Nyx put two drawings on the table and covered the names above them.
"Look at the marks first."
I leaned closer.
Three short notches above a crossbar. On one page, the lowest notch had been drawn slightly crooked. On the other, the crossbar was longer.
"Same receiving mark?"
"Same desk. Copied from two different impressions."
I moved the nearer page toward the window. The crooked notch stayed crooked. I had spent enough time copying old seals lately to know that a small difference could belong to the copy, not the object it described.
"Are those lengths measured?"
"No. The references identify the office. The drawings help you compare what you saw."
"So I shouldn't build an argument around the longer crossbar."
"I'd rather you didn't."
I left the page where both of us could see it. She hadn't brought me a perfect impression, and she hadn't claimed to.
She uncovered the headings.
