London, 1878. Charles Lenox's detective agency is rapidly expanding, and he has all the work he can handle. But in this 14th outing (after The Last Passenger), when Prime Minister Benjamin Disraeli offers him a diplomatic mission for the Queen, Lenox welcomes the chance to travel to America. Arriving in New York, Lenox enters high society, but the festivities are ruined by the death of the season's most beautiful debutante, who appears to have thrown herself from a cliff. Or was it murder? Lenox's reputation has preceded him to the States, and when he is summoned to a magnificent Newport mansion, what ensues is a fiendish game of cat and mouse.
