The one night dressing up needs no excuse

The Halloween Files

Everyone already wants to come in costume. Give the costumes a plot. A murder mystery is the Halloween party with a body in the next room, a room full of suspects, and a killer sitting at your table, passing the pumpkin soup.

The short answer

The Halloween Files are six Halloween murder mystery party games for adults, all original fiction. The case plays on your television, every guest gets a private dossier on their phone, and every character has a costume note. No gore required. A$39 a case, with instant access.

Six Halloween-native cases, written for the thirty-first and ready to host tonight. $39 each.

Why Halloween hosting works

The costumes are sorted.
Now give them a reason.

01

Half the work is done

On any other night, talking your friends into costume is the hard part. On 31 October they arrive dressed and in character before you open the door.

02

Dread beats gore

Our cases run on candlelight and suspicion, not fake blood. The scariest thing in the room is the person who knows more than they are saying.

03

A party with a plot

Most Halloween parties peak at the costume judging. This one builds all night, to an accusation the whole table has to make out loud.

04

Strangers become suspects

Mixed group of friends, workmates and plus-ones? Perfect. Nothing introduces people faster than accusing each other of murder.

For the halloween party ideas list

One idea that does not stop
at the costume photo.

Search halloween party ideas for adults and you get the same handful back: a costume contest, a horror movie marathon, a blind cocktail tasting. All fine, all over in about the time it takes to judge a costume or start a film. A murder mystery halloween case is the one idea on that list built to run the whole night, because the plot does not resolve until the last guest names a killer out loud.

It also solves the actual problem with most adult Halloween parties, which is not the decorating. It is the hour after everyone has admired each other's costumes and the room does not know what to do next. A case gives it something to do next.

How the app runs the night

Your TV is the stage.
Their phones are the wings.

01
Phones out
Each guest gets a private dossier on their own phone: who they are, what they want, and what they would rather nobody found out.
02
Screen on, and you hold the remote
The case plays from your television, but nothing on that screen moves unless you say so. Your own phone is the control room: it shows what the room is about to see, what to say if the conversation stalls, who is sitting on which secret, and a Next button. Nothing advances on a timer, so if the main course runs long or the room is enjoying an argument, you simply let it run and press on when you are ready. Scenes and evidence land on the television for everybody; the secrets stay on the phones.
03
Host haunts
You play the victim, in costume, obviously. Greet your guests, die beautifully, then drift about refilling drinks while they argue over who wanted you gone.
04
Verdict
Evidence arrives in stages, theories rise and fall, and the night ends with the whole table naming a killer on the record.
The Halloween Files

Six cases written
for the thirty-first.

These are not the historical Case Files. The Halloween Files are original fiction, six invented houses and villages and rocks, each built for one night of the year. Nothing in them is supernatural. Every haunting has a living hand behind it, and your table can prove which one. Six to twelve players, about ninety minutes, $39 a case.

File Two

The Séance at Ravensmere

Ravensmere House, Norfolk · All Hallows' Eve 1923

The medium is dead in the high chapel, behind a door that was locked, inside a circle of joined hands. Nothing here is supernatural. The séance is a fraud, the darkness is a stage effect, and the room can prove exactly how a living person did it.

File Four

The Anatomy Theatre

Merchiston Medical College, Edinburgh · 31 October 1888

The professor is dead in his own lecture theatre, in the year the city least wanted another body. Six of his colleagues have a reason and a scalpel, and one of them has been telling the truth in a way nobody has noticed.

Practical host notes

Running the night

Costumes

Every role comes with a costume note, so guests can dress to the case rather than guessing. The six files run from 1888 to 1971, so a hat and an attitude do most of the work.

Numbers

Cases play best with 6 to 12. Fewer than six, the two-player Case Files suit better. More than twelve, extras make an excellent jury.

Food

Serve things that survive interrogation: one-hand food, a slow dinner between acts, dessert saved for the verdict. Nobody cross-examines well over a roast.

Light

Candles, lamps, the TV glow. Keep the overheads off and the phone torches for the evidence. Dread is a lighting decision.

The host's death

You are the victim, so plan your big moment: a toast, a scream from the hallway, a dignified collapse. Then enjoy the rare pleasure of watching your friends fight over your memory.

Phones charged

The evidence arrives on your guests' phones in stages, so ask everyone to arrive charged. A charger basket by the door has saved more than one investigation.

Questions

The Halloween Files,
answered.

Is a Halloween murder mystery party gory?

No. The cases run on candlelight and suspicion rather than fake blood. The most unsettling thing in the room is the person who knows more than they are saying.

How many people do I need for a Halloween murder mystery?

Cases play best with six to twelve players, plus you as the victim. With fewer than six, the two-player Case Files suit better. With more than twelve, the extras make an excellent jury. The general hosting guide covers casting and running the night in full.

Do guests need costumes?

Halloween is the one night everybody already arrives in costume. Each character comes with a wardrobe note so guests can dress to the case rather than guessing. The six Halloween Files run from 1888 to 1971, so there is a period to suit whatever is already in the dressing-up box.

Does the host get to join in?

The host plays the victim, in costume. You greet your guests, die early, and then get to watch the accusations land without running anything.

How do I add a murder mystery to my Halloween party?

You do not need to redesign the night around it. Run drinks and costumes on arrival as normal, then start the case once everyone has eaten, somewhere between eight and nine. It runs about ninety minutes from the first scene to the killer being named, which leaves the rest of the night free either side. Nothing needs printing beforehand and nothing needs decorating beyond what you have already put up.

This Halloween,
the killer brings a plate.

Pick a case, send the invitations, and let the costumes do what they were always meant to do.
