Double Trouble - Suspicion

About Suspicion, from BoardGameGeek:

You are a jewel thief, and you've been invited to the mansion of someone who doesn't know that you engage in such nefarious doings. While at that mansion, you're going to try to nick as many jewels as possible, but *gadzooks* the mansion turns out to be filled with jewel thieves who are all trying to do the same thing. Can you out them publicly, while staying unknown yourself and bagging a nice collection of gems? In Suspicion, ten characters start on the perimeter of the game board, and each player is secretly one of these characters. On a turn, you roll two dice, then move the two characters shown (or characters of your choice if you roll a joker). After this, you play one of the two action cards in your hand, and carry out one of the actions on that card: stealing a type of gem in the space where your character is located, moving any character, asking someone else whether their character can be seen by someone on the board, and so on. Gems come in three types, and when one of the piles is empty, the game ends. Everyone guesses who is which character, then all identities are revealed. For each player you've guessed correctly, you score 7 points; for each set of three different gems, you score 6 points; and for each individual gem aside from the sets, you score 1 point. Whoever has the most points wins!
