“Oh,” said Croft, looking around at her very coldly and sternly, “I begin to see.  I suppose a separation would improve your prospects in life.  But it can’t be done if your husband is opposed to it.”

“Mr Croft,” said the lady, her face flushing a good deal, “you have no right to speak to me in that way, and attribute such motives to me.  No matter whom I had married, I would never give him up for the sake of money, or a farm, or anything you think my aunt could give me.”

“I beg your pardon,” said Croft, “if I made a mistake, but I don’t see what else I could infer from your remarks.”

“My remarks,” said she, “were,—­well, they have a different meaning from what you supposed.”  She walked on in silence for a few moments, and then, looking up to her companion, she said:  “I have a great mind to tell you something, if you will promise, at least for the present, not to breathe it to a living soul.”

Instantly the lookout on the bow of Lawrence Croft’s life action called out:  “Breakers ahead!” and almost instantly its engine was stopped, and every faculty of its commander was on the alert.  “I do not know,” he said, “that I am entitled to your confidence.  Would it be of any advantage to you to tell me what you propose?”

As she made this remark the lady looked up at her companion with a smile and an expression of curiosity as to how he would take the announcement.  Lawrence gazed blankly at her for a moment, and then he broke into a laugh.  “You don’t mean to say,” he exclaimed, “that Mr Null is an imaginary being?”

“Entirely so,” she replied.  “My dear Freddy is nothing but a fanciful idea, with no attribute whatever except the name.”

“You are a most extraordinary young person,” said Lawrence; “almost as extraordinary as your aunt.  What in the world made you think of doing such a thing? and why do you wish to keep up the delusion among your relatives, even so far as to drive your aunt to the point of getting you divorced from your airy husband?” And he laughed again.  “I told you how I came to think of it,” she said, as they walked on again.  “It was very plain that if I wanted to travel about as your agent I must be married, and I have found a husband quite a protection
