perhaps have no right to bring up. But my wife
is greatly worried about this plague. I violate no confidence in telling
you there is considerable unease, even on Earth, according to messages I
have received. The ship physician believes Mrs. Everts may have the
plague, but isn't sure of the symptoms. I understand you are quite
expert."

Doc wondered about the physician. Apparently there was another man who
placed his patients above anything else, though he was probably
meticulous about obeying all actual rules. There was no law against
listening to a pariah, at least.

"When did she have Selznik's migraine?" he asked.

"About thirteen years ago. We went through it together, shortly after
having our metabolism switched during the food shortage of '88."

Doc felt carefully at the base of the Captain's skull; the swelling was
there. He asked a few questions, but there could be no doubt.

"Both of you must have it, Captain, though it won't mature for another
year. I'm sorry."

"There's no hope, then?"

Doc studied the man. But Everts wasn't the sort to dicker even for his

working on it. Perhaps if I could leave a few notes for your
physician--"

It was Everts' turn to shake his head. "I'm sorry, Dr. Feldman. I have
orders to burn out your cabin when you leave. But thank you." He got to
his feet and left as quietly and erectly as he had entered.

Doc tore up his notes bitterly. He paced his cabin slowly, reading out
the hours while his eyes lingered on the little bottle of cultures. At
times the fear grew in him, but he mastered it. There was half an hour
left when he began opening the little bottles and making his films.

He was still not finished when steps echoed down the hall, but he was
reasonably sure of his results. The bug could not grow in Earth-normal
tissue.

Three men entered the room. One of them, dressed in a spacesuit, held
out another suit to him. The other two began gathering up everything in
the cabin and stowing it neatly into a sack designed to protect freight
for a limited time in a vacuum.

Doc forced his hands to steadiness with foolish pride and began climbing
into the suit. He reached for the helmet, but the man shook his head,
pointing to the oxygen gauge. There would be exactly one hour's supply
of oxygen when he was thrown out and it still lacked five minutes of the
deadline.

They marched him down the hallway, t
