thank you so much! now i've finally gotten everything from chapter 1, you wouldn't happen to know the last secret in chapter 2? i've only got that one and number 25 left
I forget which one of the secret pictures is where, so I'll just list both: one is found in the hidden object room at Lady Carhen's house. I believe it's the center candle flame you'll want to click on. The other is found by clicking on the shield in the coat-of-arms on the Stonehold map.
#25 is found by talking to the spymaster after you attend the ball. Just keep clicking the options to talk about how Lady Ballymore liked you.
