In 1924, San Francisco is booming. The great fire and earthquake of 1906 cleared the ground for a modern city, but the closer she comes to the place she used to call home, the more troubling Mary Russell's dreams become... As Russell and her husband, the eminent Sherlock Holmes, attempt to settle their affairs in the City by the Bay, Mary's past isn't the only thing that catches up with them - a mysterious stranger is waiting for the pair, and may be the only one who holds the key to the locked rooms that have been haunting Mary's dreams...

In Locked Rooms, internationally bestselling author Laurie R King portrays the 1920s in exuberant detail and, with near-lyrical prose, presents a compelling murder mystery that will keep your imagination and attention locked in its pages until the very end.
