"Going to Earth. I'll be going with them, of course, to lead the raid. Or I should say, ahead of them. They'll wait in space until they get my signal. You could come back with me, if you decide to help."
Again, on a note of desperation, Birrel said, "I've got to think."
They took him back to the car and through the tunnel and into the building again. There guards took him upstairs and placed him in a small square room without even slits in the wall, furnished with a bed, a table, and a chair. They locked the door and left him alone there, with nothing to do and nothing to see, and nothing even to hear but the soft blowing of air through an iron-barred duct in the ceiling.
Maximum security, and no distractions. In this place a man couldn't do anything but think.
Food was brought. The guard who brought it admitted it was now night outside, but he refused to say anything about Kara and Thile, where they were or if they were still alive.
Birrel ate. A little after that the lights went off. He groped his way to the bed and lay down, trying to see a way out, a way to help Thile and Kara and stop the evil that was about to be done, and seeing only darkness.
Eventually, without meaning to, he fell asleep.
He was wakened by a sound. It was a very slight sound, and it took him a minute to identify it as the clink and creak of an iron grating being moved. By that time it was too late.
Somebody was already in the dark room, and before Birrel could call out a man's body was on top of him and strong hands were fastening on his throat.
