In the Plaza of Dark Delights, which lies seven blocks south of the Marsh Gate and extends from the Fountain of Dark Abundance to the Shrine of the Black Virgin, the shop-lights glinted upward no more brightly than the stars glinted down. For there the vendors of drugs and the peddlers of curiosa and the hawkers of assignations light their stalls and crouching places with foxfire, glowworms, and fire-pots with tiny single windows, and they conduct their business almost as silently as the stars conduct theirs.
