On his desk the police find newspaper cuttings about a murder case dating from the Second World War, when a young woman was found strangled behind Reykjavík's National Theatre. Konrád, a former detective, is bored with retirement and remembers the crime. He grew up in ?the shadow district', a rough neighborhood bordered by the National Theatre. Why would someone be interested in that crime now? He starts his own unofficial enquiry. Alternating between Konrád's investigation and the original police inquiry, we discover that two girls had been attacked in oddly similar circumstances. Did the police arrest the wrong man? How are these cases linked across the decades? And who is the old man? A deeply compassionate story of old crimes and their consequences, The Shadow District is the first in a thrilling new series of novels by the worldwide bestselling author Arnaldur Indridason.","forthcoming":false,"isbn13":"9781250138170","publication_date":"20180828","publisher":"Picador","slug":"the-shadow-district","subtitle":"A Thriller","title":"The Shadow District"},"discovery":{"categories":{"all":[{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7562,"source":"bisac_hint_model"},{"bisac_code":"FIC022020","confidence_band":"medium","label":"Police Procedurals","score":0.7524,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.7428,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.7562,"source":"bisac_hint_model"},{"bisac_code":"FIC022020","confidence_band":"medium","label":"Police Procedurals","score":0.7524,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.7428,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC022020","confidence_band":"high","label":"Police Procedurals","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"International Crime Fiction","score":0.7562,"slug":"international-crime-fiction"},{"label":"Police Procedurals","score":0.7524,"slug":"police-procedurals"},{"label":"British Mystery","score":0.7428,"slug":"british-mystery"}],"reader_fit":["Good for readers who enjoy International Crime Fiction","Good for fans of Mystery","Good for readers who enjoy International Crime Fiction and Police Procedurals."],"related_lists":[{"intro":"","slug":"shelf-fic022080-international-mystery-crime","title":"International Mystery & Crime Books","url":"https://bookfrontier.com/lists/shelf-fic022080-international-mystery-crime"}],"series":null,"similar_books":[{"authors":["Christoffer Carlsson","Rachel Willson-Broyles"],"book_id":"9780593733059","cover_image_url":"https://img.bookfrontier.com/9780593733059.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.9564,"title":"The Living and the Dead","url":"https://bookfrontier.com/books/9780593733059"},{"authors":["Jørn Lier Horst"],"book_id":"9781668076095","cover_image_url":"https://img.bookfrontier.com/9781668076095.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.9439,"title":"The Cabin","url":"https://bookfrontier.com/books/9781668076095"},{"authors":["Val McDermid"],"book_id":"9780061688997","cover_image_url":"https://img.bookfrontier.com/9780061688997.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.8878,"title":"A Darker Domain","url":"https://bookfrontier.com/books/9780061688997"},{"authors":["Arturo Perez-Reverte","Frances Riddle","Arturo Pérez-Reverte"],"book_id":"9780316594349","cover_image_url":"https://img.bookfrontier.com/9780316594349.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.8847,"title":"The Final Problem","url":"https://bookfrontier.com/books/9780316594349"},{"authors":["Tony Roberts","Stuart Woods","Penguin Audio","& 0 more"],"book_id":"9780451218704","cover_image_url":"https://img.bookfrontier.com/9780451218704.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.843,"title":"Dark Harbor","url":"https://bookfrontier.com/books/9780451218704"},{"authors":["Louise Penny"],"book_id":"9781250328151","cover_image_url":"https://img.bookfrontier.com/9781250328151.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.8387,"title":"The Grey Wolf","url":"https://bookfrontier.com/books/9781250328151"},{"authors":["Tana French"],"book_id":"9780593493458","cover_image_url":"https://img.bookfrontier.com/9780593493458.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.835,"title":"The Hunter","url":"https://bookfrontier.com/books/9780593493458"},{"authors":["Ruth Rendell","Davina Porter","Recorded Books","& 0 more"],"book_id":"9780345341983","cover_image_url":"https://img.bookfrontier.com/9780345341983.jpg?v=20260418T162306Z%3A2026-04-19T10%3A16%3A55Z","score":8.8321,"title":"Death Notes","url":"https://bookfrontier.com/books/9780345341983"}],"topics":[],"what_you_get":["Reading lane: International Crime Fiction and Police Procedurals.","Publisher: Picador."]},"llm_signals":null,"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":false,"similarity_seed":true},"stats":{"amazon_ratings_count":1317,"goodreads_ratings_count":5400,"goodreads_reviews_count":655,"quality_score":0.9655}}
