What is a 1920s Murder Mystery Party?

A 1920s murder mystery party is an interactive event where every guest takes on the role of a unique character in a thrilling whodunnit set during the glamorous Roaring Twenties. As the story unfolds, players uncover clues, question suspects, reveal secrets and work together to solve the crime, creating an unforgettable experience filled with laughter, suspense and memorable moments.

Why the Roaring Twenties make the perfect setting

The Roaring Twenties is one of the most popular themes for murder mystery parties thanks to its fascinating blend of glamour, prohibition, jazz music, gangsters, flappers and hidden speakeasies. The era naturally lends itself to mystery, intrigue and larger-than-life characters, allowing guests to dress up, embrace the atmosphere and immerse themselves in a world of secrets and deception.

Great Gatsby vs Gangster themes

While both themes capture the spirit of the 1920s, they create very different party experiences. A Great Gatsby-inspired event focuses on elegance, luxury and high society, with lavish costumes, champagne and extravagant décor. A gangster-themed party leans into organized crime, bootlegging, rival gangs and smoky speakeasies, creating a darker and more dramatic atmosphere. Both styles work exceptionally well for a murder mystery, so the best choice depends on the type of experience you want your guests to enjoy.

In both cases you will play our Tracy Gang 1920s game but the vibe of your event will be different.

Understanding your 1920s Murder Mystery Party

Before you start planning your event, it's helpful to understand how a murder mystery party is structured and what your guests can expect. Unlike a traditional dinner party or themed celebration, a murder mystery places everyone at the center of the action. Guests become characters, uncover clues, question suspects and work together to solve the crime, creating an experience that's both entertaining and highly memorable.

How a murder mystery party works

Each guest is assigned a unique character. Throughout the party, players interact with one another, share information, uncover clues and try to determine who committed the murder. The presenter guides everyone through the different stages of the game, introducing new clues and helping the story unfold until the dramatic final reveal. No acting experience is required and guests simply enjoy stepping into character and having fun.

How interactive guests should expect the game to be

Murder mystery parties are designed to be highly interactive, but participation happens naturally through conversation rather than formal acting. Guests spend most of their time mingling, asking questions, making accusations and piecing together the mystery. Some players love fully embracing their character with dramatic accents and costumes, while others prefer a more relaxed approach. The beauty of a well-designed murder mystery is that everyone can participate at their own comfort level while still playing an important role in the story.

How long a typical murder mystery party lasts

Most 1920s murder mystery parties run for between 2 and 3 hours, depending on the number of guests and whether you include a meal. Smaller cocktail-style events can often be completed in around two hours, while dinner parties and larger celebrations typically take closer to 3 hours. Allowing plenty of time between clue rounds gives guests the opportunity to socialise, enjoy the food and drinks, and fully immerse themselves in the mystery without feeling rushed.

Organizing your 1920s Murder Mystery Party

Choosing the right date

A 1920s murder mystery can be held anywhere, anytime. Of course Friday, Saturday and Sunday are the prime days. If alcohol will be included then Friday and Saturday are best and I have been to many fabulous Sunday mysteries but you have to remember that people often have work the next day. Perhaps a Sunday afternoon is best with an early finish.

You can purchase, download and play your 1920s murder mystery in a couple of hours but I suggest planning your event at least 6 weeks out so you have plenty of time to get organized.

Setting a realistic budget

You should consider budgeting for the following items:

• Your Tracy Gang 1920s game
• A professional presenter if you are not going to run it yourself
• Venue hire
• Decorations
• Costumes
• Food and drink

Choosing your guest list

Invite friends, colleagues, neighbors family and loved ones. Something to consider are kids. Parents with young children often won't be able to stay until the end of the game. It is important for your presenter to know if people have babies at home because you don't want them making that person the killer only to announce that an empty chair is the murderer.

Selecting the perfect venue

The 1920s is a classic venue theme and many towns have a 1920s style venue. If you want to keep things easy or keep the cost down you can definitely have your 1920s party at home.

Look for an art deco style building with lots of old world charm. Some things to be mindful of with your venue:

• Guests need enough light to read, but you want your venue to be dimly lit
• Ensure the venue doesn't have piped 1920s music that you can't turn off as your guests need to be able to hear
• Have enough open space to freely move (and maybe dance the Charleston) but you don't want a huge venue for your group size

Planning for decorations

In short, think dark, dingy and hiding from the law while still having a great time. The basic color palette is black, white and red.

Visit our ultimate 1920s decorations page for our full guide on setting the scene.

Encouraging costumes

Costumes are never essential but they do make the event better. A guest in costume is a different person and they take on a whole new persona. Encourage your guests to dress up if you can.

Sometimes, you don't want to impose on your guests or maybe you are a work group and everyone is dressed for the office. In that case, get feather boas and cheap gangster hats from Amazon and make the arrival of your guests a fun part of the event as you dress them in boas and hats.

Inviting Your Guests

Your game comes with digital invitations that you can download and email to your gusts. You should send your invites as early as possible so people can set the date aside.

The invitations include all the vital information like the event, date, time and location of the venue. Costume suggestions are clearly included and the invitations will help get your guests excited about the mystery to come.

Make sure you collect RSVPs so you can plan catering and check in with your guests 1 week before the big night.
