"Mrs. Mark Cray. To confess to you my opinion, I think she might have lent me the carriage this morning, instead of sending me out in a hired fly, and keeping the carriage for herself and the girls. It seems to be the way of the world nowadays--the young before the old. She is Mark's wife, and I am only his mother."

Whether Sara would have found a suitable answer is uncertain. Something outside completely took away all thoughts of it. They were at that moment passing the War Office; and, coming from it with an angry and determined look upon her pretty face, was the person whom she had just heard called Catherine Wentworth. Sara shrunk back in the cab's corner, dismay on her countenance, dismay in her heart. Had she already denounced Captain Davenal at headquarters?

From milliners to linen-drapers, from linen-drapers to dressmakers, one place after another continually, until Sara was tired to death, the day wore away. The afternoon was getting on when the last commission was done, and Mrs. Cray, who had put on the new bonnet just bought, had leisure to think of the horse and driver.

"Poor things, they must want some repose," she remarked, as she came out of the Pantheon. "Well, there's only one place more. Will you tell the man, my dear?" she added as she got in. "Parliament Street. You know the number, I suppose."

"What number?" inquired Sara. "Where to in Parliament Street?"

"To Mr. Oswald Cray's. Bracknell and Street, I think, is the name of the firm."

"There!" returned Sara in her discomposure. "I can't go there."

"Not go there! My dear, I must go there. Mr. Oswald Cray is my step-son. I shall call in for a minute to let him know I am in London."

Opposition would be worse than acquiescence. Besides, what could be her plea? Sara, all her pulses fluttering, spoke the address to the driver, and took her place in silence opposite Mrs. Cray.
