The Mermaid Tavern had been elaborately decorated. Great blocks of hewn coral for pillars and booths, tarpon and barracuda on the walls, murals of Neptune and his court—including an outsize animated picture of a mermaid ballet, quite an eye-catcher. But the broad quartz windows showed merely a shifting greenish-blue of seawater, and the only live fish visible were in an aquarium across from the bar. Pacific Colony lacked the grotesque loveliness of the Florida and Cuba settlements. Here they were somehow a working city, even in their recreations.

The sensitive man paused for a moment in the foyer, sweeping the big circular room with a hurried glance. Less than half the tables were filled. This was an hour of interregnum, while the twelve to eighteen hundred shift was still at work and the others had long finished their more expensive amusements. There would always be a few around, of course—Dalgetty typed them as he watched.

A party of engineers, probably arguing about the compression strength of the latest submarine tank to judge from the bored expressions of the three or four rec girls who had joined them. A biochemist, who seemed to have forgotten his plankton and seaweed for the time being and to have focussed his mind on the pretty young clerk with him. A couple of hard-handed caissoniers, settling down to some serious drinking.

A maintenance man, a computerman, a tank pilot, a diver, a sea rancher, a bevy of stenographers, a bunch of very obvious tourists, more chemists and metallurgists—the sensitive man dismissed them all. There were others he couldn't classify with any decent probability but after a second's hesitation he decided to ignore them too. That left only the group with Thomas Bancroft.

They were sitting in one of the coral grottos, a cave of darkness to ordinary vision. Dalgetty had to squint to see in and the muted light of the tavern was a harsh glare when his pupils were so distended. But, yes—it was Bancroft all right and there was an empty booth adjoining his.

Dalgetty relaxed his eyes to normal perception. Even in the short moment of dilation the fluoros had given him a headache. He blocked it off from consciousness and started across the floor.

A hostess stopped him with a touch on the arm as he was about to enter the vacant cavern. She was young, an iridescent mantrap in her brief uniform. With all the money flowing into Pacific Colony they could afford decorative help here.

"I'm sorry, sir," she said. "Those are kept for parties. Would you like a table?"

"I'm a party," he answered, "or can soon become one." He moved aside a trifle so that none of the Bancroft group should happen to look out and see him. "If you could arrange some company for me...." He fumbled out a C-note, wondering just how such things could be done gracefully.

"Why, of course, sir." She took it with a smoothness he envied and handed him a stunning smile in return. "Just make yourself comfortable."

Dalgetty stepped into the grotto with a fast movement. This wasn't going to be simple. The rough red walls closed in on top of him, forming a space big enough for twenty people or so. A few strategically placed fluoros gave an eerie undersea light, just enough to see by—but no one could look in. A heavy curtain could be drawn if one wanted to be absolutely secluded. Privacy—uh-huh!

He sat down at the driftwood table and leaned back against the coral. Closing his eyes he made an effort of will. His nerves were already keyed up to such a tautness that it seemed they must break and it took only seconds to twist his mind along the paths required.

The noise of the tavern rose from a tiny mumble to a clattering surf, to a huge and saw-edged wave. Voices dinned in his head, shrill and deep, hard and soft, a senseless stream of talking, jumbled together into words, words, words. Somebody dropped a glass and it was like a bomb going off.

Dalgetty winced, straining his ear against the grotto side. Surely enough of their speech would come to him, even through all that rock! The noise level was high but the human mind, if trained in concentration, is an efficient filter. The outside racket receded from Dalgetty's awareness and slowly he gathered in the trickle of sound.

First man: "—no matter. What can they do?"

Second man: "Complain to the government. Do you want the FBI on our trail? I don't."

First man: "Take it easy. They haven't yet done so and it's been a good week now since—"

Second man: "How do you know they haven't?"

Third man—heavy, authoritative voice. Yes, Dalgetty remembered it now from TV speeches—it was Bancroft himself: "I know. I've got enough connections to be sure of that."

Second man: "Okay, so they haven't reported it. But why not?"

Bancroft: "You know why. They don't want the government mixing into this any more than we do."

Woman: "Well, then, are they just going to sit and take it? No, they'll find some way to—"

"HELLO, THERE, MISTER!!!"

Dalgetty jumped and whirled around. His heart began to race, until he felt his ribs tremble and he cursed his own tension.

"WHY, WHAT'S THE MATTER, MISTER? YOU LOOK—"

Effort again, forcing the volume down, grasping the thunderous heart in fingers of command and dragging it toward rest. He focussed his eyes on the girl who had entered. It was the rec girl, the one he had asked for because he had to sit in this booth.

Her voice was speaking on an endurable level now. Another pretty little bit of fluff. He smiled shakily. "Sit down, sweet. I'm sorry. My nerves are shot. What'll you have?"

"A daiquiri, please." She smiled and placed herself beside him. He dialed on the dispenser—the cocktail for her, a scotch and soda for himself.

"You're new here," she said. "Have you just been hired or are you a visitor?" Again the smile. "My name's Glenna."

"Call me Joe," said Dalgetty. His first name was actually Simon. "No, I'll only be here a short while."

"Where you from?" she asked. "I'm clear from New Jersey myself."

"Proving that nobody is ever born in California." He grinned. The control was asserting itself, his racing emotions were checked and he could think clearly again. "I'm—uh—just a floater. Don't have any real address right now."

