The story
“Florence Granger’s father, Judge Granger, incurs the enmity of Pietro, an Italian, and when the Judge is found mysteriously murdered, Captain Ross of the Aqueduct Police arrests the foreigner on suspicion. Unable to prove anything against him, however, Ross is obliged to release Pietro. Florence, who some time before had promised to marry the young police captain, is so chagrined at his failure to discover the slayer of her father, that she breaks her engagement to him. Disguised as an Italian girl, and aided by her perfect knowledge of the language, she contrives to hide herself in the meeting place of Pietro and his band, where she overhears him describe in detail how he murdered Judge Granger. The shock causes her to faint. This leads to her discovery and, bound hand and foot, she is left by the men in care of a woman confederate. During the woman’s absence from the shanty the place gets afire, and Florence barely is rescued by Captain Ross. The following day, Ross traps the Italian in a dramatic fashion at the top of the aqueduct, where a fight ensues in which the captain risks his life. It is Pietro, however, who makes the misstep, which sends him to his death at the bottom of the dam one hundred and seventy-five feet below. Florence forgives her lover.”
