AN OUTDATED STYLE

There is absolutely nothing better than hopping on a train out of London on a gorgeous, sun-drenched Saturday afternoon. My destination yesterday was the delightful Mill at Sonning. This was my very first time visiting this historic venue, and let me tell you, the welcome alone was worth the journey. The reception here is incredibly warm, and the legendary pre-show two-course meal was absolutely gorgeous. I opted for the steak, mushroom, and ale pie followed by a chocolate and cherry mousse, and it was honestly to die for - comfort food at its absolute finest.

Stuffed and happy, we headed into the auditorium, where we were met with a gaudily decorated hair salon. The bright colour palette instantly reminded me of an interior straight out of The Simpsons. The show actually starts before the official curtain time, with the actors already on stage, giving us a window into the everyday, chaotic goings-on of a busy salon. This is a creative choice I always enjoy.

Now, if you don't know the history of SHEAR MADNESS, it’s a bit of a theatrical juggernaut. It actually started back in 1963 as a serious German psychological drama called Scherenschnitt, meant to test human perception. In the late 70s, it was bought by American producers who injected it with farce, and it somehow went on to become the longest-running non-musical play in US history. The plot itself is a classic whodunit. A wealthy pianist is murdered upstairs, the salon is locked down, and the audience has to help the police solve the crime.

This should have been a slam dunk for me. As a huge Agatha Christie fan, I love a good murder mystery - and trying to work out "whodunit" in real time is something I almost always enjoy.

Unfortunately though, the wheels started to come off from the very beginning. The glaring problem with this show is just how dated it feels. Even though they’ve tried to modernise the piece by setting it in Sonning in 2026, throwing in local references to Henley and jokes about Nigel Farage, it doesn't eradicate how stale and boring the core storyline is. It also suffers from a massive identity crisis. Unless a line has been specifically altered to reflect the local Berkshire area, the script remains aggressively American. For example, as a qualified hairdresser myself, I can tell you that we over here would never refer to our scissors as "shears".

My biggest grievance, however, was the character of salon owner Tony Whitcomb. In today’s world - and particularly ironic on the exact day London was celebrating Pride - we were handed a character that was nothing more than a walking stereotype. Tony has had every single outdated, flamboyant gay trope thrown at him. Instead of feeling like a fun queer character, he came across as a dated relic from a bygone era of theatre, and frankly, it felt offensive. In 2026, we should be way past using cheap, camp stereotypes as an easy punchline.

The rest of the characters didn’t really work for me either. We’re given a police detective who constantly confuses basic words - such as "lesbian" and "Lebanese." It’s tired, lazy writing, and I quickly found myself frustrated and annoyed by him. Because the script itself is so poor, a lot of talent on that stage felt completely wasted. Before the murder happens, the first act heavily lacks momentum, leaving us with characters that feel unlikable, wooden, and entirely one-dimensional. Theatre like this should be exciting and demand your attention.

The ultimate saving grace of this production is when the audience finally gets involved. SHEAR MADNESS relies heavily on audience interaction, and thank goodness it does, because that was the exact moment some life was finally injected into the room. The audience really were the stars of the show. I didn't laugh a single time until the house lights came up and the public took over. An older gentleman sitting in the front row was a particular favourite of mine, matching the energy perfectly, and giving the cast the run around.

The only downside to this interactive free-for-all is that when we were invited to investigate the murder and evaluate the evidence, it gave the audience licence to talk amongst themselves and shout over one another, which got a bit chaotic.

That being said, this is where the cast really came into their own, showing off some great improv skills and quick-witted interactions with certain crowd members. At the end, we're asked to vote on who we think the prime suspect is, and that person is eventually revealed as the murderer. It’s an interesting gimmick because it means there’s a different outcome every night, but it also exposes why the beginning of the play feels so weak - the story can't have a clearly defined arc if the ending changes on a whim.

The cast did well considering what they were working with, and Jonathan Markwood was my absolute standout performer. He grounded the madness and felt like the most believable person on stage.

Ultimately, I find it hard to believe how this has managed to be the longest-running non-musical show in America. Maybe they just have a very different sense of humour across the pond!
