Type a Bluesky handle. Six of its mutuals become the suspects — one of them is the killer — a few more become rival detectives who hold cards, and the weapons and rooms are popular-but-unique trigrams.

✓/✗ deductions are filled in for you when they're certain (your own hand, cards shown to you, and anyone who fails to disprove). Add your own by clicking. A row turns gold when everyone's been ruled out — no one holds it, so it's in the envelope.
