Lie if you must

Earlier, Susan had temporarily put a halt on her "investigation." She had thought about it and felt there was no need to think wildly and suspect Damian had a hand in everything and was making Tyra lie for him.

She thought thinking so was silly, and now that they had raised the topic of finding out what happened to Sir Wilson, they were already a step closer to finding the real culprit.

But Susan had a curious spirit. And after someone had secretly given her a note telling her to find Katherine, she could not just sit back. So even though she was no longer suspicious of Damian, she still wanted to know who Katherine was, and this time, she decided to ask two people who were closer to her than other maids. 

Susan had found Paulina in the painting room, and when she entered, Paulina looked very tense and jumped from where she had been sitting, painting.
