About the murder mystery events we hold at The Mandeville Hotel

The murder mystery plot

We offer a choice of two murder mystery plots at this venue, Sherlock Holmes: The Case Of The Magician’s Inventor and Dead Dogs Tell No Tales.

Sherlock Holmes: The Case Of The Magician’s Inventor – Queen Victoria is dead. The British Empire is at its height, but from ‎across the shores a storm is brewing, a storm that could change the whole world forever. What is the link between world politics, a rundown theatre in the West End and an eccentric inventor? Travel back in time and meet the master detective, Mr Sherlock Holmes, as he unravels the case.

Dead Dogs Tell No Tales – London, the 70’s. Criminals and the Flying Squad at each other’s throats. Now a case to blow everything apart – Terry ‘The Dog’ Mitchell, small-time crook, has been found murdered. But Terry knew a secret, a secret which could shake London to its very core. A new, exciting interactive murder mystery from West End Events and the chance to step into the shadowy world of 1970’s London crime.

Group sizes

We require a minimum of 15 people at this venue, of which,  8 to 12 will play the part of suspects. Any guests above this number need not be left out though as there are plenty of jobs for willing detectives; making notes during the suspect testimonies, examining clues and trying to uncover the murderer.

For groups of 26+ a second actor playing the part of an assistant detective is included free-of-charge. 

Groups of 33+ should contact us to discuss other venues that are more suited to higher numbers.

Format of the murder mystery

Ahead of your murder mystery at the The Mandeville Hotel, a number of your guests will be supplied with clues, secrets and motives which will see them suspected of committing the most horrendous of crimes (have you guessed what it is yet!?). Then, on the day in question, our detective will attend the venue to quiz the suspects. The plot will unfold as each guest discovers their part in the events that resulted in a murder, finally leading to the shocking revelation that one of them is a killer!

The interactive nature of this event makes it perfect for a variety of different occasions including team building days, birthday parties and hen nights.

Reasons to hold your murder mystery at The Mandeville Hotel

Venue location and style

The Mandeville Hotel is a luxury boutique 4 star hotel situated in Marylebone, just a 3 minute walk from Oxford Street. The nearest tube station is Bond Street. The retro decor in the bar & private dining rooms alongside the generous number of choices on the banqueting menu make this a brilliant choice for your interactive murder mystery dinner.

Private dining spaces at The Mandeville Hotel

The Voyager Room (up to 32 guests) has a quirky but classy design – a great alternative to some of the more business-style meeting rooms found at many other other hotels.

Venue reviews

For us, the choice of 3 starters, 3 mains and 3 desserts make this venue a definite winner. And that’s before you take into account the excellent service and boutique room design. But regardless of our thoughts, we’d recommend you check-out some independent reviews on The Mandeville’s TripAdvisor page first. If for any reason you’re still not sure then why not hire a murder mystery actor to come to a venue of your choice.

Our interactive murder mysteries can be tailored to run to your schedule, whether around a lunch or a dinner. But as a rough guide the murder mystery parties usually follow the following format:

7.00pm – Guests arrive for Prosecco welcome drink

7.30pm –  Murder mystery begins

7.50pm –  Dinner is served

10.00pm – Carriages

Please treat the above as a guide rather than an exact schedule.

At all of our parties we want our guests to feel comfortable and have a great time.

Our interactive murder mystery nights work really well when guests dress up as the parts that they will be playing. For instance, a police officer or wealthy baroness. That said, we don’t enforce a dress code so we’ll leave the decision up to you and your guests

We cater for all dietary requirements and these can be noted on the paperwork we send once you have booked. The only exception is kosher which requires specialist caterers so please contact us for more information.

We require a deposit of £30+VAT per guest in order to secure your booking, the final balance is due four weeks before the party.

“…Thank you so much for a wonderful event.
The entire night was a success with our staff all saying how much fun they had.
It was really well organised, the actor was fantastic and the venue was great as well. We would recommend the event to others as a brilliant night out”

What preparation is required for the event?

You’ll need to invite your guests and then provide us with a list of their names. You’ll also need to let us know which of the guests is playing the part of a suspect.

The actor will contact the suspects with their character information and let them know what to expect. The suspects will need to familiarise themselves with a small amount of information but there are no scripted lines to rehearse. All of the questions the detective asks them during the murder mystery can be answered from the notes we provide.

We’ll ask the organiser to fill in a function sheet detailing any dietary requirements, menu selections (where applicable) and optional drinks orders.

If you’ve decided to dress up you’ll need to think about your costumes. Suspects can be guided by their character information, other guests can go for anything that fits with the theme you’ve selected.

The booking process 

The first step is to contact us and check availability of your preferred date and time. If you decide to go ahead we’d issue an invoice which can be paid via bank transfer or credit / debit card (we accept American Express). We take a deposit payment of £30+VAT per person at the time of booking with the final balance due 6 weeks prior to the event.
