“No, sir,” he declared, “I am ashamed to say that I am not very clear as to the actual expressions I made, but Mrs. Watson has assured me that my behaviour to you was discourteous in the extreme.”

“I hope you will think no more of it. I had already,” Mr. Sabin said, “forgotten the circumstance. It is not of the slightest consequence.”

“You are very good,” Mr. Watson said softly.

“I had the pleasure,” Mr. Sabin remarked, “of an interesting conversation with your wife last night. You are a very fortunate man.”

“I think so indeed, sir,” Mr. Watson replied modestly.

“American women,” Mr. Sabin continued, looking meditatively out to sea, “are very fascinating.”

“I have always found them so,” Mr. Watson agreed.

“Mrs. Watson,” Mr. Sabin said, “told me so much that was interesting about your wonderful country that I am looking forward to my visit more than ever.”

Mr. Watson darted a keen glance at his companion. He was suddenly on his guard. For the first time he realised something of the resources of this man with whom he had to deal.
