Amedeo Dorini, the hall porter of the Hotel Cavour in Milan, stood on the pavement before the hotel one autumn afternoon in the year 1894, waiting for the omnibus, which had gone to the station, and which was now due to return, bearing-Amedeo hoped-a load of generously inclined travelers. During the years of his not unpleasant servitude Amedeo had become a student of human nature. He had learnt to judge shrewdly and soundly, to sum up quickly, to deliver verdicts which were not unjust. And now, as he saw the omnibus, with its two fat brown horses, coming slowly along by the cab rank, and turning into the Piazza that is presided over by Cavour's statue, he prepared almost mechanically to measure and weigh evidence, to criticize and come to a conclusion.
