Blair Freedman stood rigidly before the desk, arms at his sides, eyes on Peter Folley. Folley didn't look up. He gripped Freedman's release papers in his hand. He wasn't reading them.

"So you came back?"

Freedman didn't answer.

"I suppose on account of Jerry, huh?" Folley said. "You were talking to Jerry just before he died, they said."

Freedman found his voice.

"I tried to warn him."

Folley nodded slightly.

"If you had been with him, you'd have known the tunnel head was blocked. You had that gift, the sense of feeling pressure changes. You would have saved Jerry."

Freedman didn't answer. He had left the Warrior Patrol and come back to his old job again. He had to carry on for Jerry Graham.
