Straight ahead you'll see a row of clocks on the mantelpiece, with a switch underneath and a keyhole on the right. Clearly a puzzle, but you'll need both the key and some idea about what time you want before even starting on this one.
At the left, go forward to look at Charlotte's dresser. Here you'll find a sort of journal and a jewelry box.
Hint 5
The journal only has two readable pages. The text is ominous but confusing, since it doesn't name any names. The diagram on the right says it has to do with Franklin's memorial. You might want to take a picture of it with Nancy's phone -- odds are you'll need it eventually.
