"I have not written for a long time. I shall send my next to her man of business."

"And won't I just give Mona a vivid account of how I came to do it!" she added mentally.

"Have you seen this lady—Mona's cousin? I don't know anything about her."

"No, I have not. I believe she is very quiet, and elderly, and respectable,—and dull; the sort of person in whose house one can get through a lot of work."

"Humph," growled Sir Douglas. "A nice life for a girl like Mona!"

"I am sure I wish she were here!"

Sir Douglas looked at her. "Some of us," he said quietly, "wish that every day of our lives. I called the other day to take her for a drive in the Park, but found she had left her old rooms." And then he told the story of his little misadventure of a few days before.

"Oh," said Lucy, "what a terrible pity! Mona loves driving in the Park. Do go for her again some day when she is working in London. You have no idea what a treat a drive in the Park is to people who have been poring over their bones, and their books, and their test-tubes."

"Well, what in the name of all that is incomprehensible does she do it for? She might drive in the Park every day if she chose."

"But then," said Lucy, "she would not be Mona."
