Chapter 1 — A Space Between Numbers
At nine on Monday morning, Leena Sen found a space where a piece of paper should have been.
The space was unremarkable. It lay between two grey folders in a box that smelled faintly of cardboard and the cool cupboard in which it had spent the weekend. A handwritten list on the inside of the lid ran from C1 to C24. Folder C16 contained a receipt for framing. Folder C18 held a letter about insurance. There was no C17.
Leena checked the list again. Then she checked the table, the empty trolley and the shelf from which she had taken the box. She did not rearrange the other folders. In her five months at the Bellwether Archive, she had learned that putting something where it seemed to belong could make it harder to discover where it had actually been.
Through the reading-room window, the harbour lay flat and pewter-coloured beneath the morning sky. A delivery driver wheeled crates into the café opposite. On the pavement, someone had tied a yellow ribbon around a bicycle basket. Nothing outside suggested that this would be a difficult day.
Helen Ward came in carrying a stack of clean supports for the exhibition books.
“You look as though the building has asked you a question,” she said.
“It has. Where is C17?”
Helen put the supports down. She was the archive’s senior assistant, though she had worked there longer than anyone with a grander title. Her spectacles hung from a green cord. She never pushed them onto her head; Leena had noticed that during her first week and, for reasons she could not explain, trusted her more because of it.
“The catalogue sheet?” Helen asked.
“That is what the list says.”
“It was here on Friday.”
Leena looked up. “You saw it?”
“I checked the box before it went back. Friday, half past four. One sheet in a folder. Brown edge, fold at the bottom.”
“Was anyone using it?”
“Everyone has been using everything. The exhibition opens on Thursday.”
