hane rapidly explained that he was going back into his own identity, and that some of the equipment present would help accelerate the change-over. He tried to give Astrid the general picture as they made the circuit changes on the equipment.

"Astrid, you are going to turn me in. You are going to surrender me to the Onzarians when they get here."

Astrid stopped. She had been re-fusing a circuit, and the fuse hung limply in her hand, forgotten.

Thane went on. "I'll explain while we finish the circuit. We haven't much time. You remember how we talked of driving the cork into the bottle? Well, that's what we're going to do. The Onzarians will be here before long when they've discovered their cruiser is missing. You will pass as an Onzarian. As an acolyte of the religion, you'll turn me over to them as a spy."

They had finished the identity accelerator circuit. Thane wasn't sure the rough equipment would do, but it might be close enough. He'd try it. He climbed on to the laboratory table and showed Astrid how to make the connections.

"I'm using all the power we have," he said. "I'll be out about 13 minutes, absolute. If they get here before then do everything you can to keep them out till the time's up."

Astrid looked down at him lying on the table. She was very serious, very quiet. She brushed her lips lightly against his forehead and said softly, "We'll manage."

She was gone and Thane heard the hum of power.

It went on and on, in the easy world of change. And then the power was gone. Thane struggled to open his eyes, minutes, years before he should. He looked up into the cold, unfriendly eyes of an Onzarian lieutenant.
