A country gentleman's tranquil life is disturbed by a small domestic alarm that presages escalating intrigue: petty mischief develops into theft and accusation, unsettling a tight-knit rural household.

The narrative moves from garden-side intimacies to procedural investigation, exposing conspiracies and hidden loyalties before disclosing the facts behind the wrongdoing.
