1898 - Whitechapel, London
The night is covering its alleyways with a dark cloak, leaving only a few areas lit by the gaslights.
Eight investigators have come together to track down Mr Jack, still at large.
Mr Jack is very clever, though: he is pretending to be one of them...
Aim of the game
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.
