The Secret of Dr. Kildare 

HOURS later, and every hour like the weighty length of a day, Kildare was saying: ‘Next, please!’ when Mary Lamont answered: ‘That’s the end of the line for today.’
He shook his head at her impatiently. ‘There are twenty more people out there!’ he declared.
‘I’ve sent them away, ‘ she said.
‘You sent them away?’ exclaimed Kildare.
‘I had orders from Doctor Gillespie.’
‘But a Gillespie day never stops-it’s from noon to noon, ‘ protested Kildare.
‘He won’t let you keep those hours, ‘ said the girl. ‘He gave me express orders that the line is not to keep pressing in at you day and night.’
Kildare dropped into a chair, unbuttoned his white jacket at the throat, and wiped away perspiration from around his eyes. Hospitals are always too hot. He merely said: ‘I suppose he’s right. He’s always right. I’d be a fool to try to imitate him. He goes in seven-league boots, and I’m only a measuring worm…I suppose he wants me in the laboratory.’
