"But there may be differences of opinion about what is right."

"If a man had a gangrenous foot would you have patience with anyone who hesitated to amputate it?"

What Davidson had done soon appeared. The four of them had just finished their midday meal, and they had not yet separated for the siesta which the heat imposed on the ladies and on the doctor. Davidson had little patience with the slothful habit. The door was suddenly flung open and Miss Thompson came in. She looked round the room and then went up to Davidson.

"You low-down skunk, what have you been saying about me to the governor?"

She was spluttering with rage. There was a moment's pause. Then the missionary drew forward a chair.

"Won't you be seated, Miss Thompson? I've been hoping to have another talk with you."

"You poor low-life bastard."

She burst into a torrent of insult, foul and insolent. Davidson kept his grave eyes on her.
