"You are absurd. You pretend that you see nothing, whereas I am sure you see more than I, but you refuse to speak."

Royson seemed to be singularly unaffected by this outburst. He caught the angry flush on the girl's forehead, and, as was his way when the stubborn fit seized him, threw his head back, with lips set. Irene stole a look at him, and laughed constrainedly.

"Very well. If you won't talk I must," she said with a great air of determination. "It is about Mrs. Haxton."

"A most interesting topic," said Royson.

"That is what my grandfather seems to think."

"He told me last night that he considers her a singularly well-informed woman."

"For well-informed read artful," exclaimed the girl bitterly. "Have you forgotten what I said to you in the canal? When we began our voyage Mrs. Haxton and the Baron were as good as engaged. Now they have reached some agreement which permits Mrs. Haxton to fly for higher matrimonial game than a penniless adventurer."

"Do you really think that?"

Royson had grown suddenly serious. He half turned in the saddle so as to seek the added inspiration of Irene's expression, but she kept her eyes studiously averted, and the broad-brimmed pith hat she wore helped to conceal her face. But she answered readily.

"I am quite certain of it. How else could I discuss it with you?"
