Quote #7
Nothing that he had said or did shook my opinion of the disgraceful series of falsehoods that he had told, in my presence, the day before, or of the cruel deception by which he had separated Lady Glyde from her sister. (2.3.2.149)
Mrs. Michelson comes down pretty harshly on the side of truth here, as her diction reveals. She never forgives Sir Percival for the lies he told and the way he treated Marian and Laura.
Quote #8
Her mind in this instance […] confusedly presented to her something which she had only intended to do in the false light of something which she had really done. This unconscious contradiction of herself was easy to account for in this way—but it was likely to lead to serious results. (3.1.3.20)
The unreliability of memory is a running theme throughout the book. Here Laura becomes a sort of unintentional liar, thanks to her Swiss cheese memory, which confuses fact and fiction.
Quote #9
It was hard sometimes to maintain our innocent deception, when she proudly brought out her purse to contribute her share towards the expenses, and wondered, with serious interest, whether I or she had earned the most that week. (3.1.8.13)
Contrast Walter's description of his "innocent deception" of Laura, with Sir Percival's (featured above), which is terse, abrupt, and defensive in tone. In case we weren't all on the same page, Walter is cool, Sir Percival is a punk.
