The Beekeeper’s Apprentice by Laurie R. King (1994)
In the first entry in Laurie R. King's series featuring Mary Russell and Sherlock Homes, the reader is introduced to 15-year-old Mary as she encounters the retired Sherlock at his country home where he tends to his honeybee hives. Sherlock is amazed at the intelligence of this young girl and soon brings her in as an apprentice for disguise and deduction. Soon the game is afoot as the two work together to find a kidnapped daughter of an American senator and then encounter a descendant of an old foe eager for revenge.
Start with The Beekeeper's Apprentice, and check back later this month for my review of the latest entry in the series.
