Dreaming Spies (Mary Russell and Sherlock Holmes, #13)

After an investigation in India. Mary Russell and Sherlock Holmes are on their way to California to deal with some family business. Along the way, they plan to break up the long voyage with a sojourn in southern Japan.

Aboard the ship, intrigue stirs almost immediately. Holmes recognizes the famous clubman, the Earl of Darley. And then there’s the lithe, surprisingly fluent young Japanese woman who befriends Russell and quotes haiku. She agrees to tutor the couple in Japanese language and customs, but Russell can’t shake the feeling that Haruki Sato is not who she claims to be.

Once in Japan, Russell’s suspicions are confirmed in a most surprising way. From the glorious city of Tokyo to the cavernous library at Oxford, Russell and Holmes race to solve a mystery involving international extortion, espionage, and the shocking secrets that, if revealed, could spark revolution—and topple an empire.
