The Gropings of Flight

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.

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
