What’s On


The wedding of East End gangster, Jim Slice, in July 1955 is remembered for two things: the Slice family’s notorious reputation and the fatal stabbing of the priest before the ceremony could start. Despite numerous allegations and suspicions, the murder of Reverend Gris was never solved. We are calling you to step back in time, to that fateful day, and investigate the truth behind a close knit community torn apart by World War Two, rebuilding life from the rubble. Uncover a seething pit of family in-fighting, war-time secrets, blackmail, smuggling, and, of course, murder… 

Coming this summer to the stunning church and surrounding graveyard of St Matthews in the heart of Bethnal Green. Solve the murder in groups of 5-8! So come with friends or make some on the day. 1950’s wedding attire encouraged!

THE SHOW WILL GO AHEAD RAIN OR SHIN- though some sections may be adjusted to be performed inside!

There are disabled access routes so please email info@immer-city.com before booking and/or talk to box-office on arrival to ensure you are set on the right route.


“The Unholy Marriage… is a superb collision of the atmosphere of the venue, the history of the area and a well-plotted and engaging drama that throws you into the heart of the action. It offers three very different acts – all of which were tightly plotted, gripping and excellently directed. ”

Soaked in Dreams 


““ Cleverly blending local historical fact with fiction… the innovative theatrical/interactive murder mystery format is engaging… this fun, multi-genre approach to immersive theatre, it’s a hugely entertaining way to spend the evening.”



“An enjoyable, immersive murder mystery, elevated by a superb cast, that delights in its unusual setting”

The Stage

July 18th – September 6th 2019


Join us for a sinister evening of theatre, puzzle solving and ghostly encounters. 

It was 1871, and every level of the pumping station was bustling with activity in preparation for the grand opening of the 100” Cornish Engine, when two unexpected guests from the workhouse arrived demanding to see the small boy who had been apprenticed to the Chief Engineer.

Now, more than a century later, a child’s crying has been heard from beneath the Cornish Engine and it is starting to unnerve the tourists. The Museum has invited the master of the supernatural, Jack Daw, to awaken the past and uncover the truth.

You must solve the mystery in groups of six so bring friends or we can put you into a group with other audience members on the night.

Victorian High Tea is included in the ticket price. Drinks for the interval can be pre-ordered at the cafe between 7.15 and 7.30pm.

High Tea includes vegetarian options. If you have any other dietary restrictions please email info@immer-city.com before buying your ticket.

Unfortunately this show is not wheelchair accessible.

“Think of an interactive murder mystery in which you, the audience, must solve the crime, and you’ll probably imagine a seedy hotel ballroom in the off-season downtime. But The Silhouette in the Smoke is a genre-busting show that breathes new life into a tired genre….This is a show that achieves all it sets out to do, with wit and style. The magnificent surroundings of the pumping station provide the perfect backdrop, and the actors’ characterisation never wavers under pressure. A hugely enjoyable evening, which cannot be recommended too highly. (And the high tea was a real bonus.)”
Everything Theatre

“…the looming threat of the powerful machines all lend a deliciously gloomy air of menace and otherworldliness to the proceedings…It’s all about the fun of the chase, the atmosphere and the escape from the cold, dark reality of January. Theatre doesn’t get much more interactive or much better than this.”

September 9th – 19th


An Immersive Cold War Thriller. Come and solve the mystery of the man who died in the archives at Kensington Central Library.

The old librarian, Gwendolyn Radcliffe, never forgot that fateful night in June 1962. Esteban Moreño’s lecture on Cuban music was poorly attended. His meagre audience was composed of herself, a young journalist, his model girlfriend, a Mathematics student and a drunken vagabond. However, the event made the news when the drunk was found dead beneath the Library less than an hour later. The police never identified him, but from then on Gwen often felt she could see the haunting shadow of a sleeping man, slumped among the shelves.

Now in 2018, Gwendolyn has discovered that an undercover agent named ‘Anillo Rojo’ disappeared in London that very same night. She has hired the master of the supernatural, Jack Daw, to investigate this mystery. He is looking for bright minded people to join him and unlock the dark past of the Library.

Jack Daw will put you into groups of five or six, one to focus on each suspect, so bring friends or make new ones on the night. The is free tea, coffee and lemonade in the interval.

Dead Quiet has been created with an exhilarating mix of historic facts and classic sixties spy stories.


All interactions are initiated by the audience and you will not be called on to do something you are uncomfortable with.

The show does involve a fair amount of walking around the space and travelling up and down stairs so please wear sensible shoes.

We have one wheelchair accessible route but due to the size of the lift this is limited to one per show.

If you have any questions please email info@immer-city.com before you book to ensure we can accommodate you.
