The Beekeeper's Apprentice

In 1915, a retired Sherlock Holmes spends his days studying honeybees in Sussex until he literally trips over Mary Russell, a brilliant and sharp-tongued fifteen-year-old orphan. Recognizing a mind that matches his own, Holmes takes her on as a student, training her in the arts of deduction and disguise. Their quiet life of scholarship is interrupted when they are pulled into a high-stakes kidnapping case that threatens to expose secrets from Holmes's own past.
