Accusations abound in the small, close-knit community, and 'old' religions spar against 'new' while fear runs like wildfire through the streets. With so many potential motives and countless opportunities, there's only one man who can help solve this particular mystery... Murder and mystery are peppered with romance and humour in this fast-paced crime whodunnit, set amidst the spectacular Northumbrian landscape.
