Mamsell Maria Lovisa Laurell is found brutally murdered in her flat in Stockholm in September 1867. An extraordinary investigation follows, with coercive interrogation techniques and unexpected twists. With the help of archived material, court records and coroner Eva Rudd, history professor Roddy Nilsson and prison historian Katarina Kallings, David Lagerkrantz breathes new life into an old criminal case.
