Zainab had read the library book three times before she noticed the handwriting.
It was in the margin of page 112, so faint she had taken it for a smudge. In tiny, slanted letters, someone had written: "Don't trust the narrator." Underneath, in different ink and a rounder hand, someone else had replied: "Why not?" And beneath that, in the first writer's slant: "Read chapter 9 again."
She read chapter 9 again. Then she read it a fourth time, and a fifth, and on the sixth she saw it – a single sentence where the narrator claimed to have been at home when, three chapters earlier, he had described himself on a train. A lie, hidden in plain sight. The whole story tilted, like a picture knocked crooked on a wall.
Zainab sat back. She checked the date stamps on the card inside the front cover. The book had been borrowed forty-seven times since 1994. Somewhere among those forty-seven readers were two people who had held a conversation across years without ever meeting.
She found a pencil. For a long time she hesitated over the page, feeling as if she were about to speak in a room full of strangers. Then, carefully, beneath the other two, she wrote: "Found it. Thank you."
When she returned the book, the librarian frowned at the pencil marks. Zainab apologised. But as she walked home, she wondered who would be next to find them.
