“No, about flesh and blood, which you prefer. Sir Frank Random has arrived back at the Fort. There!”

“I know that,” was Miss Kendal's unexpected reply. “His yacht came to Pierside on the same afternoon as The Diver arrived.”

“Oh, indeed!” said the Professor, struck by the coincidence, and with a stare. “How do you know?”

“Archie met Sir Frank the other day, and learned as much.”

“What?” Braddock struck a tragic attitude. “Do you mean to say that those two young men speak to one another?”

“Yes. Why not? They are friends.”

“Oh!” Braddock became roguish again. “I fancied they were lovers of a certain young lady who is in this room.”

By this time Lucy was beginning to guess what her step-father was aiming at, and grew correspondingly angry.

“Archie is my sole lover now,” she remarked stiffly. “Sir Frank knows that we are engaged and is quite ready to be the friend of us both.”

“And he calls that love. Idiot!” cried the Professor, much disgusted. “But I would point out to you, Lucy—and I do so because of my deep affection for you, dear child—that Sir Frank is wealthy.”
