24 DAYS. ONE INVESTIGATION.

Murder mystery Advent calendar books for adults.

A Christmas countdown can give you more than something to open. These two mystery puzzle books offer 24 days or nights of clues to work through, with different settings for different readers.

Choose your Christmas 2026 countdown.

A mystery Advent calendar book uses daily chapters or cases to move an investigation toward its solution. It is a printed book, rather than a box containing chocolates, toys or separate envelopes. You read the evidence and work out what it means.

Our two published countdowns combine floor-plan deduction with an ongoing whodunit. Place the people using the printed rules, identify the witness, and use the testimony to narrow the suspect list. The illustrated characters help you keep the investigation organized.

Questions before you choose

Can I start a murder mystery Advent book after December 1?

Yes. The countdown suggests a daily reading ritual; you can start later and work through the book at your own pace.

Are these escape-room boxes?

No. Merriweather’s and Ravenhurst are printed mystery puzzle books. The daily evidence and puzzles are on the pages.

Are the two books the same story?

No. Merriweather’s takes place in a department store and Ravenhurst in a film studio. Choose according to the reader’s preferred atmosphere.

Do both Advent books have an online QR hint companion?

The free online casebook belongs to the coming-soon Bellwick adventure. Do not assume it is included with Merriweather’s or Ravenhurst.
