Entertaining Murder – Upstairs at the Gatehouse

Entertaining Murder is a musical inspired by the true story of Edith Thompson, played by Daisy Snelson, and her young lover Freddy Bywaters, played by Dominic Sullivan.

This is a fascinating story, and the production adapts it for the stage with real clarity and purpose. The narrative is well structured, with each character given space to develop. Sue Kelvin, who portrays Avis Graydon and also acts as narrator, is particularly effective in guiding the audience through the events. Through her narration, we are encouraged to question what actually happened: who murdered Edith’s husband, what motives were at play, and whether each individual can truly be considered guilty. It also raises a broader moral question about justice and whether those involved deserved to face execution for their actions.

The production is carefully crafted, leading the audience through the story in a way that feels both engaging and thought-provoking. Rather than simply presenting events, it encourages reflection, allowing viewers to form their own opinions about the characters and their decisions.

Alex Cosgriff, who plays Percy Thompson, Edith’s husband, along with a range of other supporting characters, delivers an outstanding performance. His ability to switch between multiple roles brings real depth and variety to the production. He moves seamlessly from moments of comedy to more serious and dramatic tones, demonstrating impressive range and versatility.

Cosgriff and Dora Gee, who plays a young Avis Graydon alongside several other roles, are both especially strong in the number See Edith Thompson Swing. This song stands out as a highlight of the production. It captures the darker humour of the piece, particularly the unsettling public fascination with executions at the time. The depiction of people queuing and treating a hanging almost as entertainment is both shocking and compelling, highlighting the historical attitudes of the era.

At times, it is uncomfortable how such a serious subject is presented in a comedic way, yet it is handled skilfully enough that the audience is left both laughing and unsettled.

However, aside from this standout number, some of the other songs are less memorable. While well performed, they do not always remain with the audience after the show. Stronger, more distinctive musical themes could further elevate the production and enhance its lasting impact.

Overall, this is a brilliant and thoughtfully staged production, with a talented cast who each deliver strong performances throughout. Entertaining Murder leaves the audience questioning long after the final scene and is well worth seeing to experience the story for yourself and decide who you believe truly murdered Percy Thompson.
