“I am not sure that it is idle curiosity,” Drake said reflectively. “She is very fond of her sister, and——”

“We will change the subject,” Gaunt said peremptorily, and Drake realized that it would be dangerous to persist further.

However, Gaunt was fated to meet with a more strenuous advocate, for Lady Ethel herself came into the library.

“Mr. Drake, I wish to speak to Mr. Gaunt,” she announced quietly, and then smiled a little maliciously as he prepared to depart.

“What do you want? I’m busy and haven’t much time to spare,” Gaunt said curtly, for he did not approve of the way in which she had spoken.

“Busy with the wretched Congo, I suppose? At any rate, you can find time to discuss a matter which affects the happiness of my sister,” she said slowly. “Unless, of course, the wretched natives are of more consequence than your wife,” she added quickly, and there was a look of defiance on her face.

“Don’t you think you would be wiser to concern yourself with your own affairs? It would seem probable that they will require attention, if you go on flirting in the same reckless manner,” he said significantly.

She flushed hotly and with difficulty suppressed an angry reply.

“I am not to be bluffed in that way. I have come for a serious talk and don’t intend to go away until we come to an understanding,” she said with quiet determination.

“Very well. Say your say and pray get it over as quickly as possible,” he rejoined with a sigh of resignation.
