Handsome, intelligent, street-smart, ruthlessly ambitious, and omnisexual, young Addison Grimmins has been hired by the Lord Exchequer of England to be his second and to do what Lord R. cannot do himself. After a country estate wedding, the Marchioness of R. is discovered missing. Is it a kidnapping or…a more sinister plot? Addison vows to find her and bring her back no matter what it takes. It is the 1880s and despite only letters, bribed information, and telegrams as communication; despite only horse, coach, and train service as transportation, Addison tracks Lady R. across Europe, via the strangest people and places: from Venetian palaces to opium dens. Who and what he discovers about her, and more fatefully about his own life, will lead Addison to the crisis of his life, an extraordinary decision, and a stiletto duel with his most implacable foe.
