Masquerade murder mystery party
A masquerade was made for murder. Everyone arrives in disguise, nobody is quite who they seem, and New Year's Eve hands you a built-in deadline: the clock is racing toward midnight, and the killer has to be unmasked before it strikes twelve. The dress code is black tie with a twist (velvet, sequins, sharp suits and a mask for every face), so guests get to feel glamorous without hunting down a historical costume.
Killer Cast writes the case around your actual guest list. Each friend becomes a suspect at the Starfall Ballroom gala: the gala chair who set the clock four minutes fast, the mask maker who knows exactly who wore which face, the party photographer whose camera roll could sink anyone. Every guest gets a private invite page with their character and costume ideas and, if they add a selfie, an illustrated portrait wearing a jeweled mask. Secrets stay sealed until the party begins.
On the night, narrator audio with captions runs the rounds from your TV or laptop, while an interactive Evidence Locker unlocks items like dance cards, coat-check tickets and torn place cards. Start the case around 9:30 p.m. and about two hours of play brings you to the accusations and the big reveal just before the countdown, so you toast the new year with the mystery solved. Because everything is digital and ready in minutes, there's nothing to ship and no holiday mail to wait on. The costume, menu, decor and music ideas below are built for 6 to 20 adults and a party-sized budget.
The Starfall Ballroom at the top of the Wexley Grand Hotel, where the city's most glamorous guests ring in the new year behind masks. The champagne tower glitters, the emcee is warming up the countdown, and at midnight everyone unmasks. Everyone who's still standing, anyway.

Meet the
suspects
Peyton Lisle
The gala chair
Planned every detail of the Starfall masquerade, down to the color of the confetti, and takes any deviation personally. Peyton holds the seating chart, the master key and a grudge or two.
“Set the ballroom clock four minutes fast tonight, and won't say why.”
Costume ideas: A sleek black suit or gown with one gold accent, a clipboard and a gold pen, a gilded mask on a stick.
Sage Corvino
The mask maker
Crafted every mask in the room by hand, so Sage can recognize any guest by the curve of a feather or the glint of a gem.
“Made two identical silver masks this season and sold them to two very different buyers.”
Costume ideas: A velvet blazer or wrap dress in a jewel tone, a feathered, sequined mask of your own making, a ribbon measuring tape draped around the neck.
Arden Fairchild
The party photographer
Hired to capture every moment of the gala, from the grand entrance to the midnight toast. Arden's camera roll is the most complete record of the night, which makes it the most dangerous object in the room.
“Took a photo at 11:31 that someone has already offered to buy, at any price.”
Costume ideas: An all-black outfit with a camera strap across one shoulder, a disposable or toy camera, a sequined mask pushed up on the forehead.
Blair Devereux
The head sommelier
Poured every glass of champagne tonight and remembers who drank what, who refused a refill and who swapped glasses when they thought nobody was looking.
“Knows exactly which glass went missing from the champagne tower at 11:20.”
Costume ideas: A white shirt, black vest and bow tie, a white napkin folded over one arm, a corkscrew or tasting cup on a ribbon.
Tatum Wexley
Heir to the Wexley Grand Hotel
Inherits the family hotel at the stroke of midnight, as long as nothing scandalous happens before then. Tatum is charming, jittery and checking the time far too often.
“Becomes very rich at 12:00:01, if the night stays perfectly quiet until then.”
Costume ideas: A tuxedo or satin gown in midnight blue, a pocket watch on a chain, a silver mask set with a single jewel.
Phoenix Royce
The emcee
Runs the gala program from the welcome toast to the countdown, with a microphone, a stopwatch and a joke for every lull. Phoenix also holds the run-of-show, with every minute of the night accounted for.
“Stopped the music at 11:42 for an announcement that never came.”
Costume ideas: A sequined jacket or metallic dress, Cue cards tucked into a pocket, a gold mask with a dramatic flourish.
Quinn Marchbanks
The fortune teller
Hired to read tarot in a candlelit corner of the ballroom, Quinn gives each guest one fortune for the coming year. Most are cheerful, but one was alarmingly specific.
“Predicted a death before midnight, and now everyone wants to know how.”
Costume ideas: Layered scarves over a dark velvet outfit, Stacks of rings and bangles, a deck of tarot or playing cards.
Jordan Carrow
The uninvited guest
Nobody remembers sending Jordan an invitation, yet Jordan greeted the staff by name and knew exactly where the coat check was hidden.
“Arrived without an invitation, but with a key to the penthouse suite.”
Costume ideas: Any all-black outfit with a long coat, a plain black domino mask, an old brass key on a ribbon.

