make them, and a person needed to be but little more than a child to operate them.

Grimly, Mallory returned to his bedroom-office and got into his armor; then, ignoring the throbbing of his reawakened wound, he mounted Easy Money and set out. He had no weapons, but it could not be helped. With a little luck, he would have need of none. He was about due for a little luck, if you asked him.

He gambled that Rowena would use the same route back to the chamber of the Sangraal that they had used in leaving it--actually, she had no other choice--and he encephalo-guided Easy Money at a fast trot in the direction of the river in the hope of overtaking her before she reached the entrance to the subterranean pa.s.sage. However, the hope did not materialize, and he saw no sign of her till he reached the entrance himself. Strictly speaking, he saw no sign of her then either, but he did discern several dislodged stones that could have been thrown up by the black rohorse's hoofs.

[Ill.u.s.tration]

Entering the pa.s.sage, he frowned. Until that moment, the incongruity of a sixth-century damosel encephalo-guiding a twenty-second century rohorse had not struck him. After a moment, though, he had to admit that the incongruity was not as glaring as it had at first seemed.

"Encephalopathing" was merely a glorified term for "thinking," and Rowena, shortly after mounting Perfidion's steed, must have made the discovery that she had only to think where she wanted to go in order for the rohorse to take her there.

He had not remembered to bring a light, nor did he need one. The infra-red rays of Easy Money's eye units were more than sufficient for the task on hand, and overtaking the girl would have been as easy as rolling off a log--if she hadn't been riding a rohorse, too.

Overtaking her wasn't of paramount importance anyway: he could confiscate the Sangraal after she returned it just as easily as he could before.

The odd part about the whole thing was that Mallory never once thought of the inevitable overlap till he saw the flicker of torchlight up ahead. An instant later he heard the sound of a woman's voice, and instinctively he encephalo-guided Easy Money into a nearby shallow cave.

[Ill.u.s.tration]

The flickering light grew gradually brighter, and presently hoofbeats became audible. The woman's voice was loud and clear now, and Mallory made out her words above the purling of the underground stream: "...

And then he set down the maiden, and was armed at all pieces save he lacked his spear. Then he dressed his shield, and drew out his sword, and Bors smote him so hard that it went through his shield and habergeon on the left shoulder. And through great strength he beat him down to the earth, and at the pulling of Bors' spear there he swooned. Then came Bors to the maid and said: How seemeth it to you of this knight ye be delivered at this time? Now sir, said she, I pray you lead me there as this knight had me. So shall I do gladly: and took the horse of the wounded knight, and set the gentlewoman upon him, and so brought her as she desired. Sir knight, said she, ye have better sped than ye weened, for an I had lost my maidenhead, five hundred men should have died for it. What knight was he that had you in the forest? By my faith, said she, he is my cousin. So wot I never with what engyn the fiend enchafed him, for yesterday he took me from my father privily: for I nor none of my father's men mistrusted him not, and if he had had my maidenhead he should have died for the sin, and his body shamed and dishonored for ever. Thus as...."

At this point, the truth behind the sense of _deja vu_ that Mallory had experienced the first time he had heard the tale hit him so hard between the eyes that he jerked back his head. When he did so, his helmet came into contact with the cave wall and sc.r.a.ped against the stone. The rohorse and its two riders were directly across the stream now. "_Shhh!_" Mallory I whispered.

Rowena I gasped. "It were best that I thanked ye now for thy great kindness, fair knight," she said, "for anon we be no longer on live."

"Nonsense!" Mallory I said. "If this fiend of yours is anywhere in the vicinity, he's probably more afraid of us than we are of him."

"Per ... peradventure he hath already had meat," Rowena I said hopefully. "The tale saith that an the fiend be filled he becomes aweary and besets not them the which do pa.s.s him by in peace."

"I'll keep my sword handy just in case he changes his mind," Mallory I said. "Meanwhile, get on with your autobiography--only for Pete's sake, cut it short, will you?"

"An it please, fair sir. Thus as the fair gentlewoman stood talking with Sir Bors there came twelve knights seeking after her, and anon...."

For a long while after the voices faded away, Mallory IV could not move. Hearing the story the second time and, more important, hearing it from the standpoint of an observer, he had been able to identify it for what it really was--an excerpt from _Le Morte d'Arthur_. The Joseph of Arimathea bit had been an excerpt, too, he realized now, probably lifted word for word from the text. It was odd indeed that a sixth-century damosel who presumably couldn't read could be on such familiar terms with a book that would not be published for another nine hundred and forty-three years.

