Book excerpt: 'Jung-Myung Lee's extraordinary The Investigation, translated by Chi-Young Kim, is set in a period of Korean history that isn't widely known in the West . . . a heart-wrenching novel with many unexpected twists.' – Sunday Times Longlisted for the Independent Foreign Fiction Prize Fukuoka Prison, 1944. Beyond the prison walls the war rages; inside a man is found brutally murdered. Yuichi Watanabe, a young guard with a passion for reading, is ordered to investigate. The victim, Sugiyama – also a guard – was feared and despised throughout the prison and inquiries have barely begun when a powerful inmate confesses. But Watanabe is unconvinced; and as he interrogates both the suspect and Yun Dong-ju, a talented Korean poet, he begins to realize that the fearsome guard was not all he appeared to be . . . As Watanabe unravels Sugiyama's final months, he begins to discover what is really going on inside this dark and violent institution, which few inmates survive: a man who will stop at nothing to dig his way to freedom; a governor whose greed knows no limits; a little girl whose kite finds her an unlikely friend. And Yun Dong-ju – the poet whose works hold such beauty they can break the hardest of hearts. As the war moves towards its devastating close and bombs rain down upon the prison, Watanabe realizes that he must find a way to protect Yun Dong-ju, no matter what it takes. This decision will lead the young guard back to the investigation – where he will discover a devastating truth . . . At once a captivating mystery and an epic lament for lost freedom and humanity in the darkest of times, The Investigation – inspired by a true story – is a sweeping, gripping tale perfect for fans of The Shadow of the Wind. 'It's a thriller, and a war story, and so much more besides. I tore through the last 100 pages, my heart literally racing at times. An intense, captivating achievement, inspired by reality.' - Matt Haig, author of The Midnight Library
