Christmas Mystery Dinner Party Builder

Host a Christmas whodunit for 6 to 12 guests from one offline web page. Codex writes an original, fair mystery, checks it with its own consistency checker, then builds the evening: private character packets with codes, three acts on the TV with clue reveals, a secret ballot, the solution walkthrough and awards, and printable invitations, booklets, clue cards and a host script in three styles.
