“But, Violet, I have never doubted how my father came to his death. He was no doubt on the track of my betrayer. He found him, and in an altercation was murdered by the man I afterward found was Harold Castello, a fast young man of Chicago. But I could not bring home his guilt to him, although I have been on his track ever since my recovery. But now all is different, dear, for you saw him commit the murder. You can help me to bring it home to him.” CHAPTER XXXIII. AN ADMIRING STRANGER. Violet had been sobbing softly at the recital of her friend’s sorrows, but now she lifted her fair head, and dashing the tears from her eyes, answered, tenderly: “I will tell you the whole harrowing story, Lena, for I was indeed the horrified witness of your poor father’s death, and the memory of that scene will never leave me while life lasts!” Lena pressed her cold little hand and waited anxiously for her to begin. “I must tell you first how I came to be in Chicago at that time,” said Violet. “You see, I was at boarding-school, and last June our lady principal and her senior class formed a party to attend the World’s Fair together for a stay of ten days or so. I wrote to grandpapa, and he readily gave his consent to the plan and inclosed me a generous check for expenses. On the first of June our party, consisting of Mrs. Maynard, our teacher, and ten young girls, arrived in Chicago, full of joyous anticipations over the wonderful sights we were to see. “As you have been to the Fair yourself, my dear Lena, I need not dwell on its glories, but only remind you that among the hurrying throngs that filled the immense palaces on every hand, it was utterly impossible for such a large party to keep close together. Mrs. Maynard realized this the first day, and directed her young charges that in the event of getting separated from each other, we should all meet her at the closing hour at the Virginia Building, in order to go home together. We found this plan worked nicely, affording each a better opportunity to inspect the buildings that appealed most strongly to our individual tastes. “On the ninth day of our attendance at the Fair we separated into parties. Mrs. Maynard and three girls decided to spend that day at the Woman’s Building, two girls went to the Midway Plaisance, two more to the Electric Building, and two more to the Building of Liberal Arts and Manufactures. I found myself alone in the eager desire for a whole day in the magnificent Art Gallery. “There seemed no possible harm in leaving me there alone, and Mrs. Maynard consented to my wish, saying, kindly: “‘I can trust you, Violet, I know, to meet me at the Virginia State Building at six o’clock.’
