Publisher's Synopsis
"From beyond the closed door of the room, a high-pitched humming was barely audible. It grew in volume, going up the scale. Terri leaped to his feet; and for the space of a couple of seconds, he lunged first this way then that, like a wild animal beating against its trap. Then, as if all will had at last gone out of him, he stopped in the middle of the room and closed his eyes. For a fraction of a moment he stood there, before a faint convulsion seized him and he fell."
