About this book
In a court full of watchers, can one young reporter trust reason more than fear?
Joseph Rouletabille leaves Paris for a dangerous case in the Russia of the Tsar. Very young and sharply observant, he approaches a mystery like a mathematician facing an equation. But here, the problem unfolds in a tense political world, where the court lives under the threat of plots.
In The Secret of the Night, Gaston Leroux sets a logical mind against secrecy, spies and sudden threats. Rouletabille relies on reasoning rather than rumour as he follows the case. Short chapters keep the story moving, while Leroux's taste for strange detail gives this detective puzzle the energy of an old-fashioned adventure.

A boy reporter arrives and eats the caviar
Rouletabille reaches the datcha des Iles at the personal wish of the Emperor. He is asked to save General Feodor Trebassof. The general's wife, Matrena, believes the danger comes only from Nihilists, and she does not want a boy to risk his life.
She finds him alone at a table of snacks, scraping the last caviar from the jars. She cries out that he is only a boy. Yet he has already noticed a fresh boot print in spilled beer, and he says nothing about it.
