Unholy Rites - Kay Stewart

The third book in the "Danutia Dranchuk Mystery" series reunites RCMP constable Danutia Dranchuk with her friend, drama critic Arthur Fairweather in England when Arthur returns to the Peak District to attend his mother's funeral. Suspecting foul play in her death, Danutia and Arthur question the feuding members of the village's well dressing committee. They soon discover that the practice of ancient Celtic rituals persists and has evolved into a dangerous and deadly ceremony. In a region with chilling reminders of child labour during the Industrial Revolution, Danutia must navigate a community with a complex and layered history. And, her personal and professional boundaries become blurred. When a child from the village is abducted, the race to save him leads Arthur into extreme danger. Only Danutia has a chance of rescuing both Arthur and the child from an "unholy rite".
