Reginald Sixpence totters around the Chapel, searching for something hidden in the Marquis's safe. A few rooms over, one of the manor's servants shuffles around, an act that would be innocent enough if not for the hideous gas masks he wears, or for the simple fact that in a few hours he's going to pick up the antique hunting rifle and murder Sixpence. You know this because you, Lafcadio Boone, have seen it all before, and the task set before you in The Sexy Brutale is to now figure out a way to stop it.
Maybe you've come across this Groundhog Day-like gambit before in a video game (see Majora's Mask and Ghost Trick), but the eerie intimacy of The Sexy Brutale's mansion and the game's rapid pace—a 12-hour in-game time loop that passes in 10 minutes—makes the conceit feel fresh. Each discrete area of the two-story manor has its own decor and atmosphere, from a set of security cameras in the casino to a live rehearsal in the music room. And the scenarios of each are equally unique: Willow Blue, who haunts the long hallways of the guest rooms is driven by some unseen force to commit suicide, whereas two thieves find that they're the evening's entertainment after they become trapped in an on-stage deathtrap.
