Under the shadow of ancient stones, Shakespeare’s words echo through the summer air as the audience watches Julius Caesar’s assassination scene—until actor Gordon Mason collapses, real blood pooling beneath his costume. The prop daggers have been replaced with a genuine weapon, transforming cultural entertainment into murder.

Detective Inspector Keith Tremayne and Sergeant Clare Yarwood confront the ultimate locked-room mystery—a killing performed before dozens of witnesses, yet somehow unseen. The all-female amateur acting troupe falls under intense scrutiny, each member a potential suspect in a meticulously planned crime.

The suspects represent a fascinating cross-section of local society: Rachel Harrington, the shrewd estate agent; Elizabeth Morton, a detail-oriented accountant; Sophia Chen, a troubled teenager; Margaret Williams, a compassionate funeral director; and Victoria Blackwood, an ambitious commodities trader.

As investigators work amid the atmospheric ruins, they discover each woman’s life intersects with the victim beyond their theatrical collaboration. Long-buried secrets, romantic entanglements, financial improprieties, and personal vendettas emerge with each interview.

The ancient fort becomes a psychological battleground where Tremayne must separate performance from reality. Everyone knew the choreography of Caesar’s death, everyone had access to the stage, but only one transformed Shakespeare’s fiction into calculated execution.
