There's blood in the heather & a murderer on the loose when Gently pays a quite visit to the Highlands of Scotl&. Had Brenda Merryn not been such a strong-willed woman & had she not been so much in love with George Gently driving all the way to Scotland for a holiday with Gently's sister & brother-in-law might have been a bit of a challenge. Spying on a heavily armed private army of nationalists being held at gunpoint on the hillside being held prisoner in a filthy outhouse & becoming involved in a murder would be unthinkable. For Gently it's all in a day's work & his holiday is put on hold while he stalks a murderer in the mountains with Brenda by his side.
