A crime of passion strikes close to home when Gemma and her best friend, Hazel Cavendish, travel to Scotland, a land of mists and fine whiskey, of hidden pasts and dangerous secrets, or so Gemma discovers when an unexpected meeting with Hazel's old flame yields shocking—and mortal—consequences.

Hazel is the logical suspect, but Gemma knows nothing is simple in this place of secrets and long-seething hatreds. As even more damning evidence piles up against the friend Gemma never truly knew, the investigation takes a darker, more sinister turn. Gemma knows she will need assistance to unravel this bloody knot. And so she calls the one man she can trust, Duncan Kincaid, to join her far from home and in harm's way.
