ith a harsh laugh.

"Come here spying," he said, "and tell me you want to get away from
the world." Again he laughed shrilly.

"And I am going to be your little fairy godmother. I wish you were
Goodwin himself! I wish I had him here. But you'll get your
wish--you'll get your wish. You'll leave the world, you shall,
indeed."

He rocked back and forth with appreciation of his humor.

"Didn't know I was all ready to leave, did you? All packed and ready
to go. Supplies all stowed away; enough energy stored to carry me
millions of miles. Or maybe you did know--maybe there are others
coming...." He hurried across the room to open a heavy door of split
logs in the rock wall.

"I'll fool them all this time," he said; "and you'll never go back to
tell them." The door closed behind him.

"Crazy as a bed-bug," Jerry told himself. He strained frantically at
the ropes that bound him. "Looks bad for me: the old bird said I'd
never go back. Well, what if I die now ... or six months from now?
Though I know that doctor was wrong."

He tried to accept his fate philosophically, but the will to live was
strong. And one of his wrists felt looser in its bonds.

Across the room his pack lay on the floor, and in it was a heavy
forty-five. If he could get the pistol.... A knot pulled loose under
his twisting fingers. One hand was free. He worked feverishly at the
other wrist.

The ropes were suddenly loose. He pulled himself to his feet, took a
moment to regain control of cramped muscles, then flung himself at the
pack. When the heavy door opened he was behind it, his pistol in his
hand.

There was no struggle: the lanky figure showed no maniacal fury.
Instead, the man did a surprising thing. He sank weakly upon the rough
bunk where Jerry had lain, his face buried in his thin hands.

"I should have let you die," he said slowly, hopelessly. "I should
have let you die. But I couldn't do that.... And now you'll steal my
invention for Goodwin."

Jerry was as exasperated as he was amazed.

"I told you," he almost shouted. "I never knew anyone named Goodwin! I
don't care a hoot about your invention. And as for letting me die--why
didn't you? That's a puzzle: you were about to kill me, anyway."

"No," said the other patiently. "I wasn't going to kill you."

"You said I'd never go back."

"I was going to take you with me."

"Take me where?"

"To the moon," said the drooping figure.
