Whitehall Mystery is a game of deduction and investigation that will allow you to walk the alleys of a late 19th century London in the evocative setting linked to Jack the Ripper. An emulator of his seems to have appeared in Whitehall, scattering the pieces of his poor victims around the streets. One of the players will take on the role of a serial killer ready to commit a series of heinous crimes, while the rest of the players, in the role of a group of investigators, will have to unmask and catch him before it's too late ... in a frantic hunt for 'man ... The terrible crimes take place in Whitehall, which is represented on the game board divided into 4 quadrants and organized according to an intertwining of streets, intersections and a series of numbered boxes that can be in white background - the streets - a black background, to indicate crowded alleys or patrolled by the police, or blue background, that is the docks. Only the white boxes can be used by the assassin as a place of discovery, however some special abilities, from both sides, will allow you to move between places on the same block (all areas limited by a polygon of roads) without necessarily following the connections of the streets.
