The Fat and the Thin by Émile Zola

A week later, Florent thought that he would at last be able to proceed to action. A sufficiently serious outburst of public dissatisfaction furnished an opportunity for launching his insurrectionary forces upon Paris. The Corps Législatif, whose members had lately shown great variance of opinion respecting certain grants to the Imperial family, was now discussing a bill for the imposition of a very unpopular tax, at which the lower orders had already begun to growl. The Ministry, fearing a defeat, was straining every nerve. It was probable, thought Florent, that no better pretext for a rising would for a long time present itself.

One morning, at daybreak, he went to reconnoitre the neighbourhood of the Palais Bourbon. He forgot all about his duties as inspector, and lingered there, studying the approaches of the palace, till eight o'clock, without ever thinking that his absence would revolutionise the fish market. He perambulated all the surrounding streets, the Rue de Lille, the Rue de l'Université, the Rue de Bourgogne, the Rue Saint Dominique, and even extended his examination to the Esplanade des Invalides, stopping at certain crossways, and measuring distances as he walked along. Then, on coming back to the Quai d'Orsay, he sat down on the parapet, and determined that the attack should be made simultaneously from all sides.
