An ancient light cruiser, the HMS Belfast,now a museum, lay tied up to the City Pier to the left, on the near bank almost at his feet. Beyond her, the clean, modern lines of the new London Bridge spanned the river, in front of the thrust and bustle of London business district and the far- off blue dome of St. Paul. To his right, downstream, rose the Tower Bridge, older and more conventional beneath its twin supporting caissons and towers that looked like the squared- off steeples of Anglican churches.The bridge architecture fitted in perfectly with the sprawl of medieval castle walls, turrets, towers, and cupolas directly across the Thames from City Hall, the infamous Tower of London.Closer at hand, the demonstration had spilled into the park and waterfront pier directly below City Hall, fillingit as far as the near end of the Tower Bridge, perhaps 150 yards away. Karr was looking down on a sea of people and brightly colored banners. Occasionally megaphone- directed chants rose the ten stories to the observation promenade, but mostly the noise was little more than a distant, subdued rumble.Anything new on the telly?
