Changi was set like a pearl on the eastern tip of Singapore Island, iridescent under the bowl of tropical skies. It stood on a slight rise and around it was a belt of green, and farther off the green gave way to the blue-green seas and the seas to infinity of horizon.
Closer, Changi lost its beauty and became what it was — an obscene forbidding prison. Cellblocks surrounded by sun-baked courtyards surrounded by towering walls.
Inside the walls, inside the cellblocks, story on story, were cells for two thousand prisoners at capacity. Now, in the cells and in the passageways and in every nook and cranny lived some eight thousand men....
These men too were criminals. Their crime was vast. They had lost a war. And they had lived.
