The Slow Burn Letter

The letter is the secret engine of historical romance.

I have spent a long time thinking about why. In modern romance, we have texts, calls, voicemails, video chats — constant low-stakes correspondence. The lovers are always five seconds from each other. The romantic gesture is small and fast: a meme, a song link, a thinking of you at 11pm.

In historical romance, a letter is the only unsupervised conversation two characters can have. The room is gone. The chaperone is gone. The drawing room and the gallery and the ballroom and the family dinner — all gone. There is only the page, and the silence around it, and the recipient unfolding it alone at the window.

That is where the romance happens.

The four parts of a romance letter

When I write a letter into a book, I’m almost always working with four moves, in order. They don’t have to all be there, but the better letters have all four:

1. The address. Who he is calling her, on the page where no one else will see it. Madam, in chapter eleven. My dear Miss Bennet, in chapter sixteen. Elizabeth, in chapter twenty-three. The address is the romance arc.
2. The pretext. The reason he’s allowed to write. A book she lent him. A small favour she did. A piece of news she will want to know. The pretext is the alibi the letter needs to exist.
3. The breach. The line where the letter stops being about the pretext and starts being about the thing he could not say in person. The reader will see the breach a sentence before the letter writer realises he’s made it. That’s the catch in the chest.
4. The close. Who he is, by the end. Yours, F. Darcy. Your servant. Faithfully. Always. The close is the contract he is offering. If you read the letter for the closes alone, you have the whole arc of the romance.

The letter as a slow burn

This is the thing I keep coming back to. The letter is slow.

He writes it. He posts it. She receives it on the third day. She reads it that night. She reads it again in the morning. She decides whether to reply. She sleeps on her reply. She writes the first version. She burns the first version. She writes the second version. She hesitates over the close. She seals it. She posts it. He receives it on the fifth day.

That’s nine days of nothing happening in the room, and everything happening on the page. The reader sits in those nine days with both characters. That is what a slow burn actually is — not nine months of plot, but nine days where the only romance is the folded paper traveling across the country.

If I could only have one tool to write historical romance, it would be the letter. Everything else is decoration. The letter is the engine.
