Ex-police detective Michael McLaren is determined to have a peaceful holiday after the fiasco of his first attempt at Windermere, so he stops at a bed-and-breakfast in Moorton, a village in Cumbria. But mystery and murder seek him out, and he soon succumbs to the B&B owner's plea to investigate the year-old death of her daughter's fiancé, a young musician.

The Lake District parish seems peaceful, but a rival musician's jealousy and a business partner's anger boil beneath the façade. Mix that with 'Barmy Barry's' sightings of fairy lights at the castle, references to Uther Pendragon's return and the secrets in the woods, and McLaren finds his sanity shaky.

When the vicar is attacked and Barry disappears, McLaren sets a trap for the killer. But as it plays out, his concern shifts from the potential capture to praying he and his friend can escape with their lives.