The dispenser ejected the drinks on a tray and flashed the charge—$20. Not bad, considering everything. He gave the machine a fifty and it made change, a five-buck coin and a bill.

"Well," said Glenna, "here's to you."

"And you." He touched glasses, wondering how to say what he had to say. Damn it, he couldn't sit here just talking or necking, he'd come to listen but.... A sardonic montage of all the detective shows he had ever seen winked through his mind. The amateur who rushes in and solves the case, heigh-ho. He had never appreciated all the detail involved till now.

There was hesitation in him. He decided that a straightforward approach was his best bet. Deliberately then he created a cool confidence. Subconsciously he feared this girl, alien as she was to his class. All right, force the reaction to the surface, recognize it, suppress it. Under the table his hands moved in the intricate symbolic pattern which aided such emotion-harnessing.

"Glenna," he said, "I'm afraid I'll be rather dull company. The fact is I'm doing some research in psychology, learning how to concentrate under different conditions. I wanted to try it in a place like this, you understand." He slipped out a 2-C bill and laid it before her. "If you'd just sit here quietly it won't be for more than an hour I guess."

"Huh?" Her brows lifted. Then, with a shrug and a wry smile, "Okay, you're paying for it." She took a cigarette from the flat case at her sash, lit it and relaxed. Dalgetty leaned against the wall and closed his eyes again.

The girl watched him curiously. He was of medium height, stockily built, inconspicuously dressed in a blue short-sleeved tunic, gray slacks and sandals. His square snub-nosed face was lightly freckled, with hazel eyes and a rather pleasant shy smile. The rusty hair was close-cropped. A young man, she guessed, about twenty-five, quite ordinary and uninteresting except for the wrestler's muscles and, of course, his behavior.

Oh, well, it took all kinds.

Dalgetty had a moment of worry. Not because the yarn he had handed her was thin but because it brushed too close to the truth. He thrust the unsureness out of him. Chances were she hadn't understood any of it, wouldn't even mention it. At least not to the people he was hunting.

Or who were hunting him?

Concentration, and the voices slowly came again: "—maybe. But I think they'll be more stubborn than that."

Bancroft: "Yes. The issues are too large for a few lives to matter. Still, Michael Tighe is only human. He'll talk."

The woman: "He can be made to talk, you mean?" She had one of the coldest voices Dalgetty had ever heard.

Bancroft: "Yes. Though I hate to use extreme measures."

Man: "What other possibilities have we got? He won't say anything unless he's forced to. And meanwhile his people will be scouring the planet to find him. They're a shrewd bunch."

Bancroft, sardonically: "What can they do, please? It takes more than an amateur to locate a missing man. It calls for all the resources of a large police organization. And the last thing they want, as I've said before, is to bring the government in on this."

The woman: "I'm not so sure of that, Tom. After all, the Institute is a legal group. It's government sponsored and its influence is something tremendous. Its graduates—"

Bancroft: "It educates a dozen different kinds of psychotechnicians, yes. It does research. It gives advice. It publishes findings and theories. But believe me the Psychotechnic Institute is like an iceberg. Its real nature and purpose are hidden way under water. No, it isn't doing anything illegal that I know of. Its aims are so large that they transcend law altogether."

Man: "What aims?"

Bancroft: "I wish I knew. We've only got hints and guesses, you know. One of the reasons we've snatched Tighe is to find out more. I suspect that their real work requires secrecy."

The woman, thoughtfully: "Y-y-yes, I can see how that might be. If the world at large were aware of being—manipulated—then manipulation might become impossible. But just where does Tighe's group want to lead us?"

Bancroft: "I don't know, I tell you. I'm not even sure that they do want to—take over. Something even bigger than that." A sigh. "Let's face it, Tighe is a crusader too. In his own way he's a very sincere idealist. He just happens to have the wrong ideals. That's one reason why I'd hate to see him harmed."

Man: "But if it turns out that we've got to—"

Bancroft: "Why, then we've got to, that's all. But I won't enjoy it."

Man: "Okay, you're the leader, you say when. But I warn you not to wait too long. I tell you the Institute is more than a collection of unworldly scientists. They've got someone out searching for Tighe and if they should locate him there could be real trouble."

Bancroft, mildly: "Well, these are troubled times, or will be shortly. We might as well get used to that."

The conversation drifted away into idle chatter. Dalgetty groaned to himself. Not once had they spoken of the place where their prisoner was kept.

All right, little man, what next? Thomas Bancroft was big game. His law firm was famous. He had been in Congress and the Cabinet. Even with the Labor Party in power he was a respected elder statesman. He had friends in government, business, unions, guilds and clubs and leagues from Maine to Hawaii. He had only to say the word and Dalgetty's teeth would be kicked in some dark night. Or, if he proved squeamish, Dalgetty might find himself arrested on a charge like conspiracy and tied up in court for the next six months.

By listening in he had confirmed the suspicion of Ulrich at the Institute that Thomas Bancroft was Tighe's kidnapper—but that was no help. If he went to the police with that story they would (a) laugh, long and loud—(b) lock him up for psychiatric investigation—(c) worst of all, pass the story on to Bancroft, who would thereby know what the Institute's children could do and would take appropriate counter-measures.
