A routing slip stamped on a Saturday the office was closed, marked with the most beloved stain in investigative work. The building log has exactly one badge entry that day.
This is week twelve of the 2026 Clutch Blanket Mystery: a free 8 inch coffee ring square, a parchment document base with a single caramel ring sewn deliberately imperfect, plus chapter twelve of The Harlow County File. No chart, no colorwork; the whole design is one cord on a plain base. The square finishes with the same 140 stitch joining round as every other week.
The fastest build since Week 03: a plain parchment base and one sewn caramel cord, laid in an intentionally imperfect circle.
The ring’s cord is computed for a 4.5 inch circle, ch 64 plus a 3 chain overlap so the ends cross the way a real cup mark does.
The base departs from navy on purpose; a coffee ring lives on paper, so this square is the document itself.
Same 140 stitch joining round as every week before it, worked in navy to keep the blanket’s edges consistent.

The Kessler folder’s routing slips were the kind of paper nobody ever reads twice, which was why June read each one three times. Most were exactly what they claimed to be. One was not.
It was a transfer slip, moving a subset of the Kessler material between rooms, and it carried two things that did not belong together: a date stamp for a Saturday in the fall of 1996, and a coffee ring, dried pale brown, half over the stamp itself. The stamp said the office was working. The county’s own personnel rules said the office was closed. Aldous had told her the same thing across a diner table: nobody worked weekends in 1996. That was the point.
A stamp could be misdialed. Stamps were misdialed constantly; she had corrected a dozen herself during the digitization. So she did not write the word she was thinking. She requested the building’s access log for that month instead, because the records annex had used badge readers since 1995, and badge readers do not misdial.
The log came back with exactly one entry for that Saturday. One badge, in at 7:41 in the morning, out at 2:15 in the afternoon. Six and a half hours, alone, in a closed building, on the weekend the transfer slip was stamped.
The badge was not assigned to a person. It was assigned to the records office itself, a departmental badge, the kind kept in a drawer for temps and visitors and anyone whose hands were full. Whoever spent that Saturday inside had either known that badge existed or been handed it, and either way the log recorded a room, not a name.
June wrote it up flat, the stamp, the ring, the badge, the hours, and added it to the review file. Then she called the retirees’ association again, because Aldous had given her one more name on the way out of the diner: if you want to know what actually happened in that building in 1996, he had said, you talk to Judge Brey. The judge kept notebooks. The judge kept everything.
This Week’s Evidence: The Coffee Ring Square
Chapter Twelve turns on a stain that pins a document to a day, so week twelve’s square is the stain: one imperfect caramel ring on a parchment page.

Square Notes
Pin the whole ring before sewing any of it, then push it slightly out of round on purpose: a true circle reads as a design motif, a slightly eccentric one reads as a cup. Let the overlap ends cross visibly rather than hiding the join; the crossing is the realism.
