The Wolf and the Stone
Edie begins to realise that there are unusual numbers of foreigners taking an interest in the geology of Craig Island, north of the Arctic Circle.
She's also increasingly sure of a link between her stepson's apparent suicide and the murder of the two southern tourists. Then, she comes across a mysterious stone which might be the key to everything.
