Book excerpt: Helene Tursten's explosive new series features Detective Inspector Embla Nyström, a sharp, unforgiving woman working in a man's world. When one of her peers is murdered during a routine hunting trip, Embla must track down the killer while confronting a dark incident from her past. Twenty-eight-year-old Embla Nyström has been plagued by chronic nightmares and racing thoughts ever since she can remember. She has learned to channel most of her anxious energy into her position as Detective Inspector in the mobile unit in Gothenburg, Sweden, and into sports. A talented hunter and prizewinning Nordic welterweight, she is glad to be taking a vacation from her high-stress job to attend the annual moose hunt with her family and friends. But when Embla arrives at her uncle’s cabin in rural Dalsland, she sees an unfamiliar face has joined the group: Peter, enigmatic, attractive, and newly divorced. And she isn’t the only one to notice. One longtime member of the hunt doesn’t welcome the presence of an outsider and is quick to point out that with Peter, the group’s number reaches thirteen, a bad omen for the week. Sure enough, a string of unsettling incidents follow, culminating in the disappearance of two hunters. Embla takes charge of the search, and they soon find one of the missing men floating facedown in the nearby lake. With the help of local reinforcements, Embla delves into the dark pasts of her fellow hunters in search of a killer.
