The letter arrived sealed in a manner none of them had seen before — waxed twice, in two different colors, with a small pressed emblem Hamo eventually identified, after some study, as belonging to a Genoese trading house of genuine standing rather than any minor merchant's private seal.
To the Lord and Lady of Argenton, it began, in careful, formal Latin that Victoria read aloud at the tally-bench with growing, cautious interest, I write at the direction of my house, having received the report of our agent Corradino regarding the currency and medicine your town has developed. My house has interests in several trading ports along this coast and would welcome the opportunity to establish formal correspondence, and in time, formal trade, should your council find such an arrangement agreeable. I am aware, from Corradino's own account, that his presence in your valley was met with more grace than his profession generally earns him elsewhere, and my house does not forget such courtesies easily.
"He kept his word," Thomas said, reading it over her shoulder. "He told us he'd report honestly. He actually did."
"Which tells you something useful about the man who sent him, whatever else you decide about the house he serves." Victoria set the letter down, already turning it over with the particular calculating focus she brought to any genuine opportunity. "A trading house that values an honest report enough to write to us directly, rather than simply sending a second, better-hidden agent, is a house that intends to deal with us properly if we let them. That's rarer than you'd think, in my experience of merchants."
Alaric, called in to review the letter for anything his own eleven years might catch that the rest of them would miss, read it twice with obvious care. "I would proceed cautiously, but I would proceed," he said finally. "A formal trading relationship with a house of this standing does two things at once — it opens a market considerably larger than anything the March alone could offer you, and it gives you a powerful ally with no particular loyalty to the Baron's successor, should the Crown ever appoint one troublesome enough to matter again. I would want assurances, though, about what exactly they intend to learn from such an arrangement beyond the scrip's exchange rate."
"They'll want to know how it's made," Hamo said. "The scrip, and very likely the medicine besides. That is simply the nature of any trade relationship worth having — knowledge moves in both directions, or it isn't truly a partnership at all."
Victoria was quiet for a long moment, weighing something Thomas recognized from the particular stillness of her face. "Then we control what moves, and how quickly. I'll answer this myself, and I'll propose exactly the same terms Anselm accepted from us on the steam design — enough truth to build genuine trust, held back carefully enough that no single letter could hand a rival everything we've spent three years building." She looked up at Thomas. "I want to write this one alone, if you don't mind. Not because I don't trust your instincts. Because a house like this will read every word for what it says about who actually holds authority here, and I'd rather they understand from the very first letter that this valley's diplomacy runs through more than one hand."
Thomas found, turning the request over, that it cost him nothing at all to agree, and understood, watching her already reaching for a fresh sheet, that some quiet shift had occurred in the town's governance that he hadn't fully registered until this exact moment — that Victoria no longer needed his presence to make the valley's largest decisions, had perhaps not needed it for longer than either of them had openly admitted, and that this was, whatever small pang it cost his pride to recognize, precisely the outcome he had always claimed to want.
She spent three evenings composing the reply, weighing every clause with Hamo's careful eye and Alaric's practiced political sense, and it was Elias, reviewing the finished letter before it went out with the next merchant caravan, who offered the observation that stayed with Thomas longest.
"You've built something rather remarkable here, whether either of you fully credits it yet," he said, folding the letter into its traveling case. "A valley that started as one man's desperate secret now negotiates as an equal with houses in Genoa, courts in Whitcombe, and archbishops in cities neither of us has ever seen. I have mapped a great deal of this March in three years, Lord Thomas. I have never once mapped anything that grew quite this far past where it started."
The letter went south with the caravan the following morning, and Thomas stood at the gate watching it go, thinking not of Genoa or trade routes but of a small, cold gap in his mother's letters that had never fully closed in his own private accounting, however steadily every letter since had continued to arrive.
