底下摘錄小說裡的一個段落 (David手癢自己試譯,僅供大家參考)
驗屍間裡我和她的屍體獨處了幾分鐘。我覺得情緒失控，整個人魂不守舍。在我意識到自己在做什麼之前，我發現我屈身在她的耳旁，把所有的真象告訴了她。她就躺在那裡，話語像是有自己的意識般的從我嘴裡傾洩而出。她溼掉的長髮從鋼製解剖床的床緣垂了下來。她的雙眼如玻璃球般直瞪著天花板。她連死了看起來都還是如此美麗。

那個早晨，在白亮的驗屍間裡我們的秘密糾葛不清。我站在她的身旁，腳跟站立不安。我重新想起來我如何深深捲入她的生活，她的死如何徹底的毀滅我。我看了羅絲最後一眼，然後深呼吸了一口氣，做好讓她將我帶到她的世界的準備，我越跌越深，直到我整個人完全沉入罪惡深淵之中。

There had been a few minutes when I was alone with her in the autopsy room. I'd felt wild. Absent. Before I could stop myself I was leaning close to her, telling her everything. The words draining out of me as she lay there. Her long damp hair hanging off the back of the steel table. Glassy eyes fixed blindly on the ceiling. She was still so beautiful, even in death.

Our secrets circled madly around the bright white room that morning. Rocking back and forth on my heels as I stood there next to her, I knew how far in I was again, how comprehensively her death could undo me. I looked at Rosalind Ryan properly for the last time before breathing deeply, readying myself, letting her pull me back into her world, and I sank down, further and further until I was completely, utterly under.
