Who's the Murderer Season 1 (2016)

Season 4 of the show, the detective now has an assistant (played by a university student) to help them solve the case.

Season 5, more cases, new and old faces help solve the cases. The season starts off on a (real) cruise ship and ends on a (real) train!

This season starts off in a grand hotel and later connects characters from previous seasons and settings.

The return of fan favourite "band" No Zuo No Die who always somehow get tangled up in a murder mystery.

Fan favourite "band" No Zuo No Die gets their own comeback concert with special guests MG Entertainment performers/trainees and the debut performance of MG's new girl group, YCYU

Both are mystery genre shows, players have to find hints from a confined space to solve/walkthrough the game.

Mystery. Death. Murder.

Both 'Who's the Murder' and 'The Truth' involve a series of random or interconnected cases in which one or more individuals are murdered. The main cast must investigate the scene, interview suspects and work together to not only solve the case but vote for the murderer. Only the murderer can lie, everyone else must tell the truth when asked. If the murderer is voted correctly then the rest of the cast earn themselves a golden key or small bar of gold. But if the murderer successfully manages to escape suspicion then he or she gets awarded with the prize.

In a game of cat and mouse, no one is who they seem.

Trust no one.

Both are investigation related shows with very similar production styles. The main cast is very similar between both shows. The major difference is that Who's the Keyman investigates non-murder incidences.

This is the Chinese counterpart to the Korean variety show "Crime Scene". In this show, participates have to find who is the murderer among them in a mock crime scene. Later seasons feature some episodes with real locations or completely built sets, which leads to more immersive environments like the "Great Escape".

Season 2 of Who's The Murderer, small changes to the concept, same basic setup and new cases to solve.

New season with bigger and more realistic sets (like a hotel in the first few episodes) and more complex cases to solve.
