"Then make your peace with your gods," said the officer, drawing his sword and pushing the door open, "for you are about to die." There was a cold smile upon his lips as he stepped across the threshold, for Caesar knew his men and had chosen well the proper type for this deed--a creature without conscience whose envy and jealousy Praeclarus had aroused, and the smile was still upon his lips as the sword of Appius Applosus crashed through his helmet to his brain. As the man lunged forward dead, the torch fell from his left hand and was extinguished upon the floor. "Now go," whispered Praeclarus to Applosus, "and may the gratitude of those you have saved prove a guard against disaster." "It could not have turned out better," whispered Applosus. "You have the keys; you have his weapons, and now you have ample time to make your escape before the truth is learned. Good-by, again. Good-by, and may the gods protect you." As Applosus moved cautiously along the dark corridor, Maximus Praeclarus fitted keys to their manacles and both men stood erect, freed at last from their hated chains. No need to formulate plans--they had talked and talked of nothing else for weeks, changing them only to meet altered conditions. Now their first concern was to find Hasta and Metellus and the others upon whose loyalty they could depend and to gather around them as many of the other prisoners as might be willing to follow them in the daring adventure they contemplated. Through the darkness of the corridor they crept from cell to cell and in the few that still held prisoners they found none unwilling to pledge his loyalty to any cause or to any leader that might offer freedom. Lukedi, Mpingu, and Ogonyo were among those they liberated. They had almost given up hope of finding the others when they came upon Metellus and Hasta in a cell close to the entrance to the arena. With them were a number of professional gladiators, who should have been liberated with the other victors at the end of the games, but who were being kept because of some whim of Caesar that they could not understand and that only inflamed them to anger against the Emperor. To a man they pledged themselves to follow wherever Tarzan might lead. "Few of us will come through alive," said the ape-man, when they had all gathered in the large room that was reserved for the contestants before they were ushered into the arena, "but those who do will have been avenged upon Caesar for the wrongs that he has done them." "The others will be welcomed by the gods as heroes worthy of every favor," added Praeclarus. "We do not care whether your cause be right or wrong, or whether we live or die," said a gladiator, "so long as there is good fighting." "There will be good fighting. I can promise you that," said Tarzan, "and plenty of it." "Then lead on," said the gladiator. "But first I must liberate the rest of my friends," said the ape-man. "We have emptied every cell," said Praeclarus. "There are no more."
