From the publisher's website:

In the 1920’s, Mr. MacDowell, a gifted astrologist, entered in his new house when he immediately detected a surnatural being. Gathering eminent mediums of his time for an extraordinary seance, they will have 7 hours to contact the ghost and investigate to unlock an old mystery… Unable to talk, the amnesic ghost will communicate with the mediums through visions (illustrated cards). They will have to decipher the images to help the ghost remember how he was murdered (who? where? which weapon?). The more they cooperate and guess well, the easier it will be to the catch the right culprit. This party game is one of the most anticipated games of 2015, thanks to innovative, thrilling and immersive features. It offers cooperation and investigation with an asymmetrical gameplay. While playing the ghost or a medium, you will have fun trying to guess what other players have in their minds! So enter in this strange manor and let yourself be led by your intuition!
