Detective Dee and the Mystery of the Phantom Flame (2010)

Apparently impossible deaths threaten the preparations for an imperial coronation, bringing a distrusted investigator back into a dangerous court. Tsui Hark lets physical clues, political motives and extravagant action occupy the same case. Try it if you want the pleasure of competing suspects on a much more fantastical scale. This is a genuine culprit mystery, but wire-assisted combat and spectacular design take as much space as quiet deduction.
