Every inch of space was used. As the road narrowed, signs receded upwards and changed to the vertical. Businesses simply soared from ground level and hung out vaster, more fascinatingly illuminated shingles than competitors. We were still in a traffic tangle, but now the road curved. Shops crowded the pavements and became homelier. Vegetables, spices, grocery produce in boxes or hanging from shop lintels, meats adangle - as always, my ultimate ghastliness - and here and there among the crowds the alarming spectacle of an armed Sikh, shotgun aslant, casually sitting at a bank entrance. And markets everywhere. To the right, cramped streets sloped down to the harbor.
