About the book
Mary Russell is faced with a test of her allegiances when her long-lost uncle reappears—and brings with him a case that even Sherlock Holmes couldn't crack.
When Mary Russell was young, she idolized her wayward Uncle Jake. However, after years of silence, she assumed his troubled ways had led to his demise—until he shows up at her door in Sussex. Jake has returned, burdening his clever niece with a host of troubles. Among them is the scandal that caused their family to shun him: his alleged involvement in the infamous theft of the Irish Crown Jewels from an impenetrable safe in Dublin Castle.
This theft not only rocked a nation, infuriated a king, and shook the English establishment, but also stumped both the Dublin police and Scotland Yard, as well as Sherlock Holmes himself. Yet now, Jake expects Russell to dive right into the middle of it all? To sneak off with him, keeping Holmes in the dark? Despite the implications that the unsolved and scandalous theft might have also involved Mycroft Holmes?
Of course, she cannot comply. Choosing her uncle's side, even temporarily, would pit her against her partner-husband and his secretive and influential brother. She must refuse Jake's request.
On the other hand, this is Jake—the younger brother of her father, her childhood idol, the cherished survivor of a dwindling family.
With conflicting loyalties and hidden international truths, bold falsehoods and carefree deceptions, it seems like another intriguing case for Mary Russell and Sherlock Holmes.
