“It may be necessary for me to be away from the office at various times,” went on Bob, “but if I can’t get word to you, my uncle will see that you are advised.”

“Anything that really looks like a clue turned up?” asked Jacobs.

Bob shook his head.

“Not as far as I know, and I guess if there had been I wouldn’t be at liberty to tell you.”

Jacobs put on his coat.

“Coming down tonight?”

“I’ve some routine I can get out of the way,” replied Bob. “I’ll have lunch nearby and will be able to get through in a couple of hours.”

“I should come back, but I’m all in. Don’t work too late.”

The filing chief stepped out of the office and closed the door behind him and Bob was left alone in the long, high-ceilinged office. The room was in heavy shadows already, for the day had been cloudy and twilight had come early. He turned on the light over his desk, decided that he was hungry, snapped it off, put on his coat and left the office. At the door he turned and made sure that the room was securely locked. Then he walked rapidly down the corridor, turned, and signalled for an elevator.

Bob was walking through the main doors when someone hailed him and he saw his uncle.
