How to Throw a 1920s Murder Mystery Dinner Party

Table of Contents

The 1920s—the Jazz Age, the Roaring Twenties, the era of flappers, speakeasies, and scandalous intrigue—provides the perfect backdrop for a murder mystery dinner party. The decade’s aesthetic is instantly recognizable and endlessly entertaining, making it one of the most popular themed dinner party formats for groups that love drama, costumes, and immersive storytelling.

This step-by-step guide walks you through everything you need to host a 1920s murder mystery dinner party that your guests will talk about for years. From character assignments to menu planning to set design, consider this your complete hosting blueprint.

🎭 What Is a Murder Mystery Dinner Party?
A murder mystery dinner party is a themed event where guests play assigned characters and work together (or against each other) to solve a fictional crime. The story unfolds in rounds, usually timed to courses of the meal, with clues and revelations building toward a dramatic conclusion. Most events use a pre-made kit with character guides, clue cards, and a host script.

Step 1: Choose Your Murder Mystery Kit

You do not need to write your own mystery—there are excellent pre-made kits available for every group size and budget. Look for kits specifically set in the 1920s or Great Gatsby era. Amazon’s murder mystery party selection offers a wide range of options, and free downloadable versions are available from sites like My Mystery Party. Choose a kit that matches your group size—most work best with 8 to 12 players.

Step 2: Assign Characters and Build Anticipation

Send character assignments two to three weeks before the event. Include each character’s backstory, personality traits, and costume suggestions. Encourage guests to start thinking about their outfits—feathered headbands, pearls, suspenders, bow ties, and pin-striped suits are all era-appropriate. As our article on building guest anticipationexplains, early preparation deepens engagement and makes the event feel more immersive.

Step 3: Plan a 1920s-Inspired Menu

The 1920s dining scene featured elegant simplicity—think cocktail shrimp, deviled eggs, beef tenderloin, and layered cakes. Serve your menu in courses timed to the mystery rounds:

Welcome Course (Round 1): Prohibition-era cocktails (gin fizz, sidecar, or a “bathtub gin” punch) with canapés and deviled eggs.
Main Course (Round 2): Beef Wellington or roasted chicken with duchess potatoes and glazed vegetables.
Dessert (The Big Reveal): A show-stopping cake or bananas Foster, served as the final clues are unveiled and the murderer is revealed.

Have fun with themed food and drink names: “The Suspect’s Sidecar,” “Poison Punch,” and “Deadly Chocolate Mousse” add playful energy. For menu planning guidance, check out Food & Wine’s library of elegant entertaining recipes.

Step 4: Set the Scene

Ambiance is everything for a murder mystery dinner party. Transform your space into a 1920s speakeasy with these elements:

Dim lighting with candles, Edison bulbs, or fairy lights strung in glass jars.
A jazz playlist featuring artists like Louis Armstrong, Duke Ellington, and Billie Holiday.
Art Deco-inspired table settings: gold charger plates, crystal glassware, black napkins.
A designated “crime scene” area with props and clue cards.
Printed menus and character name cards for each place setting—our Murder Mystery Party Event Templateswork beautifully for this.

Step 5: Host Like a Pro on the Night

As the host, you will likely play a character as well, so prepare as much food as possible in advance. Keep the evening’s flow on schedule by introducing each round at the beginning of each course.

🔍 Insider Tip: The Post-Reveal Debrief
After the murderer is revealed, give the group 15–20 minutes to debrief and discuss their theories. This unstructured conversation is often the most enjoyable part of the evening—let it breathe. Serve dessert and after-dinner drinks during this time to keep the energy flowing.

Frequently Asked Questions

Q: How many people do I need for a murder mystery dinner party?

Most kits are designed for 6 to 12 players, with 8 being the sweet spot. Fewer than 6 can make the mystery too easy to solve, while more than 12 can become logistically complex. Check your kit’s player range before sending invitations.

Q: Can I host a murder mystery dinner party in a small space?

Absolutely. Murder mystery parties work in any space where guests can be seated together. A dining room table or even a living room arranged with cushions and trays works well. The NYT’s tips for small-space hosting can help you maximize your layout.

Q: What if some guests are shy about acting?

Assign quieter guests roles that are observers or investigators rather than central suspects. Most kits include a range of role types. Emphasize that the goal is fun, not Oscar-worthy performances.
