“Since my sister has decided to interrupt our wedding,” I said, and my voice surprised even me with how clear it sounded, “everyone deserves the truth. Not the version she tells when she wants sympathy. The truth.”

Valentina gave a sharp laugh. “Please. You mean your truth.”

“No,” I said. “I mean the kind with proof.”

Something changed in her face at that word. It was tiny, but I saw it. Diego saw it too. My mother, seated in the front row, looked as though she might faint. My father rose halfway from his chair, then sat again when he realized no one was rushing to defend Valentina this time.

“When we were nineteen,” I said, “Diego wrote me a letter.”

A rustle moved through the guests.

Valentina’s expression hardened.
