"This ship," Bairn put in, "cost billions; it meant the first real cooperative program the world's nations ever had. It would be ghastly if one man caused the destruction of Earth's last hope from doom. Wouldn't it, Joe?"

Joe's face was grim as he nodded.

"How would you feel if you were to blame for drowning out humanity, Joe?"

Joe stood up, and his body was shaking.

"Tell me, Joe," Bairn said quietly. "Why have you kept yourself from eating with the rest of the guys? Why is it when you come here you're always smelling of antiseptic?"

There were tears in Joe's brown eyes when he faced Bairn.

"Okay, John, what shall I do?"

"There's not much harm done yet? Arlie says that in the first stages, it's only communicable by contact. But once it gets past that first stage, it goes hog wild.

"Tell me, Joe, when did the nauseous attacks first come?"

Joe's brown eyes were dead. "Two days before the ship left."
