n his luxurious hotel room Bryce checked his watch. Eight o'clock. A telephone call was scheduled for some time in the half hour. He filed the question of who was behind the night's attack and picked up the phone. The dial system was in automatic contact with any city in the world. He dialed.

Somewhere in a city, a phone rang. It rang unheard, for it was locked into a safe in a tiny rented office with some unusual mechanisms attached. The ringing was stopped abruptly and a recorded voice answered, "Yeah?"

Bryce took a dial phone from the night table where it had been sitting innocently like a toy he had bought for some child. "Hi Al," he said cheerfully to the automatic mechanism at the other end. "Listen, I think I've got a new phrase for that transition theme. How's this?" He put the receiver against the back of the toy and dialed the toy dial. It responded to each letter and number with a ringing note of different pitch that played a short unmelodious tune.

The pitch notes went over the line and entered the mechanism, making the contacts within it that dialed the number he had dialed on the toy phone.

"How's that?" Bryce said cheerfully.

The recorded voice said, "Sounds good. I'll see what I can do with it." Somewhere far away and unheard another phone had begun to ring. "Want to speak to George?"

"Sure."

A phone rang in a pay booth somewhere in a great city railroad station, and someone browsing at a magazine stand or sitting on a suitcase apparently waiting for a train strolled casually to answer it.

"Hello?" said a noncommittal voice, prepared to claim that he was merely a stranger answering the phone because it was ringing in public.
