The western maintenance store had kept the missing page because it recorded a debt.
Not because someone had foreseen a future inquiry. Not because the store keeper’s ancestors had spent six centuries guarding a perfect explanation. A supplier had claimed payment for issued parts, a station had disputed the number and the store had preserved both sides rather than lose its own account in the quarrel.
Iven stood beneath a low beam while Indar Kell opened the narrow book.
The store keeper had asked who would copy the material, where the copies would go and whether the original would leave his room. Iven had answered each question before touching a page.
