He studied to acquire the dialects, and to familiarise himself with the habits, of the lowest quarters of Rome. He frequented the small wine-shops of the Trastevere and the Rione St. Angelo. He mastered the intricacies of the Ghetto. He haunted the street fountains, the puppet-shows, and the quays of Ripa Grande. Wherever, in short, the Roman people were to be found _in fra di loro_, whether gossiping, gaming, quarrelling, or holiday-making, there Hugh Girdlestone made his way, mingled with them, listened, observed, and waited like a trapper for his prey. It was a task of untold peril and difficulty, made all the more perilous and difficult by the fact of his being a foreigner. Fluent Italian as he was, it was still not possible that he should perfectly master all the slang of the Rione, play at morra and zecchinetta as one to the manner born, or be at all times equal to the part which he had undertaken. He was liable at any moment to betray himself, and to be poniarded for a spy. He knew each time he ventured into certain quarters of the city that his body might be floating down towards Ostia before daybreak, or that he might quite probably disappear from that moment, and never be seen or heard of more. Yet, strong in his purpose and reckless of his life, he went, and came, and went again, penetrating into haunts where the police dared not set foot, and assuming in these excursions the dress and dialect of a Roman "rough" of the lowest order.
Thus disguised, and armed with a deadly patience that knew neither weariness nor discouragement, Hugh Girdlestone pursued his quest. How, despite every precaution, he contrived to escape detection was matter for daily wonder, even to himself. He owed his safety, however, in great measure to a sullen manner and a silent tongue--perhaps in some degree to his southern complexion; to his black beard and swarthy skin, and the lowering fire in his eyes.
Thus the Spring passed away, the Summer heats came on, and the wealthier quarters of Rome were, as usual, emptied of their inhabitants. The foreign visitors went first; then the Italian nobility; and then all those among the professional and commercial classes who could afford the healthful luxury of villeggiatura. Meanwhile, Hugh Girdlestone was the only remaining lodger in the Palazzo Bardello. Day by day he lingered on in the deserted city, wandering through the burning streets and piazzas, and down by the river-side, where the very air was heavy with malaria.
