1920s Murder Mystery Dinner Party: Menu, Décor, Game Guide

Table of Contents

There’s a reason murder mystery parties are one of the most requested dinner party themes of all time: they combine food, drama, costumes, and collaboration into a single evening that guests never forget. And when you set that mystery in the 1920s—the era of speakeasies, jazz music, and flapper dresses—you’ve got the ingredients for a truly spectacular night.

A 1920s murder mystery dinner party is much fun whether you’re a seasoned host or a first-time host tackling your very first themed evening.

The Roaring Twenties provide such rich visual and cultural material that the theme practically builds itself: the music, the cocktails, the fashion, and the intrigue all come together into a great time that feels cinematic.

This step guide walks you through everything you need—from choosing your murder mystery game to building a jazz-age speakeasy menu to setting the scene with period-perfect décor. Let’s get into it.

Choosing the Right Murder Mystery Game

The foundation of any murder mystery dinner party is the game itself.

For a 1920s theme, you want a game set during the height of Prohibition—think jazz clubs, crime bosses, and secret alliances. There are several excellent 1920s murder mystery game options available as both digital download PDF files and boxed kits.

Masters of Mystery offers a replayable Gatsby-era speakeasy game for 4–20 players that includes character booklets, detective audio files, and a detailed host guide—perfect if you want a polished, ready-to-run experience.

For something with a lighter, more theatrical twist, Maple Mystery Games’ 1920s Speakeasy kit features quirky characters like flappers, bootleggers, and a Temperance Society founder, along with printable decorations to transform your space.

When selecting your game, consider the number of guests, whether you want a scripted or improvised format, and the complexity level.

First-time hosts should start with a structured kit that includes character descriptions, game materials, clue cards, and a clear step guide for the host.

Night of Mystery offers downloadable kits with over 39 themes that include character packets, invitations, and a host guide designed so even beginners can run the evening confidently.

If you prefer a physical boxed set shipped to your door, Broadway Murder Mysteries creates games written by Broadway talent with simple pacing prompts and role assignments built right in. Many kits also include expansion packs for larger groups and extra copies of character sheets for easy access.

The best murder mystery games build suspense gradually across multiple rounds, ideally timed to coincide with each course of your meal. This creates a natural rhythm: appetizer and introductions, main course and investigation, dessert and the final reveal.

Look for games that have a fair-play solution—meaning guests have enough real clues to solve the mystery themselves.

💡 Host Tip for First-Time Hosts
Print character sheets and name tags at a local print shop on cardstock rather than regular paper. This small detail makes the entire party feel more polished and gives guests something tangible to hold as they slip into character. Having extra copies on hand helps if anyone forgets theirs or a last-minute guest arrives.

Setting the Scene: 1920s Speakeasy Décor

The glamour of the 1920s is all about contrast: dark, moody lighting against gleaming gold and silver accents.

To create a speakeasy atmosphere in your own home, start by dimming the lights and adding candles, string lights, and table lamps with warm bulbs. Think of it as transforming your dining room into the hottest hush-hush speakeasy in town.

Key décor elements for your 1920s theme include gold and black tablecloths or runners, art-deco-inspired centerpieces (think geometric shapes, feathers, and pearls), cigar boxes repurposed as card holders, and a dedicated cocktail station that looks like a Prohibition-era bar. Jazz-era product images and vintage posters add authenticity without much effort.

For music, build a curated Spotify playlist or curated jazz-age playlist featuring artists the era is known for. Hot jazz, swing, and crooner vocals create the perfect sonic backdrop. Play it at a volume that allows conversation but keeps the energy up—especially during the dance floor moments between courses.

The Jazz-Age Speakeasy Menu

Your menu should feel like something served at a glamorous 1920s dinner club. The jazz-age speakeasy menu doesn’t need to be complicated, but it should feel intentional and era-appropriate.

Prohibition-Style Cocktails

The Bee’s Knees is the signature cocktail of any 1920s party—gin, lemon juice, and honey syrup. It’s simple, elegant, and historically perfect. Alongside it, offer a Mary Pickford (rum, pineapple, grenadine) and a classic Old Fashioned.

For non-drinkers, create prohibition-style sips using the same flavor profiles without alcohol—the Bee’s Knees works beautifully as a mocktail with sparkling water. Vintage cocktails served in coupe glasses complete the look.

Elegant Canapés and Starters

Start with elegant canapés that feel luxurious but are easy to prepare: smoked salmon on rye points, deviled eggs with paprika, and stuffed mushrooms.

Art-deco nibbles should be bite-sized and easy to eat while guests are mingling, reading their character descriptions, and getting into the spirit of the evening.

Main Course

For the main event, think classic American fine dining of the era: beef tenderloin, roast chicken with root vegetables, or a rich mushroom risotto for vegetarian guests. Serve family-style to keep the conversation flowing and the lot of drama building.

The main course should coincide with the investigation phase of the game, so choose something that doesn’t require last-minute kitchen attention.

Dessert and the Final Reveal

Time dessert to coincide with the final reveal—when the guilty party is unmasked. A chocolate torte, crème brûlée, or a tower of profiteroles all feel appropriately decadent.

Serve alongside coffee and a final round of vintage cocktails. The combination of a dramatic reveal and an indulgent dessert creates the perfect ending.

Running the Game: A Step-by-Step Guide

Before the party: Send character assignments 1–2 weeks in advance so guests can prepare costumes and read their character descriptions. Include a brief note about the 1920s theme and dress code. If the game comes with game materials like clue cards or props, organize them into envelopes for each round.

Round 1 (Appetizers): Guests arrive in character. Serve cocktails and canapés while introductions happen. This is where the building suspense begins—everyone is sizing each other up, and first impressions matter.

Round 2 (Main Course): The mystery deepens. Distribute the next set of clues and let guests interrogate each other over dinner. Encourage table conversation—the best murder mystery parties are the ones where guests stay in character and test alibis naturally.

Round 3 (Dessert): The final reveal. Guests make their accusations, the truth hides no more, and the guilty party is revealed. This is the climax of the evening—make it theatrical. Dim the lights, pause the music, and let the drama play out.

After the reveal: Drop character and debrief. This is where the fun experience turns into stories—everyone shares what they suspected, what surprised them, and their favorite moments. It’s loads of fun and often the part guests remember most.

⚠️ Common Mistake
Don’t overwhelm guests with too much reading material. The best murder mystery games keep character sheets to one page and clue cards to a few sentences. If people feel like they need to study before attending, the fun evaporates. Keep it accessible—especially for younger players or first-time mystery participants. Good clean fun should be the goal.

1920s Dress Code Ideas

The dress code is what takes a 1920s murder mystery dinner party from fun to unforgettable.

Encourage guests to go all in: flapper dresses with fringe and beading for women, pinstripe suits or suspenders with fedoras for men. Pearls, feather headbands, and art-deco jewelry complete the look.

For guests who don’t want to go full costume, suggest simple additions: a string of pearls, a bow tie, or a pocket square can signal the era without requiring a full wardrobe change.

The key is making everyone feel like they’re stepping into a different world for the evening—which is exactly what makes the entire party a full immersive experience.
