No sound, however, rewarded him. He spent the day in a dreadful tension between hope and despair—snarled over the periodic visits of his gaolers—snarled them from his presence—was for ever crouching and listening. They fancied his wits going, and nudged one another and grinned. He never thought to question them; was always one of those strong souls who find, not ask, the way to their own ends. He knew they would lie to him, and was only impatient of their company. Seeing his state, they were at the trouble to take some extra precautions, always posting a guard on the stairs before entering his cell. Messer Lanti, normal, was sufficiently formidable; possessed, there was no foretelling his possibilities. But they might have reassured themselves. Escape, at the moment, was farthest from his thoughts or wishes. He would have stood for his dungeon against the world; he clung to his wall, like a frozen ragamuffin to the outside of a baker’s oven. Presently he bethought himself of an occupation, at once suggestive and time-killing. He had been wearing his spurs when captured—weapons, of a sort, overlooked in the removal of deadlier—and these, in view of vague contingencies, he had taken off and hidden in his bed. His precaution was justified; he saw a certain use for them now; and so, procuring them, set to work to enlarge with their rowels the opening of the rat hole. He wrought busily and energetically. Messer Topo sat by him a good deal, watching, with courteous and even curious forbearance, this really insolent desecration of his front door. They dined together as usual; and then Carlo returned to his work. His plan was to enlarge the opening into a funnel-like mouth, meeter for receiving and conveying sounds. It had occurred to him that the point of the tiny passage’s issue into the next cell might be difficult of localisation by one imprisoned there, especially if the search—as he writhed to picture it—was to be made in a blinding gloom. If he could only have continued to help by his voice—to cry ’Here! Here!’ in this tragic game of hide-and-seek! He wrought dumbly, savagely, nursing his lungs against that moment. But still by night it had not come to be his. Then, all in an instant, an inspiration came to him. He sat down, and wrote upon a slip of paper: ’_From Carlo Lanti, prisoner and neighbour. Mark who brings thee this—whence he issues, and whither returns. Speak, then, by that road_—’ and having summoned Messer Topo, fastened the billet by a thread about his neck, and, carrying him to his run, dismissed him into it. Wonder of wonders! the great little beast disappeared upon his errand. Henceforth kill them for vermin that called the rat by such a name! Messer Topo did not return. What matter, if he had sped his mission? Only, had he? There was the torture. Hour after hour went by, and still no sign.
