When young Eric, an orphan raised by nuns (played by Ben Radcliffe), is dispatched to deliver a message to Lord Davenport (Damian Lewis) at his grand estate, he's quickly mistaken for someone applying for work and hired as a hall-boy. He’s resourceful and quick-witted, so he rapidly climbs the ranks behind the scenes and even catches the eye of the lord’s daughter. Previously, on his arrival, he had an awkward encounter with Rose (Thomasin McKenzie), who feels somewhat responsible and is also drawn to his charm. However, her father insists she marry Archie (Tom Felton) to save the family from financial ruin—a prospect they are completely unprepared for. Determined Rose rejects this arranged marriage plan and considers running away with Eric until a body is discovered, prompting the arrival of a mustachioed police inspector, Watt (Tom Woodman-Hill), to investigate this unusual crime. With numerous suspects and possible reasons for the death, the investigator’s attention naturally falls on the handsome but impoverished young man hoping to marry into the family. Could he be the culprit? While there are some enjoyable parts, the film brought to mind Dawn French's "Murder Most Horrid" (1991), along with elements of "Downton Abbey” and a “Knives Out”-style mystery. It attempts to critique rural England’s upper class—their lifestyles and perspectives—but does so without much originality. Supporting players like Sue Johnston (resembling Dame Maggie Smith), Anna Maxwell Martin (like Phyllis Logan as "Supergran"), and Hayley Mills are given limited roles, preventing them from having a significant impact on the story, which shares similarities with Agatha Christie’s works. The ending comes unexpectedly, resolving questions about characters we barely knew existed. It's not a mystery that invites audience participation; instead, one hopes the humor will carry the film. For me, a vicar misreading scripture in a comical fashion just didn't provide enough entertainment. Damian Lewis seems to be trying to have fun, but even he appears puzzled by what’s intended to be humorous as it descends into silliness. It’s supposed to be a satire, perhaps even a satire of satire, but I simply didn’t find it funny, unfortunately.
