About this book

He can control a locomotive at speed. Can he control his urge to kill?

Jacques Lantier drives the railway line between Paris and Le Havre, finding comfort in the demanding care of his locomotive, Lison. Away from the engine, desire brings a violent impulse he fears. Then a glimpse of a crime beside the track draws him into a murder investigation.

Roubaud, a railway official, and his young wife, Séverine, are caught in that crime. Their marriage rests partly on the protection of Grandmorin, whose connection with Séverine holds a dark history. As Jacques grows closer to her, love and the search for safety become entangled with jealousy and danger.

“Zola was an artist, and one of the very greatest, but even before and beyond that he was intensely a moralist, as only the moralists of our true and noble time have been.”
William Dean HowellsAmerican author, critic, and playwright

In short

Picture a night express racing through the dark, its lit windows flashing past, and in one of them a man driving a knife into another man's throat. The only witness is a driver standing alone in a field, and a second later he cannot be sure he saw it at all.

A small lie about a ring ignites violence

In February 1869, in a cramped room beside the Paris station of the Western Railway, Roubaud, an assistant stationmaster from Havre, shares a quick lunch with his young wife Séverine. The mood is warm. She gives him a new knife with an ivory handle, and they talk of President Grandmorin, the rich railway director who raised her and once saved Roubaud's job.

What is The Monomaniac (La Bête Humaine) about?

It follows an assistant stationmaster, his wife and an engine driver after the murder of a judge on a night express. Jealousy, hidden crimes and inherited violence tie them together on the railway between Paris and Havre.

What does La Bête Humaine mean?

The French title means the human beast. Zola uses it for the violent animal instinct that lives inside ordinary people and breaks out in jealousy, desire and the urge to kill.

Is La Bête Humaine part of a series?

It is the seventeenth novel in Zola's Rougon-Macquart cycle, which follows one family across several generations. Jacques Lantier belongs to that family, and you can read the book on its own without knowing the others.

The author

Émile Zola

1840–1902 · French novelist

Émile Zola (1840–1902) was a French novelist, journalist, playwright, and poet. He was born in Paris, grew up in Aix-en-Provence, and later lived in Paris and Médan. He wrote Thérèse Raquin (1867), Nana (1880), and Germinal (1885). His twenty-novel series, Les Rougon-Macquart, appeared between 1871 and 1893.

“People may invent even finer machines, but there will still be wild beasts, whatever happens.”
The Monomaniac (La Bête Humaine), aunt Phasie, chapter 2
