"I did it as a surprise for Gusterson," she explained to Fay. "He says he likes me this way. The green glop's supposed to be smudgeproof."

Gusterson did not comment. His face had a rapt expression. "I'll tell you why your tickler's so popular, Fay," he said softly. "It's not because it backstops the memory or because it boosts the ego with subliminals. It's because it takes the hook out of a guy, it takes over the job of withstanding the pressure of living. See, Fay, here are all these little guys in this subterranean rat race with atomic-death squares and chromium-plated reward squares and enough money if you pa.s.s Go almost to get to Go again--and a million million rules of the game to keep in mind. Well, here's this one little guy and every morning he wakes up there's all these things he's got to keep in mind to do or he'll lose his turn three times in a row and maybe a terrible black rook in iron armor'll loom up and bang him off the chessboard. But now, look, now he's got his tickler and he tells his sweet silver tickler all these things and the tickler's got to remember them. Of course he'll have to do them eventually but meanwhile the pressure's off him, the hook's out of his short hairs.

He's shifted the responsibility...."

"Well, what's so bad about that?" Fay broke in loudly. "What's wrong with taking the pressure off little guys? Why shouldn't Tickler be a super-ego surrogate? Micro's Motivations chief noticed that positive feature straight off and scored it three pluses. Besides, it's nothing but a gaudy way of saying that Tickler backstops the memory.

Seriously, Gussy, what's so bad about it?"

"I don't know," Gusterson said slowly, his eyes still far away. "I just know it feels bad to me." He crinkled his big forehead. "Well for one thing," he said, "it means that a man's taking orders from something else. He's got a kind of master. He's sinking back into a slave psychology."

"He's only taking orders from himself," Fay countered disgustedly.

"Tickler's just a mech reminder, a notebook, in essence no more than the back of an old envelope. It's no master."

"Are you absolutely sure of that?" Gusterson asked quietly.

"Why, Gussy, you big oaf--" Fay began heatedly. Suddenly his features quirked and he twitched. "'Scuse me, folks," he said rapidly, heading for the door, "but my tickler told me I gotta go."

"Hey Fay, don't you mean you told your tickler to tell you when it was time to go?" Gusterson called after him.

Fay looked back in the doorway. He wet his lips, his eyes moved from side to side. "I'm not quite sure," he said in an odd strained voice and darted out.

Gusterson stared for some seconds at the pattern of emptiness Fay had left. Then he shivered. Then he shrugged. "I must be slipping," he muttered. "I never even suggested something for him to invent." Then he looked around at Daisy, who was still standing poker-faced in her doorway.

"Hey, you look like something out of the Arabian Nights," he told her.

"Are you supposed to be anything special? How far do those stripes go, anyway?"

"You could probably find out," she told him coolly. "All you have to do is kill me a dragon or two first."

He studied her. "My G.o.d," he said reverently, "I really have all the fun in life. What do I do to deserve this?"

"You've got a big gun," she told him, "and you go out in the world with it and hold up big companies and take yards and yards of money away from them in rolls like ribbon and bring it all home to me."

"Don't say that about the gun again," he said. "Don't whisper it, don't even think it. I've got one, dammit--thirty-eight caliber, yet--and I don't want some psionic monitor with two-way clairaudience they haven't told me about catching the whisper and coming to take the gun away from us. It's one of the few individuality symbols we've got left."

Suddenly Daisy whirled away from the door, spun three times so that her silvered hair stood out like a metal coolie hat, and sank to a curtsey in the middle of the room.

"I've just thought of what I am," she announced, fluttering her eyelashes at him. "I'm a sweet silver tickler with green stripes."

Next day Daisy cashed the Micro check for ten hundred silver smackers, which she hid in a broken radionic coffee urn. Gusterson sold his insanity novel and started a new one about a mad medic with a hiccupy hysterical chuckle, who gimmicked Moodmasters to turn mental patients into nymphomaniacs, ma.s.s murderers and compulsive saints. But this time he couldn't get Fay out of his mind, or the last chilling words the nervous little man had spoken.

For that matter, he couldn't blank the underground out of his mind as effectively as usually. He had the feeling that a new kind of mole was loose in the burrows and that the ground at the foot of their skysc.r.a.per might start humping up any minute.

Toward the end of one afternoon he tucked a half dozen newly typed sheets in his pocket, shrouded his typer, went to the hatrack and took down his prize: a miner's hard-top cap with electric headlamp.

