Inside the convent they could hear birdsong all through the dinner hour. Some of the girls began to cry and others laughed out loud. The sisters remembered things they had long forgotten, from a time when they were young and filled with faith. No one noticed that Lea was late, and that when she arrived she sat down beside Renée, as if they were friends and had always been so, and that beneath the table, out of sight, Lea handed her a chocolate bar she’d stolen from the kitchen.

When the time came for Lea to ask the heron for what she wanted, she brought a pan of bread and milk into the courtyard as an offering. She had practiced the phrases so often through the night that the girls in the attic thought she was singing them to sleep, and even Renée closed her eyes and dreamed of things she had never seen before, trees made of flowers, beaches of black sand, clouds that were spun out of rain.

The heron came down from the roof when Lea entered the courtyard. After he’d had his breakfast, she begged for a moment of his time. It was a poor attempt at speaking his language, but he gazed at her with his yellow eyes, doing his best to understand her. When he didn’t immediately swoop away, she went on, hopeful he would help her. She asked politely for what she wanted, pleading for him to go back to the house in Paris.

Please find him for me.

She had no idea that Ava had already asked the heron to do this one kindness for her. And so he allowed her to tie the metal canister to his leg, though he was no one’s servant, and looked the other way as she did so.

Her script was tiny and neat. She’d used pale blue ink she’d found in the mother superior’s office when Ava sent her to deliver bread and jam and a pot of tea. She’d taken a pen as well, for she’d been taught to be a thief when the need arose.

I am fine, but no one knows me as you do. Please stay alive.
