Note: potential spoiler for An Eye for an Eye in this post.
thanks for emailing me a copy of your clue cards steve. they are very well done.
in practice did you not find some of them to be too overt? the hidden places clues in particular.
i'm trying to visualise how you use them... the players enter the library and you hand them a card titled 'hidden places' drawing attention to the carpet - wouldn't this simply result in them flipping the carpet?
or do you hold back the card until they discover the secret beneath it.
