You could have saved her.

Sure as the tide against his Highland shores, the refrain beats into Constable Angus 'Dubh' MacNeil's mind. For years it has haunted him, accompanied by the faces of those he could not save-the Burned Man, the Strangled Woman, the Drowned Boy. All witnesses to a secret he cannot share and a gift he now refuses to embrace.

You could have saved her. The refrain drives Angus to the seashore at dawn, where a girl lies on the unblemished sand. She wears a green cloak and cradles a corps creadha, a Highland voodoo doll. She has suffered a ritualistic, three-fold death-her head bludgeoned, her throat cut, and symbolically drowned.

It is Faye Chichester, daughter of an American billionaire whose mission to reintroduce wolves to the Highlands has embroiled the village of Glenruig. But even as media and police swarm the area, that refrain-you could have saved her-echoes in all Angus's thoughts. For he carries a burden, a blessing, a curse, a secret-da-shealladh, the second sight of Gaelic lore.

Gills MacMurdo, noted folklorist, academic, and Angus's oldest friend, confirms what the da-shealladh is warning. Just as Faye's death was three-fold, so must the murder victims fulfil the ancient pattern. More will die, unless Angus does what he must-close his eyes and see.
