Lire le chapitre 19: The Poison Locket Unlocked

The audience with Madame de Maintenon bore fruit faster than Marguerite dared hope. Three days after handing over the forged letter and the empty vial, she was summoned to a narrow antechamber off the Galerie des Glaces, where two of Maintenon's most trusted men awaited her.

“The Comtesse de Villeroy’s apartments,” said the taller one, a grey-faced man named Duval who smelled of ink and old leather. “Madame de Maintenon wishes them searched. You know the rooms. You will guide us and say nothing to anyone.”

Marguerite’s heart thrummed against her ribs. The Comtesse was at a morning concert with the Duchesse—she had seen them depart together, arm in arm, the Comtesse’s smile like a blade wrapped in velvet. There was perhaps an hour before they returned.

The Comtesse’s chambers were immaculate, scented with lavender and something sharper beneath. Marguerite watched the two men work in silence, turning cushions, parting wall panels, slipping fingers between the pages of a gilt-edged book of hours. She had already told them of the hidden drawer, but it was empty now—the locket and letters she had stolen were in Maintenon’s keeping, and the Comtesse had not replaced them.

“Nothing,” Duval muttered.

Then the younger man, lean and quick-eyed, knelt by the hearth. His hand passed along the stones, paused, pressed. There was a soft click. A stone slid forward, revealing a cavity lined with black velvet.

Inside lay a locket.

Marguerite’s breath caught. It was not hers—hers hung still beneath her bodice, warm with her own skin. But it was its twin: same oval shape, same chased silver pattern of laurel leaves, same delicate clasp shaped like a fleur-de-lis.

Duval lifted it and opened it.

The Duchesse de Montfort stared back at them, painted in miniature, her pale throat and dark hair caught with impossible precision. The portrait was not recent. The Duchesse wore a gown from five years past, and her face was younger, unlined by the worry that now creased her brow.

“Well,” said Duval, and his voice was flat. “That is that.”

Marguerite's throat tightened. A locket like her own, kept in a secret cavity in the hearth, bearing the image of her mistress. It was a collector’s piece. A hunter’s trophy. A promise.

“The Comtesse will be arrested,” the young man said.

“Not yet,” Duval replied. He looked at Marguerite. “You will tell no one. Go back to your duties. When Madame de Maintenon gives the word, we move.”

She returned to the Duchesse’s chambers on wooden legs. The painting of the Duchesse’s face, so serene, so unaware of its own doom, kept rising before her eyes. The Comtesse had not merely poisoned her. She had commemorated her. She had planned to own her death before she had even ensured it.

The arrest came at dusk.

Marguerite was in the linen closet when she heard the commotion—boots on marble, a woman’s high, furious voice, the slam of a door. She pressed her eye to the crack of the hinges and saw the Comtesse de Villeroy being escorted down the corridor by Duval and three soldiers of the King’s guard.

The Comtesse’s skirts were gathered in one hand, her face white with fury, but she was not broken. She dragged her feet, forcing them to slow.

“You make a grave error,” she said, and her voice carried, cold and clear down the gallery. “You think you have caught me? You have caught a servant.”

Duval did not answer.

“Ask her,” the Comtesse called out, louder now, her eyes sweeping the corridor as if seeking a witness. “Ask the Duchesse de Montfort. I acted on her orders. Everything I did, everything I gave her, she commanded it.”

Marguerite’s blood turned to ice.

The soldiers kept walking. The Comtesse’s voice rose, desperate now, brittle as glass.

“She wanted to be rid of her husband! She wanted to control her inheritance! I was her instrument, not her executioner! Ask her who wrote the letter! Ask her whose name is signed on the order!”

The door of the Duchesse’s chamber opened.

Marguerite saw her mistress standing there, ghost-pale, one hand braced on the frame. The Duchesse had heard. Everyone had heard.

“That is a lie,” the Duchesse said, but her voice was thin, and it cracked on the last word.

The Comtesse twisted in the soldiers’ grip, her face alight with triumph.

“Is it, Your Grace? Then why did you give me your hair? Why did you ask me to find a man who could be discreet? You said he was a jeweler. You told me it was for your husband’s gift.”

The Duchesse shook her head, but her hand trembled on the doorframe. Marguerite saw the terror in her eyes—not terror of poison, but terror of a truth she could not name.

The Comtesse laughed, a sharp, breaking sound.

“They will hang me,” she said. “But I will dance on the gallows with your name on my lips. We shall see which of us the King believes.”

The soldiers pulled her away. The corridor fell silent.

The Duchesse stood alone in the doorway, her face a mask of disbelief, her fingers still gripping the wood as if it were the only thing keeping her upright.

Marguerite did not move from the linen closet. In her pocket, her own locket pressed against her thigh—a twin to the one they had found. And she understood, with a cold, clear certainty, that the locket was not a trophy.

It was a mirror.

Someone had placed that locket in the Comtesse’s hearth. Someone who knew Marguerite’s story. Someone who wanted the Comtesse caught, but not with the true evidence—only with a lie dressed in enough truth to hang her.

The Comtesse was arrested. But someone else was still free.
