The plague speeded up again. About four people out of a hundred now seemed to have caught the disease and cured themselves. They accounted for what faith was left in Doc's plasma and gave some unfounded hope to the others.

Northport fell a week later, putting the whole planet in rebel hands.

Jake returned, wearier than ever. He'd proved to be one of the natural immunes, but the weight of the campaign that could only end in a defeat by the plague left him no room to rejoice in his personal fortune.

This time he looked completely defeated. And a moment later, Doc saw why as Jake flipped a flimsy sheet onto the table. It bore the seals of Space and Medical Lobbies.

Jake pointed upwards. "The war rockets are there, all right. We knew they'd come. Now all they want for calling them off is our surrender and your cure. If they don't get both, they'll blow the planet to bits. We have two days."

The rockets could be seen clearly with binoculars. There were more than enough to destroy all life on the planet. Maybe they'd be used eventually, anyhow, since the Lobbies wanted no more rebellion. But with a cure for the plague, he might have bought them off.

Chris stood beside him, looking as if it were a bitter pill for her, too. She'd risked herself in the hands of the enemy, had cooperated with him in everything she'd been taught to oppose, and had worked like a dog. Now the Lobbies seemed to forget her as a useless tool. They were falling back on a raw power play and forgetting any earlier schemes.

"Maybe they'd hold off for a while if I agreed to go to them and share all my ideas, specimens and notes," he said at last. "Do you think your Lobby would settle for that, Chris?"

"I don't know, Dan. I've stopped thinking their way." She seemed almost apologetic for the admission.

He dropped an arm over her shoulder and turned with her back to the laboratory. "Okay, then we've got to find a miracle. We've got two days ahead of us. At least we can try."
