Ruth Rendell was once described in The Sunday Times as “the best woman crime writer since Christie” – so it seems fitting that Bill Kenwright’s Classic Thriller Company, having presumably run out of Agatha Christie stories to stage, has chosen one of Rendell’s most famous works for their latest production. A Judgement in Stone unpicks the story of a grisly mass shooting, but despite commendable performances from an impressive cast of household names, it doesn’t quite succeed in blowing its audience away.

Largely, I think this is simply because it’s not Agatha Christie. Her stories work on stage because often they take place in one location, so focusing all the action in a single room doesn’t feel limiting, and because they build to a big reveal of a shocking, clever twist based on clues that have been liberally scattered throughout the play. Rendell’s novel opens by revealing both murderer and motive; it wasn’t really intended as a murder mystery so much as an exploration of social class divisions in the 1970s. Simon Brett and Antony Lampard’s adaptation forces the story into the classic whodunnit mould, meaning a lot of that subtlety is lost, and we spend the whole evening waiting for a twist that, unfortunately, never comes.
That said, it’s an entertaining enough production, and director Roy Marsden certainly succeeds in ramping up the suspense, particularly in Act 2. The play opens some weeks after the murders of the wealthy Coverdale family, as a detective from London – called in by someone important in the Government – arrives to help the local police solve the crime. The story then unfolds in a series of flashbacks, beginning when Eunice first joins the family and building up to the night of the murder nine months later. In between, the two police detectives interview various suspects (at the murder scene, rather bizarrely) on their way to solving the crime, which eventually happens more by luck than judgement; there’s certainly no Poirot-esque flash of inspiration that suddenly makes sense of everything, and this also contributes to the play’s rather subdued conclusion.

The cast do a good job with some slightly sketchy roles (apart from one brief exchange about family life and fish paste sandwiches, for instance, we learn next to nothing about Chris Ellison and Ben Nealon’s police detectives, who only really seem to be there to set up the next flashback). Sophie Ward is great as the awkward, slightly eccentric housekeeper Eunice, while Deborah Grant has perhaps a bit too much fun as her religious fanatic best friend Joan, and there’s a solid performance from Blue’s Antony Costa as Rodger Meadows, the family’s gardener with a dodgy past.
Having seen and enjoyed several productions from the Agatha Christie Theatre Company, which work so well on stage, I can’t help but feel a little disappointed with this latest offering. But here’s a twist: I do now want to read Ruth Rendell’s novel. Although I don’t feel it entirely works as a play, the story and characters have enough potential that I’m intrigued to find out everything the stage version didn’t tell me. And fans of Ruth Rendell’s novels, who already know how the story ends, may enjoy this fresh take on a favourite.
A Judgement in Stone is at the Orchard Theatre until 30th September.
