When you think you’ve figured out which three cards are in the envelope, you may, on your turn, make an Accusation.  First say “I accuse (Suspect) of committing the crime in the (Room) with the (Weapon)”  Then, so that the other players do not see, look at the three cards in the envelope.

In a Suggestion, the Room you name must be the Room where your token is located.  But in an Accusation, you may name any Room.

Winning the game:
If the Accusation is completely correct, that is, if you find in the envelope, all 3 cards that you just named, lay the cards face up on the table and you are the winner.
