The Advent Case Files is a December puzzle book from Clue Craft that pairs 24 short murder-mystery stories with Sudoku-style logic grids. Each day from December 1 to 24 you read a case, place nine people on a 9×9 grid using the clues, and name the killer. Cases get harder as the month goes on, and every one has a single logical solution with a full written deduction. It suits puzzle fans who want a daily ritual rather than a one-sitting read, and it stands out from ordinary advent calendars by giving you a solvable mystery each day instead of a trinket.

The Advent Case Files is an Advent calendar book for adults that combines detective stories with Sudoku-style logic puzzles. It has 24 fictional murder cases, one for each day from 1 to 24 December. Settings include a candle workshop, a mountain rescue station, a historical printing works, a cathedral and a steamship.
Each case has a short story and an illustrated crime scene on a 9×9 grid. Nine people, including the victim, must be placed on the grid using clues to their positions. Every case has a unique logical solution, and the placements lead to the identity of the murderer. The cases grow more demanding as you progress through the book.
Every case has two levels of hints, so you can choose how much help to use. Complete solutions show everyone's positions, the culprit and an explanation of the deduction. Full instructions explain the format before the first case. You can follow the daily countdown or solve the cases at your own pace.
