Historical Mystery: Death at the Ball

From BoardGameGeek:

Death at the Ball is the first game in the detective series “Historical Mystery”. The French court is in distress - all of a sudden an established nobleman passes away for no apparent reason but… poisoning. You are on this controversial case, accompanied by other investigators. Try and solve the case in 24 moves: visit wealthy households, interrogate aristocrats and commoners who knew the victim and hunt down every detail. Choose the cards to investigate together. At the end of the game, you will be asked a series of questions and if you answer correctly - you win. Players prepare 15 decks without shuffling or flipping cards. Starting from the first card they begin to follow the instructions. As they read through the story, they will encounter icons with numbers of decks: new places and people they unlock. Players will have 24 Moves: chances to flip one of the available cards. They will either examine places or objects, or interrogate suspects. During the game it is important to pay close attention to the details and people's expressions in the pictures – it will help you solve the crime! When players are out of the Moves, they need to scan the “Question” QR-Code and give answers to a series of questions concerning the case. Then they can check right answers and the whole story description.
