Since the last book Mary and Holmes’ have married. While Holmes goes on his own undercover mission to find out more about Miss Rushkin’s estranged sister.

In this case, going undercover alone to gain the trust of a possibly dangerous suspect, Colonel Edwards: the last person known to have seen and spoken to Miss Rushkin. Now Mary is a strong, brave, intelligent grown woman, who is now an equal to the great Sherlock Holmes’ as she takes on a key role in their investigations. So much has changed since we first met lonely 15-year-old Mary, that sunny day in 1915.

which, if authentic, could whip up a storm of biblical proportions! Then, just days later, Mary and Holmes discover their friend has been tragically killed in a car accident, but was it really an accident?! Who leaves in Mary’s care an ancient manuscript that seems to suggest Mary Magdalene was an Apostle of Jesus…. When they are visited by an old friend, Miss Dorothy Rushkin, an archaeologist just returned from Palestine.

Mary with her books and translations, and Holmes with his newspaper, pipe and bees. It is 1923 and Mary Russell and her husband, the retired Sherlock Holmes, have settled into a comfortable, if slightly dull, routine on their Sussex estate. Earlier this year, I read the second book, A Monstrous Regiment of Women and then with the cooler weather and darker nights in October, it seemed the perfect time to pick up the third book, A Letter of Mary. King’s Mary Russell and Sherlock Holmes mysteries. But why was she murdered? Was it her involvement in the volatile politics of the Holy Land? Was it her championing of women's rights? Or was it the scroll-a deeply troubling letter that could prove to be a Biblical bombshell? In either case, Russell and Holmes soon find that solving her murder may be murder itself.Since reading The Beekeeper’s Apprentice, I have managed to collect much of Laurie R. Clearly there was more to Miss Ruskin than met the eye. But when Miss Ruskin is killed in a traffic accident, Russell and Holmes find themselves on the trail of a fiendishly clever murderer. Miss Ruskin wants Russell to safeguard the letter. Working in the Holy Land, she has unearthed a tattered roll of papyrus with a message from Mary Magdalene. Interrupting the idyllic scene, amateur archaeologist Miss Dorothy Ruskin visits with a startling puzzle. Late in the summer of 1923, Mary Russell Holmes and her husband, the illustrious Sherlock Holmes, are ensconced in their home on the Sussex Downs, giving themselves over to their studies: Russell to her theology, and Holmes to his malodorous chemical experiments.
