The Back Door
Mr. Wall is the manager of a big bank. Last Thursday
afternoon,。Mr. Nelson came to Mr. Wall's office in the bank and
talked to him for a long time. Then Mr. Wall looked at his watch
and said, "Look at the timel The bank closed a quarter of an hour
agol They've locked all the doors now, and there are three of them
between us and the street. But 1 have keys, because 1 sornetimes
work late here after everyone else." He took some keys out of his
Pocket.
Mr. Wall and his visitor went out of his ofice, and then they
saw Mrs. Field. She cleaned the bank every evening after 5:30.
"Go out through the back door," she said to the manager. "They
never lock that one." R
