“This isn’t your lucky day, George,” said Kirk. “Well, I guess I’ll phone to the doctor.”

“Quite unnecessary.”

“I beg your pardon?”

“Entirely unnecessary. I have made an examination. There is practically nothing the matter with the man. Put him to bed, and let him sponge his knee with warm water.”

“Are you a doctor, Mrs. Porter?”

“I have studied first aid.”

“Well, I think, if you don’t mind, I should like to have your opinion confirmed.”

This was rank mutiny. Mrs. Porter stared haughtily at Kirk. He met her gaze with determination.

“As you please,” she snapped.

“Thank you,” said Kirk. “I don’t want to take any risks with George. I couldn’t afford to lose him. There aren’t any more like him: they’ve mislaid the pattern.”
