There are a lot of books written about the adventures of Sherlock Holmes. Laurie R. King has a series of books about Mary Russell who met Sherlock when he had retired. She is a lot younger but that didn’t stop them from falling in love. Mary is very smart and has some of the same deductive talents that Sherlock has. This book is a continuation of a story in the book “The Language of Bees”. When Sherlock retires he takes up bee keeping as a hobby and so they use this reference when sending messages to each other by newspaper ads. At the start of this story Mary is on the run with her granddaughter Estelle after she rescues her from a religious fanatic who is after Sherlock. Sherlock is on the run with his son Damien who is accused of murdering his wife. I suggest reading “The Language of Bees” first so all of this makes sense. Laurie R. King was written 12 Mary Russell books and I would also suggest reading the first, “The Beekeepers Apprentice”, when she introduces Mary Russell. If you are a Sherlock Holmes fan you won’t be disappointed.
