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.

The date had been set for the night before, and, since it was not to be exclusively a performance for professionals, the manager of the theater, who was a friend of Nick Carter’s, had presented the detective with a box.

Much to Nick’s regret, however, and that of his male assistants, an emergency had prevented them from attending. To cap the climax, Adelina Garvan had not been feeling well, so decided not to go. Consequently, Ida Jones had occupied the box with several of her friends.

Nick shook his head in response to his pretty assistant’s question.
