Jaz has moved from Bristol to be with her recently widowed brother; she is a teacher and she has moved from a high-flying head of faculty post in a top school to take a lowly temporary position in a challenging school in the north of England. She is up to the challenge, but she does not expect to find her life is in danger from a man who has already butchered three women; she has met the love of her life, but is he, could he possibly be, the murderer? She discovers some brutal truths about her beloved brother, he seems on the verge of a breakdown, convinced there is a conspiracy surrounding his wife’s death… but where does he go on Fridays, and what does he do? “I was alone, utterly alone. I thought I’d been brave running away from my life in Bristol, my friends and familiar places; I was pleased to be so daring and impetuous, and so certain of my love for David when our eyes had met in the Lees Spa Hotel. But I hadn’t taken him home and made love to him in order to enter a violent world of fear and hate and danger.”
