h is the case," said Ali-Tomas, "we must make our arrangements
for your care on a long-term basis."

Ali made a gesture. Hands seized Murphy's shoulders. A respirator was
held to his nostrils. He thought of his camera, and he could have
laughed. Mystery! Excitement! Thrills! Dramatic sequence for _Know Your
Universe!_ Staff-man murdered by fanatics! The crime recorded on his own
camera! See the blood, hear his death-rattle, smell the poison!

The vapor choked him. _What a break! What a sequence!_

"Sirgamesk," said Howard Frayberg, "bigger and brighter every minute."

"It must've been just about in here," said Catlin, "that Wilbur's
horseback rider appeared."

"That's right! Steward!"

"Yes, sir?"

"We're about twenty thousand miles out, aren't we?"

"About fifteen thousand, sir."

"Sidereal Cavalry! What an idea! I wonder how Wilbur's making out on his
superstition angle?"

Sam Catlin, watching out the window, said in a tight voice, "Why not ask

Said Frayberg, "That's not a horse he's riding. It's a combination
ram-jet and kiddie car with stirrups!"

"He's coming aboard the ship," said Catlin. "That's the entrance port
down there...."

Wilbur Murphy sat in the captain's stateroom, taking careful breaths of
air.

"How are you now?" asked Frayberg.

"Fine. A little sore in the lungs."

"I shouldn't wonder," the ship's doctor growled. "I never saw anything
like it."

"How does it feel out there, Wilbur?" Catlin asked.

"It feels awful lonesome and empty. And the breath seeping up out of
your lungs, never going in--that's a funny feeling. And you miss the air
blowing on your skin. I never realized it before. Air feels like--like
silk, like whipped cream--it's got texture...."

"But aren't you cold? Space is supposed to be absolute zero!"

"Space is nothing. It's not hot and it's not cold. When you're in the
sunlight you get warm. It's better in the shade. You don't lose any heat
by air convection, but radiation and sweat evaporation keep you
comfortably cool."

"I s
