Murder Mystery Advent Calendar: A Clue a Day Until Christmas

A murder mystery advent calendar gives you one new clue every day from 1 to 24 December. How it works, who it suits, how to turn it into a gift, and a printable one to try.

Twenty-four advent doors, each hiding a clue to a Christmas murder mystery

An ordinary advent calendar gives you a chocolate a day. A murder mystery advent calendar gives you a clue a day: open a door each morning in December, read a few lines of the story, rule out a few more suspects — and on Christmas Eve, only the killer is left.

It has become one of the most-searched Christmas gift ideas for puzzle lovers, and for good reason. Here's how they work and how to get the most out of one.

How a murder mystery advent calendar works

Before December starts you get the case: a crime, a set of suspects or records, and the question you have to answer. Then, from 1 December:

  1. Open one door a day. Each door holds a short piece of story and one new clue.
  2. Apply the clue. Cross out everyone and everything the clue rules out.
  3. Check your count. Good calendars tell you how many suspects you should have left, so a slip on day 6 doesn't ruin day 20.
  4. On 24 December only one answer remains. Name it — and open the sealed solution on Christmas Day.

Opening a door: a little story and one new clue

The daily sessions are short — ten or twenty minutes over breakfast — which is exactly what makes it a ritual rather than a chore.

Who it's for

If you'd rather not wait, most calendars can also be binged in a weekend — any time of year.

Physical or printable?

Boxed murder mystery advent calendars look beautiful and cost accordingly. A printable one has three advantages:

The Parcel Post Poisoner, a Christmas 1952 advent calendar mystery

The Parcel Post Poisoner is set in a Vermont post office at Christmas 1952. A man has been poisoned, an innocent woman has been arrested, and the killer has hidden the evidence in the one place nobody may search: the Christmas mail. Three hundred hand-drawn parcels sit on the snowbound shelves until the mail train leaves on Christmas Eve — and the judge will sign a warrant for just one of them.

How to give one as a present

  1. Print the door cards on card stock and fold them as the instructions show.
  2. Number a small box or a ribbon line from 1 to 24 and clip the doors on.
  3. Seal the solution in an envelope marked "Do not open until Christmas Day".
  4. Add the case file and a pencil — and, if you're feeling generous, a box of chocolates for door 24.
