Crazy Idea: Let's start up a group project!

Getting a bit off the topic, that last bit reminds me: I once had an idea where one player would be a detective trying to solve a murder mystery created by a bunch of other players, one of whom would be the murderer and the rest of the players would be suspects. The suspects and murderer would be conspiring together to make it interesting. But I didn't think it through very well.

A variant occurred to me a little while ago; same set up, multiple detectives, the detectives are competing to be the first to solve the mystery. And just now, it occurs to me that maybe some of the suspects could be secretly trying to help a specific detective win.
