He said, "If I hadn't I'd probably never have seen you again."

She collapsed into his arms.

Later--much later--as Nina was about to leave him for her own suite, he

asked, "Honeycomb, what did you lose that caused Fernando to give you

that necklace?"

"I nearly lost you," she replied from the doorway. "I bet him Maria

wouldn't get you that night. And lost. So Fernando sent the necklace as

compensation."

"Quite a large compensation," said Lindsay drily.

Nina shrugged. "Not for Fernando," she told him. "After all, I pay him

enough. He's my number one political boy. 'Night, darling."

Lindsay was on the verge of a breakdown himself by noon the next day,

after Computation Minister du Fresne, looking uglier than ever, had

finished conducting President Giovannini's official party through the

rooms and passages of Giac. If Nina hadn't been by his side during and

after the swift rocket trip to Death Valley, he might have collapsed.

It was she who had removed the glittering star from his breast before

breakfast in the Sherwood Forest mansion that morning. "You needed

something to wear for show last night," she had told him.

"Then it's not mine?" he had countered absently.

"Of course it is," she had assured him. "But Secretary General Bergozza

is going to make the official investiture after the test."

Lindsay had meekly surrendered the bauble, barely noticing. His brain

was straining to recall what he could of symbolic logic--a subject that

had never particularly interested him. For some reason it kept working

back to Lewis Carroll, who, under his real name of Charles Lutwidge

Dodgson, had been the founder of symbolic logic back in the nineteenth

century, along with the renowned Dr. Poole.

About all he could remember was the following problem:

(1) Every one who is sane can do Logic;

(2) No lunatics are fit to serve on a jury;

(3) None of _your_ sons can do Logic.

The Universal was "persons". The symbols were: a--able to do Logic;

b--fit to serve on a jury; c--sane; d--your sons.

And the answer, of course, was: None of _your_ sons is fit to serve on a

jury.

For some reason this, in turn, made him think of the ancient conundrum

that employed confusion to trip its victims: What's the difference

between an iron dog in the side yard of a man who wants to give his

little daughter music lessons but is afraid he can't afford them next

year, and a man who has a whale in a tank and wants to send him for a

wedding present and is trying to pin a tag on him, saying how long he

is, how much he weighs and where he comes from, but can't because the

whale keeps sloshing around in the tank and knocking the tag off?

This time, the answer was: One can't wag his tail, the other can't tag

his whale.

"None of _your_ sons is fit to tag a whale--or wag a tail," he said

absently.

"What was that?" Nina asked.

"Nothing, nothing at all," he replied. "Merely a man going out of his

mind."

"It will never miss you," she replied brightly. But her brightness

became a bit strained as the day wore on. The trip, for Lindsay, was

sheer nightmare. _No sane man can wag his tail_, he kept thinking.

Even such fugitive grasping at Logical straws vanished when he saw the

immense squat mass of Giac, rising like a steel-and-concrete toad from

the wastes of the California desert. It seemed absurd even to think that

such an imposing and complex structure should have been reared on the

mathematics of the immortal author of _Alice in Wonderland_, _Through

the Looking Glass_ and _The Hunting of the Snark_.

For Giac _was_ imposing, even to a man biased against computers from

birth. Nor did du Fresne's smugness help Lindsay's assurance a bit. He

explained how each of the block-large preliminary feeders worked--one

for mathematical symbols, one for oral recording, a third for written

exposition. Each worked simultaneously and in three different ways--via

drum-memory banks, via punched tapes, via the new "ear-tubes" that

responded to sound.

Then there were the preliminary synthesizers, each of which unified in

vapor-plutonium tubes the findings of its three separate feeders. Next,

a towering black-metal giant filling three walls of a cubical room

twenty metres in each dimension, came the final synthesizer, which

coordinated the findings of the preliminary synthesizers and fed them

into Giac itself.

The master machine was the least imposing of all. It stood like an

alabaster stele in the center of an immense chamber arranged like a

theater-in-the-round. But du Fresne, peering through his strawberry

spectacles, said gloatingly, "Don't be deceived by the size, ladies and

gentlemen. All but what you see of Giac is underground. It is contained

in an all-metal cell one million cubic metres in volume. And it is

infallible."

Fortunately Lindsay was given a half hour of final preparation in one of

the small offices with which the above-ground building was honeycombed.

Nina came with him--by request.

"I can't do it," he told her abruptly.

"Don't worry, darling, you'll think of something," she said. She tried

to embrace him but he was too worried to respond. After awhile she said,

"Why not put a direct question. Ask it if it's infallible."

"It could hardly tell a lie on itself," he replied.

"What if such a question involved destruction of part of itself in the

answer?" she asked.

"It might--though I presume du Fresne and his boys have prepared it for

such jokers. And anyway, what sort of question would do that? Got any

ideas?"

"That's your department," she said helpfully. "You're the computer

smasher of this team."

"But that was pure luck," he said half-angrily. "One can't wag his

tail.... The other can't serve on a jury."
