Nadia Ravenwood, the estranged daughter of a Russian spy, delves into the dark heart of 1927 New York City as a secret fixer for the rich and famous. Her associate, Stephen Locke, a World War I veteran, narrates this action-packed mix of mystery and thriller. When a Socialite is framed for murder, Nadia is thrust into a case that takes her from the opium dens of the Bowery slums to luxury hotels and a millionaire's yacht in search of the real killer. Hounded by her client's family patriarch and the police, she's thwarted at every turn as alternate suspects end up dead. In the process, she gets entangled in the dangerous underworld of drug dealers, gun runners, and anarchists involved in a conspiracy orchestrated by her notorious father, Nicholas Ravenwood, which will have world-shaking consequences if she fails to foil his plans.
