After discovering the game and the 5 first cases as a detective or as the Chisel in "Enquêtes à Los Angeles" (the French version of Detective: City of Angels), you can know continue the experience with the 4 next cases. WARNING: You will need the core game to play with "Nouveaux Crimes" as the box will only contain the 4 new cases and the corresponding booklets. Even if the different cases will be slightly harder one after the other, the game stays the same: a 3 to 9 players asymmetrical investigation game. The detectives will have to solve the case before their opponents. The Chisel will try to manage the story and how it's told, sometimes helping a detective in distress, sometimes slowing a lucky detective down, choosing the answers of the interrogated witnesses. Every game, dive deep into the nice film noir atmosphere of Los Angeles during the 40s. -description from publisher
