"I haven't time to explain," I said in a low voice, afraid of waking Hallam.

She suspected as much. "Have you told the Chief?"

"No, I don't want to tell him just now. I've got a hunch on this virus warfare idea of his. It's only a wild guess and I've got to go out to follow it up. He might not want me to take the risk of catching flu."

"I don't want you to either."

"I'm sorry, Honey, but I've got to do it. There's too much riding on this thing to let our personal affairs interfere."

"But you said yourself it's only a wild guess. Why risk our whole future on that?"

"Look, I'm going to keep away from people as much as possible, but I'm going out just the same. This may be the last chance I'll ever get to see if the boss is right."

"Then I'm going with you."

"Oh, hell! This is no job for a woman."

"It's no job for one man! Either I go or I wake up Dr. Hallam."
