Mr. Jack in New York

As part of the investigation into the "Jack the Ripper" affair, Francis J. Tumblety, a quack doctor, is arrested and released on bail. He immediately flees to the United States. Alerted by London, the New York police are on the lookout for Tumblety. Various witnesses confirm his presence in Manhattan and crimes are committed with a modus operandi similar to those in London. The police call upon some of the city's most eminent citizens to help them with their investigation. Is Tumblety really Jack? If not, who is he pretending to be? These are the stakes in "Mr. Jack in New York"

Eight investigators have gathered to catch the cunning Jack. But Jack is in fact cleverly impersonating one of them. By moving each character into light or shadow, the detective player makes successive deductions to uncover which investigator is in fact Jack, then he/she must try to catch the infamous Jack. The opponent, playing Jack, must do his best to delay the investigation. He can even try to use the darkness to secretly flee the district! 

The goal of the player who plays Jack is to escape the investigator before dawn or to leave the district by taking advantage of the darkness. For the player who is "the detective", his goal is to uncover which investigator Jack is impersonating and to catch him before dawn.
