Prison life is hard for Curzon and all of the other Patriot soldiers in there. The British do not do much of anything to ensure that the prisoners are taken care of. The place is not clean, so disease runs rampant. Conditions are freezing, and food is very scarce. Curzon enters the prison already wounded, and his condition worsens as he spends more time in the prison. Isabel first sees Curzon in prison in chapter 35. She plans to bring him some food, and she is shocked by his abysmal appearance. Some soldiers step aside, and she sees "a bundle of rags" on the floor and realizes that the bundle of rags is Curzon. He is freezing cold and can't stop shaking, and there is no blanket to cover him. His lips are dry and cracked, and his leg is still covered in the bloody bandage that was initially put on his combat wound.
Chapter 36 begins, and readers are told that people donated blankets to the prison, so things are supposedly better; however, Isabel is shocked to see piles of dead bodies stacked up waiting to be buried. Curzon is not doing well. He's feverish and unwilling to talk. By chapter 37, he's even worse. He is shaking so badly that he can barely stand, and he is incapable of answering Isabel. He doesn't know who he is or where he is. He's completely delirious and coughing so hard Isabel fears his ribs will break. He is dying, and Isabel knows it. This is one reason why she puts herself at risk to save him.
