A frowsy little servant opened the door.

“Is Dr Twiddel at home?” he asked.

“Dr Twiddel’s abroad, sir,” said the maid.

“No one in at all, then?”

“Dr Billson sees ’is patients, sir—w’en there his any.”

“When do you expect Dr Billson?”

“In about an hour, sir, ’e usually comes hin.”

“Excellent!” thought Mr Bunker. Aloud he said, “Well, I’m a patient. I’ll come in and wait.”

He stepped in, and the door banged behind him.
