Overview

England, 1925. At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong. It will be up to the unlikeliest of sleuths—the fizzingly inquisitive Lady Eileen 'Bundle' Brent—to unravel a chilling plot that will change her life, cracking wide open the country house mystery.

Why fans love it

The 1925 setting offers a sharp backdrop for a genre defined by hidden motives and social decorum. Rather than relying on standard detective tropes, the narrative places the impetus for solving a fatal country house prank on an inquisitive socialite. This shift from professional investigators to an accidental sleuth changes the stakes, turning a formal gathering into a high-pressure environment where every guest holds a secret.

Mia McKenna-Bruce anchors the investigation as a protagonist who navigates the constraints of the era while dismantling the facade of the English upper class. The pacing favors tight observation over spectacle, drawing connections between disparate pieces of evidence to reveal a deeper, sprawling plot. It is a calculated exercise in tension that treats the clock as a symbol of both the period and the rapidly fading innocence of those involved.
