The mutape chattered suddenly and then stopped. Dr. Brooks bent and read out loud, "Get those two on motorskates! I know them. They appear blond with their projector fields turned on; otherwise they are both narrow-faced and dark."

Dr. Gesner smiled with just the middle of his face. "We caught them in the lobby on our way in. One of my lawyers is coming with us. His son plays right tackle—young lady!" He looked straight at Miss Knox. "I understand you've been talking about this business for days, along with our friend with the cut throat. You've been in danger—those two men were still in the building on your account, I'm sure. It's a very good thing you weren't alone, you or Dr. Brooks. I take it you were both on night duty."

Dr. Brooks said, "If any of the nurses or Dr. Gesner's students don't know what this is all about, I'm sure he'll make an announcement when we're all on the way to England. You must have some idea of what's happened. If anyone doesn't want to come, of course—"

"Treason and insubordination!" piped a hidden voice. "Under the circumstances, Dr. Hamilton will have you jailed when he finds out what you're up to, Dr. Brooks."

Brooks stretched his arm between two students and pulled a switch on the wall. The ceiling began to open, sweeping bright sunshine down the wall and making metal buttons twinkle on Dr. Feld's jacket. The ceiling slid back on rollers with a rumbling sound, until nothing was overheard but the black dots of aircraft rising toward the sun. Nearby, a whirlybird took off with a rackety-rackety-rackety-rack!

"I phoned the Director," Dr. Brooks told the crowd. "He's not interfering. In fact, I'm pretty sure Dr. Hamilton will come."

"Dr. Feld," said Dr. Gesner, "will you show the adman out?"

"I'm not—"

There was the sound of a blow and the assistant administrator appeared, scrabbling for his motorchair, which was buried among the students. His spindle limbs flailed from one side to the other until he was propelled from the room at a run, screaming, and the messenger boy vanished after him. Three bells rang in the corridor as the door closed.
