1915. The great detective Sherlock Holmes is retired and quietly engaged in the study of honey bees when a young woman literally stumbles into him on the Sussex Downs. Fifteen years old, gawky, egotistical, and recently orphaned, the young Mary Russell displays an intellect to impress even Sherlock Holmes – and match him wit for wit.
Under his reluctant tutelage, this very modern twentieth-century woman proves a deft protégée and a fitting partner for the Victorian detective. In their first case together, they must track down a kidnapped American senator's daughter and confront a truly cunning adversary – a bomber who has set trip-wires for the sleuths and who will stop at nothing to end their partnership.