Dress the
part
For everyone
- Black tie, your way: a dark suit or tuxedo, a gown, a sleek jumpsuit or any cocktail outfit counts
- A mask is the one must-have. Half-masks, lace masks and masks on a stick all work, and stick masks are easiest for anyone who wears glasses
- Stick to the midnight palette: black, gold, silver, deep navy, emerald or garnet
- Add one luxe texture, like velvet, satin, sequins or metallic brocade, to make a simple outfit feel like a gala
- Give your character one signature detail, such as a single dramatic glove or a monogrammed pocket square, so other suspects remember you
- Wear shoes you can dance in: the dancing starts the moment the case is closed
On a budget
- Decorate a plain dollar-store mask with a gold paint pen, hot-glued sequins and a few craft feathers
- Print a mask template on card stock, cut it out and tape it to a chopstick or dowel for an instant mask on a stick
- Thrift a black blazer, dress or button-down and swap in gold buttons for a few dollars
- Glue sequins or glitter along the collar of an old blazer or the neckline of a plain top for instant gala sparkle
- Host a mask swap: ask everyone to bring a spare so nobody arrives barefaced
Accessories that sell it

Set the scene
- Clocks everywhere: print or draw clock faces all set to 11:59 and tape them to walls, mirrors and the front door
- Midnight-blue and silver balloons, plus a few clear balloons filled with confetti
- A short pyramid of plastic coupes as a centerpiece, filled with gold ornaments instead of bubbly to skip the mess
- A mask wall by the door: spare masks hung on ribbon for anyone who forgets theirs

- A gold tinsel curtain, or string lights behind a sheer curtain, as the photo backdrop
- Black tablecloths scattered with star confetti and battery tea lights
- Name cards handwritten in gold paint pen on black card stock
- Mirrors and silver trays set around the room to bounce the candlelight
Music
Glittering and suspenseful: champagne-bright at the door, darker and slower as midnight closes in.
- Baroque-style chamber strings and harpsichord for the masked arrivals, a nod to Venetian carnival
- Electro-swing for an upbeat, vintage-meets-modern cocktail hour
- Waltzes and tangos from small string ensembles while suspects circulate
- Low, moody solo piano and pizzicato strings under each round so voices carry
- A ticking-clock soundscape at whisper volume during the accusations
- Disco and modern dance-pop for the after-reveal party into the new year
Talk the
talk

Questions
Will the mystery get in the way of the midnight countdown?
Not if you time it right. Plan on about two hours from the opening scene to the reveal. Have guests arrive around 9:00, start the case at 9:30 and you'll be making accusations around 11:15, with the killer unmasked just before the clock strikes twelve.
Do guests have to wear masks all night?
No. Masks are for the grand entrance, the photos and the midnight unmasking. Masks on a stick are the most comfortable choice for glasses wearers and for anyone who wants to eat, drink and talk freely between rounds.
Will guests who aren't drinking feel left out?
Not at all. Nothing in the game involves drinking, every drink on the menu has an easy alcohol-free version, and the Silver Domino mocktail means everyone has something festive in hand for the toast.
How many people can play?
Every case is written for 6 to 20 players, and every guest gets a suspect role with a secret, a motive and clues to share, so nobody spends the evening as a bystander. Guests play from their private invite pages on their phones, or you can use the optional print-at-home kit.
Can I host and still play?
Yes. You can play a suspect alongside everyone else or run the game as the gala's host. Narrator audio with captions handles the scene-setting either way, so you can keep an eye on the bubbly.
It's already late December. Is there still time?
Yes. Your case is ready in minutes and everything is digital, so there's nothing to ship and no holiday mail delays. A week's notice is plenty for invites, and a dollar-store mask is a perfectly good costume.
