The codebooks are stacked inside as neatly as gold bars. They are wet and mildewed and their front covers are all missing, but this is mint condition by the standards of wartime. Stripped to the waist and streaming with sweat, the men raise the books out one by one, like nurses lifting newborn infants from the bassinette, and carry them to tables where they slice away the rotten bindings and peel the sodden pages off the stacks one by one, hanging them from improvised clotheslines strung overhead. The stench and damp of New Guinea saturate the air as the river water trapped in those pages is lifted out by the rushing air; it all vents to the outside eventually, and half a mile downwind, pedestrians wrinkle their noses. The whorehouse’s closets—still redolent of French perfume, powder, hairspray and jism, but now packed to the ceiling with office supplies—are raided for more string. The web of clotheslines grows, new layers crisscrossing above and below the old ones, every inch of string claimed by a wet page as soon as it is stretched. Each page is a grid, a table with hiragana or katakana or kanji in one box, a group of digits or Romanji in another box, and the pages all cross-referenced to other pages in a scheme only a cryptographer could love.
