Monsieur Lecoq

At about eleven o'clock in the evening of the 20th of February, 186—, which chanced to be Shrove Sunday, a party of detectives left the police station near the old Barriere d'Italie to the direct south of Paris. Their mission was to explore the district extending on the one hand between the highroad to Fontainebleau and the Seine, and on the other between the outer boulevards and the fortifications. This quarter of the city had at that time anything but an enviable reputation. To venture there at night was considered so dangerous that the soldiers from the outlying forts who came in to Paris with permission to go to the theatre, were ordered to halt at the barriere, and not to pass through the perilous district excepting in parties of three or four.
