A clandestine operation unfolds in Paris as a team is assembled to surveil Princess Diana and her lover during their August 1997 visit. The operation, orchestrated by an international fixer, involves Branch man John Harper, Ritz hotel deputy director of security Henri Paul, and paparazzo James Andanson, who are tasked with monitoring the Princess. However, they are not the only ones with their eyes on Diana, introducing an element of unknown threat and competing interests into the surveillance.

The premise of a covert operation shadowing Princess Diana in the days leading up to her tragic death in Paris suggests a tense, suspenseful thriller. The focus on surveillance targets and the hint of other unknown watchers points to a narrative rich in intrigue and potential betrayal. The historical setting and the real-life figures involved lend a layer of gravity and speculative fiction to the story. The author's approach likely aims to weave a fictionalized account of conspiracy and hidden motives surrounding a pivotal historical moment.
