Margaret Walsingham had answered Mrs. Brand's advertisement for a companion four years previously, when she was a pale, timid girl of twenty, clad in orphan's weeds, and scarce lifting her deep, earnest eyes to the inquisitive gaze of her patroness; but her quiet, grave, soulful character had strangely fascinated the haughty old lady, and from the humble post which she had gone to Castle Brand to fill, she quickly rose to be the prime object of all its mistress' dreams, to be beloved, and indulged, and admired as no living mortal had ever been by that closely-guarded heart, save St. Udo Brand. Margaret Walsingham was a sea-captain's daughter. Up to her twelfth year she had sailed the seas in his ship and looked to him for society; and not till then was she sent on shore to be educated. Still the stout captain had been ambitious for his daughter, and had taken care that her education, when it did commence, should be thorough, comprehensive and elegant in all its branches; so that when after eight years of ceaseless learning on her part, and ceaseless voyaging on his, he proposed going home to England and retiring with his daughter upon a handsome fortune, she was well fitted to adorn the society he intended to surround her with. But the ill-starred captain went down in a Biscay gale when also within sight of home, and with him went his whole life's savings, leaving his Margaret fatherless, homeless and fortuneless. And that was why she answered Mrs. Brand's advertisement. St. Udo Brand was an officer in the Coldstream Guards, now in London. He was the only son of Mrs. Brand's only son, Colonel Cathcart Brand, long dead. Cathcart Brand had been a sad rake, lawless, reckless, and a natural spendthrift. The one act of worldly wisdom which he had ever achieved was his marriage, late in life, with a lady of noble birth, whose ambitious leanings and insatiable vanity had scourged the easy colonel up into the highest social circles, and in some measure covered his _blasé_ reputation with her gilded arms.
