watched the proceedings and listened to what was said, for he considered it his duty to attend on such an occasion, his dog at his heels, his gun slung over his shoulder. He listened and looked from one to the other with his deep eyes and inscrutable parchment face, shrivelled by the malarious fever. But he said nothing. The Chief of Police turned to him at last.
"Now what do you think about it?" asked the official. "You know the country. Had there been any suspicious characters about, fellows who could have carried off the boy?"
"Such people would ask a ransom," answered Ercole. "You would soon hear from them. But I saw no one. There have been no brigands about Rome for more than twenty years. Do you dream that you are in Sicily? Praise be to Heaven, this is the Roman Campagna; we are Christians and we live under King Victor! Where are the brigands? They have melted. Or else they are making straw hats in the galleys. Do I know where they are? They are not here. That is enough."
"Quite right, my friend," answered the Chief of Police. "There are no brigands. But I am sorry to say that there are thieves in the Campagna, as there are near every great city."
Ercole shrugged his angular shoulders contemptuously.
"Thieves would not carry a man away," he answered. "You know that, you who are of the profession, as they say. Such ruffians would have knocked the young gentleman on the head to keep him quiet, and would have made off. And besides, we should have found their tracks in the sand, and Nino would have smelt them."
Nino pricked up one ragged ear at the sound of his name.
"He does not look very intelligent," observed the official. "A clever dog might have been used to track the boy."
"How?" inquired Ercole with scorn. "The footsteps of the young gentleman were everywhere, with those of all the family, who were always coming and going about here. How could he track them, or any of us? But he would have smelt a stranger, even if it had rained. I know this dog. He is the head dog on the Roman shore. There is no other dog like him."
"I daresay not," assented the Chief of Police, looking at Nino. "In fact, he is not like any animal I ever saw."
The detectives laughed at this.
"There is no other," said Ercole without a smile. "He is the only son of a widowed mother. I am his family, and he is my family, and we live in good understanding in this desert. If there were no fever we should be like the saints in paradise—eating our corn meal together. And I will tell you another thing. If the young gentleman had been wounded anywhere near here, Nino would have found the blood even after three days. As for a dead man, he would make a point for him and howl half a mile off, unless the wind was the wrong way."
"Would he really?" asked Corbario with a little interest.
Ercole looked at him and nodded, but said no more, and presently the whole party of men went back to Rome, leaving him to the loneliness of the sand-banks and the sea.
Then Ercole came back to the gap and stood still a little while, and his dog sat bolt upright beside him.
"Nino," he said at last, in a rather regretful tone, "I gave you a good character. What could I say before those gentlemen? But I tell you this, you are growing old. And don't answer that I am getting old too, for that is my business. If your nose were what it was once, we should know the truth by this time. Smell that!"
Ercole produced a small green morocco pocket-book, of the sort made to hold a few visiting cards and a little paper money, and held it to Nino's muzzle.
Nino smelt it, looked up to his master's face inquiringly, smelt it again, and then, as if to explain that it did not interest him, lay down in the sand with his head on his forepaws.
"You see!" growled Ercole. "You cannot even tell whether it belonged to the boy or to Corbario. An apoplexy on you! You understand nothing! Ill befall the souls of your dead, you ignorant beast!"
Nino growled, but did not lift his head.
"You understand that," said Ercole, discontentedly. "If you were a Christian you would stick a knife into me for insulting your dead! Yet you cannot tell whose pocket-book this is! And if I knew, I should know something worth knowing."
The pocket-book disappeared in the interior recesses of Ercole's waistcoat. It was empty and bore no initial, and he could not remember to have seen it in Corbario's or Marcello's hands, but he was quite sure that it belonged to one of them. He was equally sure that if he showed it to Corbario the latter would at once say that it was Marcello's, and would take it away from him, so he said nothing about it. He had found it in the sand, a little way up the bank, during his first search after Marcello's disappearance.
Ercole's confidence in the good intentions of his fellow-men was not great; he was quite lacking in the sort of charity which believeth all things, and had a large capacity for suspicion of everybody and everything; he held all men to be liars and most women to be something worse.
"Men are at least Christians," he would say to Nino, "but a female is always a female."
If he took a liking for any one, as for Marcello, he excused himself for the weakness on the ground that he was only human after all, and in his heart he respected his dog for snarling at everybody without discrimination. There was no doubt, however, that he felt a sort of attachment for the boy, and he admitted the failing while he deplored it. Besides, he detested Corbario, and had felt that his own common sense was insulted by the fact that Folco seemed devoted to Marcello. The suspicion that Folco had got rid of his stepson in order to get his fortune was therefore positively delightful, accompanied as it was by the conviction that he should one day prove his enemy a murderer. Perhaps if he could have known what Folco Corbario was suffering, he might have been almost satisfied, but he had no means of guessing that. In his opinion the man knew what had become of Marcello, and could be made to tell if proper means were used. At night Ercole put himself to sleep by devising the most horrible tortures for his master, such as no fortitude could resist, and by trying to guess what the wretched man would say when his agony forced him to confess the truth.
He was almost sure by this time that Marcello was dead, though how Folco could have killed him, carried off his body to a great distance and buried him, without ever absenting himself from the cottage, was more than Ercole could imagine. He paid Corbario's skill the compliment of believing that he had not employed any accomplice, but had done the deed alone.
How? That was the question. Ercole knew his dog well enough, and was perfectly sure that if the body had been concealed anywhere within a mile of the cottage Nino would have found it out, for the dog and his master had quartered every foot of the ground within three days after Marcello had been lost. It was utterly, entirely impossible that Folco, without help, could have dragged the dead boy farther. When he had gone on his pretended search he had not been alone; one of the men had ridden with him, and had never lost sight of him, as Ercole easily ascertained without seeming to ask questions. Ercole had obtained a pretty fair knowledge of Corbario's movements on that day, and it appeared that he had not been absent from the cottage more than half an hour at any time before he went to look for Marcello.
"If Corbario himself had disappeared in that way," said Ercole to himself and Nino, "it would be easy to understand. We should know that the devil had carried him off."
But no such supernatural intervention of the infernal powers could be supposed in Marcello's case, and Ercole racked his brains to no purpose, and pondered mad schemes for carrying Corbario off out of Rome to a quiet place where he would extract the truth from him, and he growled
