Wren read it sitting on the stone wall at the edge of the site, in the full afternoon sun, while Madame Dubois stood nearby and didn't speak.

Wren -

I know there's nothing I can say that will fix this. There's probably nothing I can say that will even begin to explain it, and I'm not sure I have the right to ask you to understand. But I'm going to try.

His name is Karim. I met him in Essaouira last October - you know how I always said I'd never be the girl who loses her head over a man? Turns out I'm exactly that girl. I fell in love with him fast and hard and I thought it was the best thing that had ever happened to me.

Last winter he got into trouble. The kind of trouble that doesn't go away with time and patience - the kind where someone is going to get hurt if you don't come up with money. I don't want to tell you more than that, because the less you know the better. His family couldn't help. My family couldn't help, not fast enough, not enough. I thought about everything I had and I thought about the cottage.

I know you had a key to the safe-deposit box. I know you trusted me with that key. I took the property documents and I sold your half without asking you. I am telling you now, in writing, because I couldn't face telling you any other way: I am a coward, and I betrayed you, and I am so sorry.

When I got the money and gave it to Karim, I thought things would be better. They weren't better. But that is my problem, not yours.

I know I have no right to ask you to forgive me. I'm asking anyway. Partly because you're my best friend in the world and the thought of losing you is - I can't finish that sentence. And partly because I need you to know that I know what I did. I'm not pretending. I'm not making excuses. I took something that was yours and I spent it because I was frightened and in love and I thought I knew what I was doing.

I'm so sorry, Wren. Please be angry at me. You have every right to be.

- Callie

Wren folded the letter.

She sat with it for a minute, maybe more. Madame Dubois put a hand on her shoulder and didn't say anything, which was exactly right.

She wasn't as angry as she'd expected to be. There was anger - yes, a current of it, hot and specific - but what was louder was the sick worry: Karim got into trouble. The kind where someone gets hurt. What kind? Was Callie safe? Where was Callie now?

She filed the worry. She'd address it when she had a grip on the practical situation.

The practical situation.

She opened the Chambre des Notaires database on her phone and navigated to the property records search. Her father had worked for a real estate attorney for twenty years; she'd grown up watching him trace chains of title the way other people did crossword puzzles. She knew how to look.

The deed of record for the Ménerbes property, parcel 2047-B, listed two co-owners: CALLAHAN, Wren Elisabeth and MORGAN, Calliope Jane, each holding an undivided one-half interest.

The transfer document filed two months ago bore only one signature: Morgan, Calliope J.

Just one.

She called her brother.

"Arch."

"Hey," Archer said. He was in Chicago, she could tell from the background noise - a coffee shop, probably, his usual Tuesday-afternoon office away from the office. "You're alive. What time is it there?"

"Four-thirty. Listen. Callie sold the cottage without my signature. Just her half, on a deed that required both our signatures. Is that a valid transfer?"

A pause. "Where are you?"

"Standing in the rubble of my house."

Longer pause. "Tell me you're joking."

"I'm standing in the rubble of my house, Archer. Just talk me through the French property law."

He talked her through it. The short version was: no, a single co-owner could not unilaterally convey the entire property. The buyer had purchased, at best, Callie's undivided one-half interest, and even that transfer was arguably defective without Wren's written consent if the deed's governing language required joint action. The demolition of the structure was almost certainly a tortious act. The development of the land would require either Wren's consent or a formal partition proceeding through the French courts.

"So you still own half," Archer said.

"I still own half."

"What does the buyer plan to do with it?"

She looked up the hill. Through the cypress trees, barely visible above the ridge line, she could see the towers of the old Fontaine estate. Château des Lavandes. She knew it, vaguely - everyone in the valley knew it, or knew of it. A two-hundred-year-old Provençal manor that the Fontaine family had owned for generations, recently acquired by some American whose name she couldn't remember. There were rumors of a boutique hotel development, which had made various people in the village unhappy.

"Avery Hospitality," she said. "Boutique hotel development."

"Okay." She could hear Archer typing. "I can get you in touch with a French property attorney I know in Lyon. But Wren - you have standing. That's real. If this guy is serious about developing, he needs your interest extinguished properly. You have leverage."

She folded the letter again. Put it in her pocket.

"Madame Dubois," she said, "which road goes to the château?"

The cypress drive was as long as a small runway. She walked it in the full afternoon sun, backpack on, violin case in hand, sweat at her temples and dust on her boots, and she did not once look uncertain about where she was going. This was a technique she had developed across thirteen months and approximately forty countries: if you look like you know where you are going, most people will assume you belong there.
