orning, Jones."

"Good morning, Doctor. Pretty early, aren't you?"

"Wednesday's my busy day." He settled at his desk, miserably conscious
of the open door and curious eyes behind him, opened his briefcase, then
glanced at his wristwatch. More than an hour before his interview with
Leader Marley.

Spreading some data sheets before him, he looked at them blankly as he
tried to order his thoughts. His eyes were ringed with dark depressions,
for he had had no sleep. There had been so many things to plan for, so
many arrangements to make.

It was possible, of course, that this morning's talk would turn out to
be mere routine. There might remain several weeks of freedom--but there
might be only a few hours. He shrank from the complexity of the problem
before him; he was a Research man, devoted to his test tubes and his
culture growths, and would have been happy never to face any problem
beyond them.

He had a moment's revulsion at the unfairness of the fact that a simple

sank down into her chair by the stenograph.

"You doublecrosser!" she whispered.

He looked quickly at the doorway, but the guard had not come back.
Leaning forward, he questioned her fiercely.

"What are you doing here? They told me yesterday that several people had
come down with attacks of Blue Martian. Why aren't you in the hospital
with the others?"

"Because I wasn't sick!"

"But I gave you--"

"Imagine how I felt," she raced on, "watching Dr. Haslam start having a
chill, hearing Dr. Faure complain about his awful headache, and
listening to Dr. Hudson dial Intercom and call for a doctor. And all
that time I was waiting, waiting for something to happen to me. And
nothing did! What have you got against me, Dr. Wong, that you infect all
the others and only pr
