“No,” said Sir Nathaniel, “I don’t know that I ever did. Why, may I ask?”

“That was the look. Certainly not amatory or anything of that kind—yet it was, it struck me, more dangerous, if not so deadly as an actual threatening.”

Again there was a silence, which Sir Nathaniel broke as he stood up:

“I think it would be well if we all thought over this by ourselves. Then we can renew the subject.”

CHAPTER VII—OOLANGA

Mr. Salton had an appointment for six o’clock at Liverpool. When he had driven off, Sir Nathaniel took Adam by the arm.

“May I come with you for a while to your study? I want to speak to you privately without your uncle knowing about it, or even what the subject is. You don’t mind, do you? It is not idle curiosity. No, no. It is on the subject to which we are all committed.”

“Is it necessary to keep my uncle in the dark about it? He might be offended.”

“It is not necessary; but it is advisable. It is for his sake that I asked. My friend is an old man, and it might concern him unduly—even alarm him. I promise you there shall be nothing that could cause him anxiety in our silence, or at which he could take umbrage.”

“Go on, sir!” said Adam simply.
