Perfect for fans of Knives Out, Benjamin Stevenson, and Anthony Horowitz. \"Perfect. . . Like taking a warm bath in the best of the Golden Age.\"― Janice Hallett June, 1960. Rough weather at sea leaves a group of strangers stranded on the idyllic Greek island of Utakos, all guests of the only local hotel. Nothing could prepare them for what happens next: Edith Mander, a quiet British tourist, is found dead inside a beach cabana. What appears at first glance to be a clear suicide reveals possible signs of foul play to Ormond Basil, an out-of-work but still well-known actor who in his glory days portrayed the most celebrated detective of all time. Accustomed to seeing him display Sherlock Holmes’ amazing powers of deduction on the big screen, the other guests believe that the actor is the best equipped to uncover the truth. But when a second body is discovered, there is not a doubt in Basil’s mind: a murderer walks among them. What’s more, the killer is staging each crime as a performance, leaving complex clues that bear an eerie resemblance to those found in the pages of Conan Doyle stories. This is a criminal who knows every trick in the book and is playing a deadly literary game. As the storm rages, Basil must become the genius detective he has only pretended to be. This clever, whip-smart, locked-room mystery from internationally bestselling author Arturo Pérez-Reverte is a love letter to golden-age detective novels. The Final Problem delights in exploring the tension between an investigator and his suspects, as well as a writer and his reader, delivering a revelatory twist that will shock even the sharpest of mystery fans.","forthcoming":false,"isbn13":"9780316594349","publication_date":"20260210","publisher":"Little, Brown and Company","slug":"the-final-problem","subtitle":"A Novel","title":"The Final Problem"},"discovery":{"categories":{"all":[{"bisac_code":"FIC022140","confidence_band":"medium","label":"Cozy Holiday Mysteries","score":0.8372,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.8157,"source":"bisac_hint_model"},{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.8051,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC022140","confidence_band":"medium","label":"Cozy Holiday Mysteries","score":0.8372,"source":"bisac_hint_model"},{"bisac_code":"FIC022030","confidence_band":"medium","label":"British Mystery","score":0.8157,"source":"bisac_hint_model"},{"bisac_code":"FIC022080","confidence_band":"medium","label":"International Crime Fiction","score":0.8051,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC022060","confidence_band":"high","label":"Historical Mystery","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC022140","confidence_band":"high","label":"Cozy Holiday Mysteries","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC050000","confidence_band":"high","label":"Crime Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Cozy Holiday Mysteries","score":0.8372,"slug":"cozy-holiday-mysteries"},{"label":"British Mystery","score":0.8157,"slug":"british-mystery"},{"label":"International Crime Fiction","score":0.8051,"slug":"international-crime-fiction"}],"reader_fit":["Good for readers who enjoy Cozy Holiday Mysteries","Good for readers interested in crime","Good for fans of Mystery"],"related_lists":[{"intro":"","slug":"shelf-fic022080-international-mystery-crime","title":"International Mystery & Crime Books","url":"https://bookfrontier.com/lists/shelf-fic022080-international-mystery-crime"},{"intro":"","slug":"shelf-fic022030-traditional-british","title":"Traditional British Books","url":"https://bookfrontier.com/lists/shelf-fic022030-traditional-british"}],"series":null,"similar_books":[{"authors":["Edgar Wallace"],"book_id":"9781952438714","cover_image_url":"https://img.bookfrontier.com/9781952438714.jpg?v=20260407T080002Z-pairingsrefresh%3A2026-04-07T08%3A00%3A02Z","score":18.4784,"title":"The Dark Eyes of London","url":"https://bookfrontier.com/books/9781952438714"},{"authors":["Agatha Christie"],"book_id":"9781952438455","cover_image_url":"https://img.bookfrontier.com/9781952438455.jpg?v=20260407T080002Z-pairingsrefresh%3A2026-04-07T08%3A00%3A02Z","score":16.1863,"title":"The Murder on the Links","url":"https://bookfrontier.com/books/9781952438455"},{"authors":["Mark Pryor"],"book_id":"9781645060307","cover_image_url":"https://img.bookfrontier.com/9781645060307.jpg?v=20260407T080002Z-pairingsrefresh%3A2026-04-07T08%3A00%3A02Z","score":16.1787,"title":"The French Widow","url":"https://bookfrontier.com/books/9781645060307"},{"authors":["Ruth Rendell","Davina Porter","Recorded Books","& 0 more"],"book_id":"9780345341983","cover_image_url":"https://img.bookfrontier.com/9780345341983.jpg?v=20260407T080002Z-pairingsrefresh%3A2026-04-07T08%3A00%3A02Z","score":16.1548,"title":"Death Notes","url":"https://bookfrontier.com/books/9780345341983"},{"authors":["A.E.W.
