Charlie James is chasing her first big scoop as correspondent for British-based newspaper The Times, and she needs to prove to her boss that she can do this job as well, if not better, than her male counterparts. The best way to forge the necessary contacts quickly is to make well-connected British expats, Lord and Lady Ashworth, her business. Lady Eleanor knows everyone in Parisian high society, and at her sumptuously extravagant annual party, a Circus Ball, Charlie will meet them all.

On the summer solstice eve, the Circus Ball is in full swing, with the Parisian elites entranced by burlesque dancers, tightrope walkers, a jazz band . . . and a horrific murder. A wealthy but unscrupulous investor is dead, and the list of suspects is a veritable who's who of le haut monde. As Charlie tries to determine who the murderer is, she finds herself drawn into the magical parties, couture houses, and bohemian wine bars of the City of Lights. Soon secrets start to unravel, including some Charlie has a personal stake in keeping hidden.
