In the 1920s, Mr. MacDowell, a gifted astrologer, immediately detected a supernatural being upon entering his new house in Scotland. He gathered eminent mediums of his time for an extraordinary séance, and they have seven hours to make contact with the ghost and investigate any clues that it can provide to unlock an old mystery.

Unable to talk, the amnesiac ghost communicates with the mediums through visions, which are represented in the game by illustrated cards. The mediums must decipher the images to help the ghost remember how he was murdered: Who did the crime? Where did it take place? Which weapon caused the death? The more the mediums cooperate and guess well, the easier it is to catch the right culprit.

In Mysterium, a reworking of the game system present in Tajemnicze Domostwo, one player takes the role of ghost while everyone else represents a medium. To solve the crime, the ghost must first recall (with the aid of the mediums) all of the suspects, locations, and murder weapons present on the night of the murder.

If one or more mediums fail to identify their proper suspect, location and weapon before the end of the seventh round, then the ghost has failed and dissipates, leaving the mystery unsolved. If, however, they have all succeeded, then the ghost has recovered enough of its memory to identify the culprit.

If a majority of the mediums can identify the proper suspect, then the killer is identified and the ghost can now rest peacefully. If not, well, perhaps you can try again...
