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 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.”

“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.  “

Soaked in Dreams

“Cleverly blending local historical fact with fiction… the innovative theatrical/interactive murder mystery format is engaging… there were enough red herrings, rabbit holes and wild theories thrown into the mix by ImmerCity to keep us on our toes, and with this fun, multi-genre approach to immersive theatre, it’s a hugely entertaining way to spend the evening.”
