Yay! I knew quite a lot of them, which I haven't for most of the quizzes! However, I'll choose the two I'm most known for.
#55 is
Spoiler:The Lost Crown, in Harbor Cottage.
#38 is
Spoiler:Dark Fall: The Journal, in the foyer. "I left it...in a silver teapot."
Spoiler:But I also knew 4, 7, 13, 14, 34, 48, 49, 56, 66, 75, 78
Glad to see you back, Trunkyo.
