The Librarian found the journal during a routine inventory of the calibration hall's tertiary storage. The journal had been wrapped in grey cloth and shelved inside a reference tome on mineral classification, between the pages at the entry on crystal lattice. The Librarian had been verifying the tome's provenance. She had not been looking for the journal.
She read it in sequence. She read it in reverse. She read it in the order of the entry dates.
The final entry bore a mark in its lower margin. The mark was a single dot crossed by two short lines. The Librarian has not seen the mark in any hand but her own.
She compared the entries to the Order's incident reports. The first entry was dated the day of the senior calibrator's broken crystal. The second entry was dated the day of the oil flame's adjustment. The third entry did not correspond to any incident the Order had filed.
The Librarian searched for the third. She did not find an incident. She found a death. A clerk had been recovered from a maintenance shaft in the condition of the fourteen. Seated. Still. Pulse stopped. She was a woman the acolyte had spoken with three times in the month before. She had been responsible for the calibration hall's material records. Those records have not been filed since.
The clerk's name was in the ledger.
The journal has twenty-seven entries. The Librarian has identified correspondences for four. The others she has not attempted to match.
