Edited by CHICKERING CARTER. CHAPTER I. A TRAGEDY OF THE STAGE. The members of Nick Carter’s household all happened to meet at the breakfast table that morning--a rather unusual circumstance. The famous New York detective sat at the head of the table. Ranged about it were Chick Carter, his leading assistant; Patsy Garvan, and the latter’s young wife, Adelina, and Ida Jones, Nick’s beautiful woman assistant. It was the latter who held the attention of her companions at that moment. She was a little late, and had just seated herself. Her flushed cheeks and sparkling eyes gave no hint that she had reached the house--they all shared the detective’s hospitable roof--a little after three o’clock that morning. “You good people certainly missed a sensation last night,” she declared. “It was the strangest thing--and one of the most pitiable I ever beheld!” Nick, who had been glancing at his favorite newspaper, looked up. “What do you mean?” he asked. It was Ida’s turn to show surprise. “Is it possible you don’t know, any of you?” she demanded, looking around the table. “Haven’t you read of Helga Lund’s breakdown, or whatever it was?” Helga Lund, the great Swedish actress, who was electrifying New York that season in a powerful play, “The Daughters of Men,” had consented, in response to many requests, to give a special midnight performance, in order that the many actors and actresses in the city might have an opportunity to see her in her most successful rôle at an hour which would not conflict with their own performances.
