But Cestus was either not so keen of hearing, or else was too impatient to make a speedy end of the business, so that, after listening for a brief second or two, he snarled in reply, ‘What horses, you fool; there are no horses out this time of the night, on this road—just as likely the goddess herself—be ready for the whistle!’ With that he rejoined the party, who were resting unconscious of such a dangerous trap. They had scarcely taken half a dozen steps onward, when Cestus gave his signal, shrill and sudden. Four forms leaped like tigers from the shadow of the altar and fell on the affrighted slaves. Cestus himself bounded on Fabricius. At the same time the figure, which had dogged their steps from the Janiculum, leaped down from the rock‐wall of the road and stood apart to watch. Two of the slaves had fallen in the sudden onslaught, but the third had managed to escape at the top of his speed. Fabricius, who, in despite of his age, retained yet a large use of his keen senses and bodily activity, had taken sufficient warning to raise his staff, and meet the charge of Cestus with a vigorous blow. The ruffian staggered, and the moonbeams flashed upon the polished blade of a weapon, which was dashed from his hand by the lucky stroke. ‘Wretch!’ the old man shouted, when a blow from behind felled him senseless. Cestus, furious with rage and pain, belched forth a frightful imprecation. His right arm was benumbed or broken, and he stooped for his knife with his other hand. Not far away was a sharp turn in the road. The tramp of horses and the jingle of accoutrements smote on their ears. ‘Bungling fool!’ hissed the mysterious figure, springing forward to complete the work in which, so far, the Suburan had been foiled. But he was met, and rudely thrust back by the powerful arm of the confederate who had knocked the Senator down from behind. ‘Take your time, my lad,’ bellowed that individual hoarsely, ‘he’s more mine than yours.’
