'What You Do Not Know is suspenseful from the very first page' - Dagens Bok Sweden A billion-dollar report. A community at war. A disappearance that was no accident. The late summer heat on Gotland is stifling, but the tension in the village of Åminne is at its breaking point. A series of brazen cottage burglaries has escalated into a lethal explosion, shattering the peace just as Detective Inspector Maria Wern moves into her new summer home. But the fire is only a distraction for a much larger crime. The next morning, Sofi Hartman-daughter of Police Chief Tomas Hartman-vanishes from a desolate stretch of beach. Sofi is no ordinary witness; she is a high-level consultant for Region Gotland, and her upcoming report on controversial oil drilling could make or break billions in venture capital. Both radical environmentalists and ruthless oil tycoons have been waiting for her to speak. Now, someone has ensured she stays silent. While the island erupts in protests led by Sofi's former lover, Tomas Hartman begins a desperate, off-the-books race to find his daughter. He knows the danger Sofi was in-stalked by a predator posing as a journalist and fighting her own internal demons-and he knows that every hour she is missing brings her closer to a permanent silence. As Maria Wern investigates a brutal stabbing on the beach that hits dangerously close to home, she realizes the burglaries, the oil industry, and Sofi's disappearance are all threads in the same deadly web. In this explosive eighteenth installment of the Maria Wern series, international bestseller Anna Jansson proves that what you do not know can't just hurt you-it can bury you. 'Anna Jansson is undeniably a great storyteller.... What You Do Not Know is definitely one of her best detective stories.' - Litteratur Magazinet
