For fans of White Lotus, Benjamin Stevenson, and Anthony Horowitz, a locked-room mystery set in 1960 at an isolated Greek island resort following a group of strangers, a suspicious death, and a washed-up actor ready to put his on-camera detective skills to the test.



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.



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. The final reveal will surprise even the sharpest mystery lover in a truly satisfying conclusion.
