It had been a lovely day. The evening light softly illuminated the thick chestnut trees; Albert, a small grey tomcat who belonged to the children, seemed ecstatic. He rolled around on his back on the carpet. He jumped up on to the mantelpiece, nibbled at the edge of a peony in a large midnight-blue vase, delicately pawed at a snapdragon etched into the bronze corner-mount of a console table, then in one leap perched on the old man’s wheelchair and miaowed in his ear. The elder Monsieur Péricand stretched a hand towards him; his hand was always freezing cold, purple and shaking. The cat was afraid and ran off. Dinner was about to be served. Auguste appeared and pushed the invalid into the dining room.

They were just sitting down at the table when the mistress of the house stopped suddenly, Jacqueline’s spoon of tonic suspended in mid-air. “It’s your father, children,” she said as the key turned in the lock.

It was indeed Monsieur Péricand, a short, stocky man with a gentle and slightly awkward manner. His normally well-fed, relaxed and rosy-cheeked face looked, not frightened or worried, but extraordinarily shocked. He wore the expression found on people who have died in an accident, in a matter of seconds, without having had time to be afraid or suffer. They would be reading a book or looking out of a car window, thinking about things, or making their way along a train to the restaurant car when, all of a sudden, there they were in hell.

Madame Péricand rose quietly from her chair. “Adrien?” she called out, her voice anguished.

“It’s nothing. Nothing,” he muttered hastily, glancing furtively at the children, his father and the servants.

Madame Péricand understood. She nodded at the servants to continue serving dinner. She forced herself to swallow her food, but each mouthful seemed as hard and bland as a stone and stuck in her throat. Nevertheless, she repeated the phrases that had become ritual at mealtimes for the past thirty years. “Don’t drink before starting your soup,” she told the children. “Darling, your knife . . .”

She cut the elderly Monsieur Péricand’s filet of sole into small strips. He was on a complicated diet that allowed him to eat only the lightest food and Madame Péricand always served him herself, pouring his water, buttering his bread, tying his napkin round his neck, for he always started drooling when he saw food he liked. “I don’t think poor elderly invalids can bear to be touched by servants,” she would say to her friends.

“We must show grandfather how much we love him, my darlings,” she instructed the children, looking at the old man with terrifying tenderness.

In his later years, Monsieur Péricand had endowed various philanthropic projects, one of which was especially dear to his heart: the Penitent Children of the 16th Arrondissement, a venerable institution whose goal was to instil morals in delinquent minors.
