i is on the roof."

"Very good." Morely nodded shortly and took his notebook from his
pocket. "We'll go to Building Seven Twenty-three."

He turned and walked toward the self-service elevator. Bond hurried a
little to open the door for him.

Bond eased the helicopter neatly through the entry slot and on down into
one of the empty visitor spaces in the landing area at Block 1022. The
two men walked across the areaway to an entrance.

As they went up the short flight of stairs into the hall, Morely took
careful notice of the building. The mosaic tile of the stairs and floor
gleamed from a recent scrubbing. The plastic and metal handrails were
spotless. He looked briefly at his subordinate, then motioned toward the
door at their right.

"This one," he ordered.

Bond touched the call button and they waited.

From inside the apartment, there was a slight rustle of motion, then the

"Pull the drip pan," he ordered.

Graham came forward and pulled a flat sheet from the range, then opened
an access door at the front of the stove.

Morely peered inside, then thrust a hand in. For a moment, he groped
around, then he pulled his hand out and looked at it. It was clean. He
sniffed at his fingers, then turned away.

"You may replace the pan, Fellow." He went into the living room, noting
that the woman and three children were neat and in the proper attitudes
of attention. One of the children was looking at him, wide-eyed. He saw
that the child was clean and apparently healthy.

In addition to the usual chairs, table, and divan, there were some
bookcases which formed a small alcove around a combination desk and
drawing table. Morely circled the bookcases, to stand before the desk.

"What's this?" he demanded. He turned to a bookcase, to examine the
titles.

Most of the books were engineering texts and reference works. There
were some standard works of philo