But not so odd if she was a twenty-second century blonde in a sixth-century damosel's clothing.

Remembering Perfidion's secretary, Mallory felt sick. No, there was no noticeable resemblance between her and the damosel that hight Rowena; but the removal of a girdle and a quarter of a pound of makeup, not to mention the application of a "l.u.s.tre-rich" brown hair-dye and the insertion of a pair of plum-blue contact lenses, could very well have brought such a resemblance into being--and quite obviously had. The Past Police were noted for their impersonations, and most of them had eidetic memories.

_Come on, Easy Money_, Mallory encephalopathed. _You and I have got a little score to settle._

When he entered the chamber of the Sangraal, Rowena IV was arranging the red samite cover around the Grail. She jumped when she saw him.

"Marry! fair sir, ye did startle me. Methinketh ye be asleep in thy castle."

"Knock it off," Mallory said. "The masquerade's over."

She regarded him with round uncomprehending eyes. He got the impression that she had been crying. "The ... the masquerade, fair knight?"

"That's right ... the masquerade. You're no more the damosel Rowena than I'm the knight Sir Galahad."

She lowered her eyes to his breastplate. "I ... I wot well ye be not Sir Galahad, fair sir. It ... it happed that aforetime I did see Sir Galahad with my own eyes, and when ye did unlace thy unberere and I did see thy face, I knew ye could not be him of which ye spake."

Abruptly she raised her head and looked at him defiantly. "But I knew from thy eyes that ye be most n.o.ble, fair sir, and therefore an ye did pretend to be him the which ye were not, ye did so for n.o.ble cause, and it were not for me to question."

"I said knock it off," Mallory said, but with considerable less conviction. "I'm onto you--don't you see? You're a time-fink."

"A ... a time fink? I wot not what--"

"An agent of the Past Police. One of those do-gooders who run around history replacing stolen goods and turning in hard-working people like myself. You gave yourself away when you lifted that Sir Bors bit straight out of _Le Morte d'Arthur_ and--"

"But I did say ye sooth, fair sir. Sir Bors did verily succor my maidenhead. I wot not how there can be two of ye and two of me and four hackneys when afore there were but two, and I wot not how by touching the magic board in thy castle in a certain fashion that I could make the hour earlier and I wot not how the magic steed I did bestride brought me hither--I wot not none of these matters, fair sir.

I wot only that the magic of thy castle is marvelous indeed."

For a while, Mallory didn't say anything. He couldn't. In the plum-blue eyes fixed full upon his face, truth shone, and that same truth had invested her every word. The damosel Rowena, despite all evidence to the contrary and despite the glaring paradox the admission gave rise to, was not a phony, never had been a phony, and never would be a phony. She was, as a matter of fact--with the exception of Sir Galahad--the only completely honest person he had known in all his life.

"Tell me," he said, at length, "weren't you afraid to come back through that pa.s.sage alone? Weren't you afraid the fiend would get you?"

"La! fair sir--I had great fear. But it were not fitting that I bethought me of myself at such a time." She paused. Then, "What might be thy true name, sir knight?"

"Mallory," Mallory said. "Thomas Mallory."

"I have great joy of thy acquaintance, Sir Thomas."

Mallory only half heard her. He was looking at the samite-covered Sangraal. No more obstacles stood between him and his quest, and time was a-wasting. He started to take a step in the direction of the silver table.

His foot did not leave the floor.

He was acutely aware of Rowena's eyes. As a matter of fact, he could almost feel them upon his face. It wasn't that they were any different than they had been before: it was just that he was suddenly and painfully cognizant of the trust and the admiration that shone in them. Despite himself, he had the feeling that he was standing in bright and blinding sunlight.

Again, he started to take a step in the direction of the silver table.

Again, his foot did not leave the floor.

It wasn't so much the fact that she didn't believe he would take the Sangraal that bothered him: it was the fact that she couldn't conceive of him taking it. She could be convinced that black was white, perhaps, and that white was black, and that fiends hung out in empty caves and castles; but she could never be convinced that a "knight" of the qualities she imputed to Mallory could perform a dishonorable act.

And there it was, laid right on the line. For all the good the Grail was going to do Mallory, it might just as well have been at the bottom of the Mindanao Deep.

He sighed. His gamble hadn't paid off any more than Perfidion's had.

The real Sir Galahad was the one who had inherited the Grail after all--not the false one. The false one grinned ruefully. "Well," he told the damosel Rowena, "it's been nice knowing you." He swallowed; for some reason his throat felt tight. "I ... I imagine you'll be all right now."
