It was the end of the opera season and as they got closer to the city centre and the Roman arena, the more pedestrians there seemed to be. Women with silver handbags and flowing evening robes, men in bow ties and tortoise-shell glasses. Some carried instrument cases. The gelaterias and the neon-lit cafes were all doing brisk business. Carabinieri in khaki uniform and riding-boots walked along the pavement, heedless of the admiring glances that they attracted. There were other policemen on horseback.