"Goin' below, Cap'n," he shouted toward the kitchen.

"Be back for second dog watch," Daisy replied. "Remember what I told you about la.s.soing me some art-conscious girl neighbors."

"Only if I meet a piebald one with a taste for Scotch--or maybe a pearl gray biped jaguar with violet spots," Gusterson told her, clapping on the cap with a We-Who-Are-About-To-Die gesture.

Halfway across the park to the escalator bunker Gusterson's heart began to tick. He resolutely switched on his headlamp.

As he'd known it would, the hatch robot whirred an extra and higher-pitched ten seconds when it came to his topside address, but it ultimately dilated the hatch for him, first handing him a claim check for his ID card.

Gusterson's heart was ticking like a sledgehammer by now. He hopped clumsily onto the escalator, clutched the moving guard rail to either side, then shut his eyes as the steps went over the edge and became what felt like vertical. An instant later he forced his eyes open, unclipped a hand from the rail and touched the second switch beside his headlamp, which instantly began to blink whitely, as if he were a civilian plane flying into a nest of military jobs.

With a further effort he kept his eyes open and flinchingly surveyed the scene around him. After zigging through a bombproof half-furlong of roof, he was dropping into a large twilit cave. The blue-black ceiling twinkled with stars. The walls were pierced at floor level by a dozen archways with busy niche stores and glowing advertis.e.m.e.nts crowded between them. From the archways some three dozen slidewalks curved out, tangenting off each other in a bewildering multiple cloverleaf. The slidewalks were packed with people, traveling motionless like purposeful statues or pivoting with practiced grace from one slidewalk to another, like a thousand toreros doing veronicas.

The slidewalks were moving faster than he recalled from his last venture underground and at the same time the whole pedestrian concourse was quieter than he remembered. It was as if the five thousand or so moles in view were all listening--for what? But there was something else that had changed about them--a change that he couldn't for a moment define, or unconsciously didn't want to.

Clothing style? No ... My G.o.d, they weren't all wearing identical monster masks? No ... Hair color?... Well....

He was studying them so intently that he forgot his escalator was landing. He came off it with a heel-jarring stumble and b.u.mped into a knot of four men on the tiny triangular hold-still. These four at least sported a new style-wrinkle: ribbed gray shoulder-capes that made them look as if their heads were poking up out of the center of bulgy umbrellas or giant mushrooms.

One of them grabbed hold of Gusterson and saved him from staggering onto a slidewalk that might have carried him to Toledo.

"Gussy, you dog, you must have esped I wanted to see you," Fay cried, patting him on the elbows. "Meet Davidson and Kester and Hazen, colleagues of mine. We're all Micro-men." Fay's companions were staring strangely at Gusterson's blinking headlamp. Fay explained rapidly, "Mr. Gusterson is an insanity novelist. You know, I-D."

"Inner-directed spells _id_," Gusterson said absently, still staring at the interweaving crowd beyond them, trying to figure out what made them different from last trip. "Creativity fuel. Cranky. Explodes through the parietal fissure if you look at it cross-eyed."

"Ha-ha," Fay laughed. "Well, boys, I've found my man. How's the new novel perking, Gussy?"

"Got my climax, I think," Gusterson mumbled, still peering puzzledly around Fay at the slidestanders. "Moodmaster's going to come alive.

Ever occur to you that 'mood' is 'doom' spelled backwards? And then...." He let his voice trail off as he realized that Kester and Davidson and Hazen had made their farewells and were sliding into the distance. He reminded himself wryly that n.o.body ever wants to hear an author talk--he's much too good a listener to be wasted that way.

Let's see, was it that everybody in the crowd had the same facial expression...? Or showed symptoms of the same disease...?

"I was coming to visit you, but now you can pay me a call," Fay was saying. "There are two matters I want to--"

Gusterson stiffened. "My G.o.d, _they're all hunchbacked_!" he yelled.

"Shh! Of course they are," Fay whispered reprovingly. "They're all wearing their ticklers. But you don't need to be insulting about it."

"_I'm gettin' out o' here._" Gusterson turned to flee as if from five thousand Richard the Thirds.

"Oh no you're not," Fay amended, drawing him back with one hand.

Somehow, underground, the little man seemed to carry more weight.

"You're having c.o.c.ktails in my thinking box. Besides, climbing a down escaladder will give you a heart attack."
