With illustrations from the original novels; this card game goes some way to evoke the feeling of the chase through Victorian London to unmask Moriarty and other villains. Players draw and lay cards in sequence; Movement; Location; Info; Action; Detectives and Villains. So I might take a train to the Country; find a clue and use a Disguise. I can use an Inspector; Arrest or Alibi card on my opponents and so on. Play ends either when an Arrest successfully reveals a Villain; or when a player discards their last card; a Villain; who Escapes. Scoring is based on cards remaining in your hand; and if you are the arresting or guilty player; caught with a Villain in your hand.
