Who is The Murderer is a Chinese TV Show about 6 people + 1 detective trying to find the murderer among the 6 players. Each episode has different cases to solve, and sometimes different casts as well. It's also quite funny. The first two and last two episodes are usually the best because they are filmed in the actual location and not in the studio. I suggest you watch it if you like detective TV shows like Busted. It might not be as good as Busted but it's still a good show.
