Abruptly the alarm stopped. The silence was hard to bear.

May swallowed and went on: "—for some reason or other. Why don't youngsters elect for Controller any more? Why didn't you, for instance?"

Reuben wished he could be saved by a direct hit. The binoculars, Selene, the raid, and now he was supposed to make intelligent conversation with a general.

"I really don't know, sir," he said miserably. "At the time there seemed to be very little difference—Controller, Atomist, Missiler, Maintainer. We have a saying, 'The buttons are different,' which usually ends any conversation on the subject."

"Indeed?" asked May distractedly. His face was thinly filmed with sweat. "Do you suppose Ellay intends to clobber us this time?" he asked almost hoarsely. "It's been some weeks since they made a maximum effort, hasn't it?"

"Four," said Reuben. "I remember because one of my best Servers was killed by a falling corridor roof—the only fatality and it had to happen to my team!"

He laughed nervously and realized that he was talking like a fool, but May seemed not to notice.

Far below them, there was a series of screaming whistles as the interceptors were loosed to begin their intricate, double basketwork wall of defense in a towering cylinder about Denv.

"Go on, Reuben," said May. "That was most interesting." His eyes were searching the underside of the steel table.

Reuben averted his own eyes from the frightened face, feeling some awe drain out of him. Under a table with a general! It didn't seem so strange now.
