In order to understand what follows, it is requisite to form an exact idea of the Droit-Mur lane, and, in particular, of the angle which one leaves on the left when one emerges from the Rue Polonceau into this lane. Droit-Mur lane was almost entirely bordered on the right, as far as the Rue Petit-Picpus, by houses of mean aspect; on the left by a solitary building of severe outlines, composed of numerous parts which grew gradually higher by a story or two as they approached the Rue Petit-Picpus side; so that this building, which was very lofty on the Rue Petit-Picpus side, was tolerably low on the side adjoining the Rue Polonceau. There, at the angle of which we have spoken, it descended to such a degree that it consisted of merely a wall. This wall did not abut directly on the Street; it formed a deeply retreating niche, concealed by its two corners from two observers who might have been, one in the Rue Polonceau, the other in the Rue Droit-Mur.

Beginning with these angles of the niche, the wall extended along the Rue Polonceau as far as a house which bore the number 49, and along the Rue Droit-Mur, where the fragment was much shorter, as far as the gloomy building which we have mentioned and whose gable it intersected, thus forming another retreating angle in the street. This gable was sombre of aspect; only one window was visible, or, to speak more correctly, two shutters covered with a sheet of zinc and kept constantly closed.

The state of the places of which we are here giving a description is rigorously exact, and will certainly awaken a very precise memory in the mind of old inhabitants of the quarter.

The niche was entirely filled by a thing which resembled a colossal and wretched door; it was a vast, formless assemblage of perpendicular planks, the upper ones being broader than the lower, bound together by long transverse strips of iron. At one side there was a carriage gate of the ordinary dimensions, and which had evidently not been cut more than fifty years previously.

A linden-tree showed its crest above the niche, and the wall was covered with ivy on the side of the Rue Polonceau.

In the imminent peril in which Jean Valjean found himself, this sombre building had about it a solitary and uninhabited look which tempted him. He ran his eyes rapidly over it; he said to himself, that if he could contrive to get inside it, he might save himself. First he conceived an idea, then a hope.

In the central portion of the front of this building, on the Rue Droit-Mur side, there were at all the windows of the different stories ancient cistern pipes of lead. The various branches of the pipes which led from one central pipe to all these............
