Reven Lynch's favorite jogging spot, her crime-loving antenna goes up. Though the murder makes Reven and her best friend, Violet Bolton, reconsider their running routine, it also introduces her to the smooth, enigmatic Detective Gunner. Gunner is convinced that the murderer is a society big shot hiding in plain sight. But he is totally out of his element in the rarefied world of embassy dinners and symphony balls, and Reven is perfectly positioned to feed him the inside information he needs. She throws herself into her role as the detective's "ersatz Mata Hari," only to discover that the prominent skirt-chasing businessman for whom she's fallen tops Gunner's shortlist of suspects. And that's not the half of it: a philanthropic bombshell named Cynthia Rinehart has taken the city by storm, and Violet's rock-solid marriage encounters some major turbulence...During the course of the investigation, the social world will unravel, an old friendship will be put to the test, scandalous secrets will be unleashed, and Reven will discover that nothing old or new, in high culture or low life, is what it appears.
