In 2017, the story of Swedish journalist Kim Wall, who was killed onboard a submarine in Copenhagen, shocked millions of readers all over the world – readers who had a hard time reconciling this brutal murder with the image of Denmark as one of the world’s safest and happiest countries.

Deep Water begins the moment Kim Wall is reported missing and follows the case as it changes from sea rescue mission to murder investigation, and as the Danish authorities realize that the famous submarine owner is a different person to the one represented in the media.

The book is based on interviews with people who were involved in the search for Kim Wall and the investigation of her murder, as well as first-hand witnesses from the case, most of whom had not talked to the media before. Together, their testimonies tell a story of how a historic collaboration succeeded in finding Kim Wall’s remains, imposed the country’s harshest punishment on her murderer, and restored order in a society long characterized by trust.
