Karen, recently divorced, returns to her childhood home in Nova Scotia after her mother’s death, to care for her developmentally-disabled sister. Karen is understandably over-whelmed with grief and the difficult care of her sister. Thus she gratefully accepts extra assistance from Trevor, one of her sisters care-givers. So she is susceptible to manipulation and Trevor is a master manipulator. Accordingly, this is a masterful and entirely creepy character study of human frailty.
Simply put, this is a fantastic read. The place is contemporary Halifax with three main characters: an ER nurse, a policeman, and a 911 dispatcher. Their lives intersect but obliquely, in a fashion that is never contrived. The backstory lives are complicated, of course, but realistically so. The best part of the book is the feeling of the stories – stress exacerbated by heat and overwork. By the way, the title refers to the overnight hours of 3-6am when emergency activities are temporarily quiet. Just excellent story-telling.
