Shadow House: Masquerade

From BoardGameGeek:

We were invited to a gracious aristocrat's mansion for a dinner party. Suddenly, a horrifying scream pierced through the gathering "Viscount Shadow is dead!!!" Despite the momentary chaos, the butler responded swiftly, securing all doors and windows. Now the culprit must be trapped, leaving every person in the house under suspicion... In this fast-paced card game, players must catch the culprit who is still hiding amidst. However, for the culprit, they must hide until the last turn to steal the precious gems. Alternatively, they can pass the culprit identity card to another player and then catch them later on! -description from the publisher
