The year is 1904. Twenty-three-year-old Jemima Pitt, the daughter of Thomas Pitt, head of Britain’s Special Branch, is crossing the Atlantic. She is traveling with an acquaintance, Delphinia Cardew, who is to marry the aristocratic Brent Albright in a high-society New York wedding-a grand affair that will join together two fabulously wealthy families, titans of the international financial world. But Jemima senses a mysterious shadow darkening the occasion. Missing from the festivities is Delphinia’s mother, Maria, who is marked by disgrace. Nearly sixteen years ago, Maria abandoned young Delphinia and disappeared-and now the Albrights refuse to mention her name. But when Harley, the groom’s charismatic brother, asks Jemima to help him search for Maria and forestall the scandal that would surely follow if the prodigal parent turned up at the wedding, she agrees to assist him. From Hell’s Kitchen to Fifth Avenue, the Lower East Side to Central Park, Jemima trudges through strange, snowy streets, asking questions but getting few answers-and never suspecting that she is walking into mortal danger, from which not even a handsome young police officer named Patrick Flannery may be able to protect her.
