Unlike many historical mysteries, this is based on a real person (Kate Warne) and successfully balances genuine historical gravity with the 'fun' of a detective caper.
In 1859, eleven-year-old Nell Warne is sent to live with her aunt, Kate Warne, who happens to be the first female operative for the Pinkerton Detective Agency. Nell is a 'grief-stricken orphan' but quickly proves her value through her powers of observation and ability to go undercover.

Parallel to the historical stakes is Nell's personal quest to uncover the truth about her father's death and her brother's disappearance.
