"But I didn't go," Quail said. "I won't have gone, no matter what proofs you provide me with." He took a deep, unsteady breath. "And I never was a secret agent with Interplan." It seemed impossible to him that Rekal, Incorporated's extra-factual memory implant would do its job -- despite what he had heard people say.

"Mr. Quail," McClane said patiently. "As you explained in your letter to us, you have no chance, no possibility in the slightest, of ever actually getting to Mars; you can't afford it, and what is much more important, you could never qualify as an undercover agent for Interplan or anybody else. This is the only way you can achieve your, ahem, life-long dream; am I not correct, sir? You can't be this; you can't actually do this." He chuckled. "But you can have been and have done. We see to that. And our fee is reasonable; no hidden charges." He smiled encouragingly.

"Is an extra-factual memory that convincing?" Quail asked.

"More than the real thing, sir. Had you really gone to Mars as an Interplan agent, you would by now have forgotten a great deal; our analysis of true-mem systems -- authentic recollections of major events in a person's life -- shows that a variety of details are very quickly lost to the person. Forever. Part of the package we offer you is such deep implantation of recall that nothing is forgotten. The packet which is fed to you while you're comatose is the creation of trained experts, men who have spent years on Mars; in every case we verify details down to the last iota. And you've picked a rather easy extra-factual system; had you picked Pluto or wanted to be Emperor of the Inner Planet Alliance we'd have much more difficulty... and the charges would be considerably greater."

Reaching into his coat for his wallet, Quail said, "Okay. It's been my life-long ambition and so I see I'll never really do it. So I guess I'll have to settle for this."

"Don't think of it that way," McClane said severely. "You're not accepting second-best. The actual memory, with all its vagueness, omissions and ellipses, not to say distortions -- that's second-best." He accepted the money and pressed a button on his desk. "All right, Mr. Quail," he said, as the door of his office opened and two burly men swiftly entered. "You're on your way to Mars as a secret agent." He rose, came over to shake Quail's nervous, moist hand. "Or rather, you have been on your way. This afternoon at four-thirty you will, um, arrive back here on Terra; a cab will leave you off at your conapt and as I say you will never remember seeing me or coming here; you won't, in fact, even remember having heard of our existence."

His mouth dry with nervousness, Quail followed the two technicians from the office; what happened next depended on them.

Will I actually believe I've been on Mars? he wondered. That I managed to fulfill my lifetime ambition? He had a strange, lingering intuition that something would go wrong. But just what -- he did not know.

He would have to wait and find out.

The intercom on McClane's desk, which connected him with the work area of the firm, buzzed and a voice said, "Mr. Quail is under sedation now, sir. Do you want to supervise this one, or shall we go ahead?"

"It's routine," McClane observed. "You may go ahead, Lowe; I don't think you'll run into any trouble." Programming an artificial memory of a trip to another planet -- with or without the added fillip of being a secret agent -- showed up on the firm's work-schedule with monotonous regularity. In one month, he calculated wryly, we must do twenty of these... ersatz interplanetary gravel has become our bread and butter.

"Whatever you say, Mr. McClane," Lowe's voice came, and thereupon the intercom shut off.

Going to the vault section in the chamber behind his office, McClane searched about for a Three packet -- trip to Mars -- and a Sixty-two packet: secret Interplan spy. Finding the two packets, he returned with them to his desk, seated himself comfortably, poured out the contents -- merchandise which would be planted in Quail's conapt while the lab technicians busied themselves installing false memory.

A one-poscred sneaky-pete side arm, McClane reflected; that's the largest item. Sets us back financially the most. Then a pellet-sized transmitter, which could be swallowed if the agent were caught. Code book that astonishingly resem­bled the real thing... the firm's models were highly accurate: based, whenever possible, on actual U.S. military issue. Odd bits which made no intrinsic sense but which would be woven into the warp and woof of Quail's imaginary trip, would coincide with his memory: half an ancient silver fifty cent piece, several quotations from John Donne's sermons written incorrectly, each on a separate piece of transparent tissue-thin paper, several match folders from bars on Mars, a stainless steel spoon engraved PROPERTY OF DOME-MARS NATIONAL KIBBUZIM, a wire tapping coil which --

The intercom buzzed. "Mr. McClane, I'm sorry to bother you but some­thing rather ominous has come up. Maybe it would be better if you were in here after all. Quail is already under sedation; he reacted well to the narkidrine; he's completely unconscious and receptive. But --"

"I'll be in." Sensing trouble, McClane left his office; a moment later he emerged in the work area.

On a hygienic bed lay Douglas Quail, breathing slowly and regularly, his eyes virtually shut; he seemed dimly -- but only dimly -- aware of the two technicians and now McClane himself.

"There's no space to insert false memory-patterns?" McClane felt irrita­tion. "Merely drop out two work weeks; he's employed as a clerk at the West Coast Emigration Bureau, which is a government agency, so he undoubtedly has or had two weeks' vacation within the last year. That ought to do it." Petty details annoyed him. And always would.

"Our problem," Lowe said sharply, "is something quite different." He bent over the bed, said to Quail, "Tell Mr. McClane what you told us." To McClane he said, "Listen closely."

The gray-green eyes of the man lying supine in the bed focussed on McClane's face. The eyes, he observed uneasily, had become hard; they had a polished, inorganic quality, like semi-precious tumbled stones. He was not sure that he liked what he saw; the brilliance was too cold. "What do you want now?" Quail said harshly. "You've broken my cover. Get out of here before I take you all apart." He studied McClane. "Especially you," he continued. "You're in charge of this counter-operation."

Lowe said, "How long were you on Mars?"

"One month," Quail said gratingly.

"And your purpose there?" Lowe demanded.

The meager lips twisted; Quail eyed him and did not speak. At last, drawling the words out so that they dripped with hostility, he said, "Agent for Interplan. As I already told you. Don't you record everything that's said? Play your vid-aud tape back for your boss and leave me alone." He shut his eyes, then; the hard brilliance ceased. McClane felt, instantly, a rushing splurge of relief.

Lowe said quietly, "This is a tough man, Mr. McClane."

"He won't be," McClane said, "after we arrange for him to lose his mem­ory-chain again. He'll be as meek as before." To Quail he said, "So this is why you wanted to go to Mars so terribly bad."

Without opening his eyes Quail said, "I never wanted to go to Mars. I was assigned it -- they handed it to me and there I was: stuck. Oh yeah, I admit I was curious about it; who wouldn't be?" Again he opened his eyes and sur­veyed the three of them, McClane in particular. "Quite a truth drug you've got here; it brought up things I had absolutely no memory of." He pondered. "I wonder about Kirsten," he said, half to himself. "Could she be in on it? An Interplan contact keeping an eye on me... to be certain I didn't regain my memory? No wonder she's been so derisive about my wanting to go there." Faintly, he smiled; the smile -- one of understanding -- disappeared almost at once.
