"I did not like the look in his eye nor the tone of his voice," said Praeclarus, after the fellow was out of hearing. "The gods are unkind, but how can I expect else from them when even my best friend fails me?" "You mean Appius Applosus?" asked Tarzan. "None other," replied Praeclarus. "If he had fetched the keys, we might yet escape." "Perhaps we shall in any event," said Tarzan. "I should never give up hope until I were dead--and I have never been dead." "You do not know either the power or perfidy of Caesar," replied the Roman. "Nor does Caesar know Tarzan of the Apes." Darkness had but just enveloped the city, blotting out even the dim light of their dungeon cell, when the two men perceived wavering light beams lessening the darkness of the corridor without. The light increased and they knew that someone was approaching, lighting his way with a flaring torch. Visitors to the dungeon beneath the Colosseum were few in the daytime. Guards and jailers passed occasionally and twice each day slaves came with food, but at night the silent approach of a single torch might more surely augur ill than well. Praeclarus and Tarzan dropped the desultory conversation with which they had been whiling away the time and waited in silence for whoever might be coming. Perhaps the night-time visitor was not for them, but the egotism of misfortune naturally suggested that he was and that his intentions might be more sinister than friendly. But they had not long to wait and their suspicions precluded any possibility of surprise when a man halted before the barred gateway to their cell. As the visitor fitted the key to the lock Praeclarus recognized him through the bars. "Appius Applosus!" he cried. "You have come!" "Ps-st!" cautioned Applosus, and quickly opening the gate he stepped within and closed it silently behind him. With a quick glance he surveyed the cell and then extinguished his torch against the stone wall. "It is fortunate that you are alone," he said, speaking in whispers, as he dropped to the floor close to the two men. "You are trembling," said Praeclarus. "What has happened?" "It is not what has happened, but what is about to happen that alarms me," replied Applosus. "You have probably wondered why I had not brought the keys. You have doubtless thought me faithless, but the fact is that up to this instant, it has been impossible, although I have stood ready before to risk my life in the attempt, even as I am now doing." "But why should it be so difficult for the commander of the Colosseum guard to visit the dungeon?"
