A Christmas murder mystery without actors or roles: how to host one with friends

ARLing s. r. o. · 9 October 2026

Two kinds of murder mystery evening

In a role-play party game, each guest plays a character from a script. In a pencil and paper logic puzzle, one solver or a team works through the same case, and nobody plays a part. A group can solve it together at the table, or one person can play alone over several evenings. Nobody has to learn lines, and a guest who cannot come leaves no gap in the story. If your group would rather act out characters from a script, a role-play game suits them better, and our case is not the right pick.

Our Christmas case is the second kind. It is set on Christmas Eve, 1928, at the Mistletoe Ball: the toymaker who pays for the ball every year is found poisoned in the quiet Library of the Royal Alder Hotel while 5,000 guests in costume dance under the tree. It is a classic style mystery, with no blood and no violence on the page.

Try a small case at the table first

Before you plan a whole evening around this format, try a small case. Ours has 12 guests and 4 clues, written in the same kind of sentences as our full case. At a Christmas party, someone took the gold star from the top of the tree. Read each clue, strike out every guest it rules out, and count who is left.

This is a fictional example; the guests are identified by surname only.

1. Table is an even number.
2. Drink is Cocoa or Eggnog.
3. Surname starts with a letter from A to M.
4. Costume and Surname start with the same letter.

Answer. You should have 7 guests left after clue 1, 4 after clue 2, 2 after clue 3 and 1 after clue 4. The star was taken by Caldwell, the Caroler at table 6 with an eggnog. Every clue matters: leave out any one of them and two or three guests are still in play.

How to build your own small case

1. Write the register first. List your guests with three or four columns, such as a costume, a table and a drink, and sort them by surname like a phone book.
2. Pick the culprit, then write the clues. Every clue has to be true for the culprit. Mix the kinds: a number (an even table), a short list (two drinks), a range of letters (surnames from A to M) and a link between two columns (costume and surname start with the same letter).
3. Count after every clue. Each clue should strike out at least one guest who is still in play. Our full cases go further: every clue removes at least 5 percent of the guests still in play.
4. Check that exactly one guest is left, and that every clue matters. Leave each clue out in turn. If the culprit is still the only guest left without it, that clue is not needed.
5. Keep it friendly. Make the culprit someone who is not at the table. That is the rule in our cases: the killer is always a stranger, so nobody you name gets accused.

A small case is easy to check by hand. A large one is not: our full case has 5,000 guests and 14 to 18 clues, and before it is released a second, separate program reads the printed clues and the printed register and checks that exactly one guest fits all the clues, that every clue removes at least 5 percent of the guests still in play and that every checkpoint number is right.

Running the evening with friends

• Share the register. Split the register pages between friends. Everyone strikes out guests on their own pages, and at each checkpoint you add up your counts.
• Use the checkpoints. Our case has 3 of them. In the full sample case on our shop page, the count falls from 5,000 guests at the start to 474 after clue 4, 47 after clue 8, 5 after clue 12 and 1 after clue 15. If your count is different at a checkpoint, go over the last four clues again before you go on.
• Paper or tablet. You need a printer and a pencil, or a tablet with a PDF app. The E-ink file has an index page and a row of letters on every register page that jump to that letter.
• Copies. You may print as many copies as you need for yourself, your family or your friends; please do not share or resell the files.
• Time. It is a long puzzle, so a group may need more than one sitting. You can also play alone over several evenings, for example between Christmas and New Year.

Our Christmas case, and who it is not for

Our personalized Christmas murder mystery is sold on Etsy for 14.90 €; in the EU, Etsy adds local VAT and shows the final total before you pay. One order holds two cases: Case No. 1, Murder at the Mistletoe Ball, is an instant download, and your own case with 3 to 14 friends as witnesses is ready a few minutes after payment. Each case comes as three PDF files: A4 with 88 pages, US Letter with 96 pages and E-ink with 116 pages.

Each friend you name signs at least one clue and stands in the register among the 5,000 guests, and the solution page shows which clue cleared each friend. Please use only the names of people who will be happy to appear in a game. We use the names only to build the case, and the files are deleted automatically 30 days after they are ready, so save your files.

It suits adults and teens who like logic puzzles and detective stories, and it works as a Christmas or Secret Santa gift for a group of friends. It is not the right pick if you want a role-play party game with characters and scripts, a quick game, a language other than English, something in the mail, or a Halloween case. The texts and puzzles were created with the help of AI tools, every page is drawn in code with no AI images, and the other names in the register were combined at random from public lists of common U.S. first names and surnames. If the small case above went well with your group, see the Christmas murder mystery with your friends as witnesses.
