[FitD] Handling puzzles in Forged in the Dark - games

Hey!

What the title says.

In general, would love to hear how GM's have handled puzzles in the rulesets of Forged in the Dark games. I have an upcoming game where tha players go to a masquerade in search of a specific guest, only to be surprised by finding as a "backup" five people donning the exact same mask. Constructing this game session around the Forged in the Dark ruleset - how should I handle it? Make a clock that the players proceed to fill out to figure out which of the guests is the real one? How should I drive that narratively?

The game setting in specific is Court of Blades, but I don't think that matters too much since it's so close to Blades in theme.
