She was walking slowly across the hall towards Olivia's room, whither a bell had just summoned her. Mrs. Marchmont had lately grown fretful and capricious, and did not care to be waited upon by any one except this woman, who had known her from her childhood, and was no stranger to her darkest moods.

Edward Arundel had determined to appeal to every living creature who was likely to know anything of his wife's disappearance, and he snatched the first opportunity of questioning this woman.

"Stop, Mrs. Simmons," he said, moving away from the window; "I want to speak to you; I want to talk to you about my wife."

The woman turned to him with a blank face, whose expressionless stare might mean either genuine surprise or an obstinate determination not to understand anything that might be said to her.

"Your wife, Captain Arundel!" she said, in cold measured tones, but with an accent of astonishment.

"Yes; my wife. Mary Marchmont, my lawfully-wedded wife. Look here, woman," cried Edward Arundel; "if you cannot accept the word of a soldier, and an honourable man, you can perhaps believe the evidence of your eyes."

He took a morocco memorandum-book from his breast-pocket. It was full of letters, cards, bank-notes, and miscellaneous scraps of paper carelessly stuffed into it, and amongst them Captain Arundel found the certificate of his marriage, which he had put away at random upon his wedding morning, and which had lain unheeded in his pocket-book ever since.

"Look here," he cried, spreading the document before the waiting-woman's eyes, and pointing, with a shaking hand, to the lines. "You believe that, I suppose?"

"O yes, sir," Barbara Simmons answered, after deliberately reading the certificate. "I have no reason to disbelieve it; no wish to disbelieve it."

"No; I suppose not," muttered Edward Arundel, "unless you too are leagued with Paul Marchmont."
