M. Sydney has been shot in the head and killed. As the head of a crime investigation team of the Gendarmerie, you're called on the scene to collect evidence and interrogate witnesses. You'll lead the investigation, look for suspects, work with the different services of the gendarmerie, use the police computer network DIAMANT, and build your case. Only with enough evidence can you hope to have the suspect you choose convicted by a jury.
L'Affaire Sydney is a graphical adventure, and the sequel to "L'affaire Vera Cruz".
