Still reeling from the dangers of a recent case, forensic genealogist RaeJean Hunter takes on a supposedly routine case to locate the missing heir of a woman she met in Central Park a year ago. Tantalized by a hefty income, she accepts.

But there's a catch?she must find the heir within six months or the forty-million-dollar estate is donated to a local university.

With the tight deadline comes the chance of a sizeable bonus, a series of unforeseen obstacles, and the unexpected connection to a cold case from 1910, when perfume heiress Dorothy Arnold disappeared without a trace.

Armed with only her genealogical skills, the books and historical documents she unearths, and an antique doll that seems to be guiding her toward the answers she needs, RaeJean faces dangerous events that threaten to shatter her world and challenge her to meet the deadline. Her travels throughout the United States and New Zealand in search of answers bring with it its own question: Will she find the heir before time runs out?

But someone doesn't want her to solve the case. The clock is ticking, and it will take every ounce of grit RaeJean has to solve this mystery and outwit the dangers that threaten her present while she sifts through the past.
