ifty years ago."

Hyrst said, "The Titanite? They said it hadn't ever been found. But how
it could have remained hidden so long--"

"I want you," Shearing said, "to tell me all about how MacDonald died.
Everything you can remember."

Hyrst asked eagerly, "You think we can find out who killed him? After
all this time? God, if we could--my son--"

"Quiet, Hyrst. Go ahead and tell me. Not in words. Just remember what
happened, and I'll get it."

Yet, by sheer lifetime habit, Hyrst could not remember without first
putting it into words in his own mind, as they two sat in the cold,
whispering darkness.

"There were four of us out there on Titan, you must already know that.
And only four--"

* * * * *

Four men. And one was named MacDonald, an engineer, a secretive, selfish
and enormously greedy man. MacDonald was the man who found a fortune,
and kept it secret, and died.

Landers was one. A lean, brown, lively man, an excellent physicist with
a friendly manner and no obvious ambitions.

Saul was one, and he was big and blond and quiet, a good drinking
companion, a good geologist, a lover of good music. If he had any darker
passions, he kept them hidden.

Hyrst was the fourth man, and the only one of the four still living....

He remembered now. He saw the black and bitter crags of Titan stark
against the glory of the Rings, and he saw two figures moving across a
plain of methane snow, their helmets gleaming in the Saturn-light.
Behind them in the plain were the flat, half-buried concrete structures
of the little refinery, and all around them were the spidery roads where
the big half-tracs dragged their loads of uranium ore from the
enchaining mountains.

The two men were quarrelling.

"You're angry," MacDonald was saying, "because it was _I_ who found it."

"Listen," Hyrst said. "We're sick, all three of us, of hearing you brag
about it."

"I'll bet you are," said MacDonald smugly. "The first find of a Titanite
pocket for years. The rarest, costliest stuff in the System. If you know
the way they've been bidding to buy it from me--"

"I do know," Hyrst said. "You've done nothing for weeks but give forth
mysterious hints--"

"And you don't like that," MacDonald said. "Of course you don't! It's no
part of our refinery deal, it's mine, I've got it and it's hidden where
nobody can find it till I sell it. Naturally, you don't like that."

"All _right_," said Hyrst. "So the Ti
