On Halloween Day, 1968, weekend sailor and lifelong tinkerer Donald Crowhurst set sail aboard an untested trimaran, The Teignmouth Electron, determined to win the first-ever official race to single-handedly circumnavigate the globe. At stake was a generous cash prize that would save his failing business and provide an opportunity to very publicly prove the value of the Navicator, the handheld marine navigation device he had invented and manufactured. The race was sponsored by the Sunday Times, and the victor would get not just money but invaluable media exposure. Even before the race began, things looked uncertain for Crowhurst. The boat he was sailing was of a completely new design, as yet unproven; one observer noted that the boat was very fast but that it couldn't sail close to the wind. When it was running at full speed it began to vibrate, shaking loose the screws in the self-steering apparatus. Ironically, even Crowhurst's navigational abilities were questioned during a pre-race test sail. Worst of all, there wasn't time to add in all the usual safety features. Undeterred, Crowhurst just beat the October 31 deadline for departure and headed into open water. Soon after the race began, Crowhurst ran into trouble, sailing far more slowly than he had planned. He realized that he had no chance of winning the race whatsoever, and instead faced a difficult choice: finish the race and risk his life aboard a boat he couldn't control; give up in defeat and send his business into bankruptcy; or take a shortcut and falsify his navigational logs. Fatefully, Crowhurst chose the latter, maintaining two logs from that moment on'one actual and one invented. Pieced together by two Times reporters following the discovery of the abandoned Teignmouth Electron (and Crowhurst's navigational logs), The Mercy captures the enigma at the center of Crowhurst's final voyage'a quixotic attempt to save his business and provide for his young family by attempting to become the first person to sail around the world without stopping. It is a mesmerizing journey into uncharted territory, not just of the world's oceans but of the darkest corners of the human mind.

本作は単なる海洋冒険の失敗譚ではありません。一人の男が名誉と現実の狭間で引き裂かれ、自己崩壊していく過程を克明に追った、極上の精神的スリラーです。著者は、彼が遺した二つの航海日誌という狂気の証拠を鮮やかに分析しました。嘘が嘘を呼び、孤独な海上で自己という輪郭が溶けていく描写は、文学的にも比類なき凄みを放っています。 本書の白眉は、航海日誌という無機質な記録が、次第に絶望的な告白へと変貌する過程にあります。現実と虚構が混ざり合い、座標を失うとともに精神の均衡も崩れていく様は、深淵を覗き込むような恐怖を誘います。これは単なる記録文学を超え、成功への執着と人間性の剥離を鋭く問う、普遍的な悲劇なのです。
