Murder and mystery in a Scottish castle...

When Alice Beckingham boards a train for Edinburgh in 1929, she begins a journey that will test everything she thinks she knows about her past and her family. From the moment of her arrival at the rugged and remote Druiminn Castle, something sinister haunts her steps.

With the murder of her host and the revelation that one of her fellow guests at the castle is an unscrupulous jewel thief, Alice resolves to uncover secrets that someone will stop at nothing to keep hidden.

Coercing the coolly unpredictable Sherborne Sharp into assisting her, Alice follows in the footsteps of her detective cousin Rose and pursues a heartless killer through glittering dining rooms, shadowed passages, and moonlit groves. A mysterious local legend may hold the key to unraveling everything, but will Alice survive long enough to decipher it?
