"13 Indices" french card game

London, 1899, the city is shaken by odious crimes whose culprits remain untraceable. Scotland Yard is in a fog and has summoned the city's best detectives, including you, to solve the unsolved cases. Each investigator will have to use his or her instincts to discover the identity of the murderer and the location and weapon of the case they have been assigned. Everyone works on their own case but only has access to the clues of their opponents (characters, places and weapons). By asking questions and consulting with undercover agents, one must gather clues that will help one's own investigation, or else the clues will be useful to others! The goal: to be the first to solve your investigation.
