" Sunset’s the best time to take a stroll down Mouffetard, the ancient Via Mons Cetardus. The buildings along it are only two or three stories high. Many are crowned with conical dovecotes. Nowhere in Paris is the connection, the obscure kinship, between houses very close to each other more perceptible to the pedestrian than in this street.

Close in age, not location. If one of them should show signs of decrepitude, if its face should sag, or it should lose a tooth, as it were, a bit of cornicing, within hours its sibling a hundred metres away, but designed according to the same plans and built by the same men, will also feel it’s on its last legs.

The houses vibrate in sympathy like the chords of a viola d’amore. Like cheddite charges giving each other the signal to explode simultaneously. "
