They thought the secret of Warwick mansion had been solved and the spirit had found peace, but now new signs have emerged that were previously hidden. New suspects, places, and objects that do not fit into the picture - and the presence of the ghost is strong once again. 2 to 7 players Ages 10+ 42 minute playing time The haunted manor still holds a few secrets... A semblance normality returned to Warwick manor in the period following the Grand Séance last Samhain night. In recent months, however, the ghost has begun to manifest again, disturbing the peace. Its presence has become stronger, and the manor's owner and professional astrologist Conrad Mac Dowell iOS convinced that the ghost is seeking to relay another message. Could the psychics have been mistaken? Still unable to speak, the ghost intends to communicate new telepathic visions to the psychics. Might the presence of other suspects in the manor cast doubt over their findings regarding the circumstances of the ghost's death (who killed him, where and how?). The only way to offer the ghost peace is for the psychics to gather for another investigative séance. Mysterium, the asymmetric, cooperative mystery-solving game is back with its first expansion: Mysterium Hidden Signs. This expansion includes 6 new characters, 6 locations and 6 objects enabling multiple new game configurations. The ghost has 42 new vision cards with which to communicate. Step inside, be seated and let your sixth sense guide you! Return to the manor - your seat at the séance table awaits...
