Question assumptions, weigh different possibilities and decide what actually makes sense.
Piece together scattered information and work your way toward a logical solution.
Case #000 is a short but complete investigation designed to show you exactly what solving inside The Case Vault feels like.
Not the same worksheet with a different title. An auction murder looks like an auction catalogue. A secret society feels classified. A garden-party killing unfolds through maps, schedules and witness cards.

A good mystery should make you feel clever when you solve it—not lucky.
