and wander about it sadly. She said her mother had got some secret of Sir Percival’s to keep, and had let it out to her long after I left Hampshire—and when Sir Percival found she knew it, he shut her up. But she never could say what it was when I asked her. All she could tell me was, that her mother might be the ruin and destruction of Sir Percival if she chose. Mrs. Catherick may have let out just as much as that, and no more. I’m next to certain I should have heard the whole truth from Anne, if she had really known it as she pretended to do, and as she very likely fancied she did, poor soul.”
This idea had more than once occurred to my own mind. I had already told Marian that I doubted whether Laura was really on the point of making any important discovery when she and Anne Catherick were disturbed by Count Fosco at the boathouse. It was perfectly in character with Anne’s mental affliction that she should assume an absolute knowledge of the secret on no better grounds than vague suspicion, derived from hints which her mother had incautiously let drop in her presence. Sir Percival’s guilty distrust would, in that case, infallibly inspire him with the false idea that Anne knew all from her mother, just as it had afterwards fixed in his mind the equally false suspicion that his wife knew all from Anne.
