Morgan never liked to be rough in his methods. He hesitated over forcing himself into the presence of this young woman, and yet he now had an impression that an interview with her was imperative. There was a slight pause, as he ran over in his mind some way to gain his entrance without force.
"Do you know Mr. Marsh downstairs?" he inquired, suddenly, his eyes keeping a keen watch on her face.
"I do not know any of the tenants in the building."
"That's strange," said Morgan, thoughtfully. "I was just talking with Mr. Marsh, and he told me that you knew all about the trouble last night. He suggested that if I would come and see you I could get just the information I wanted."
"I don't know this Mr. Marsh, and I can't understand why he should make such a statement." Surprise was apparent in her voice.
Morgan was quite sure that her surprise was genuine. At the same time his remarks had just the effect he had hoped they would. It brought a new element into the matter and added to the girl's natural curiosity. She opened the door wider, and nodding toward the front room, said, "Step in and tell me what you wish to know."
The room into which Morgan entered was a counterpart of the one across the hall, though as he rapidly observed the furnishings, he was impressed with the greater taste displayed and the homelike atmosphere. A piece of embroidery, on which she had evidently been working, lay on the arm of a chair near the window.
Conjecturing that she would resume her seat in this chair, Morgan seated himself where he could keep his back to the window, while the girl whom he was about to question would directly face the full light. Morgan's guess was correct. The girl went directly to the chair she had left to answer his ring, and taking up her embroidery, picked nervously at its edges, meanwhile watching Morgan expectantly.
Surmising that a direct attempt to question her at once might defeat his purpose, Morgan immediately broke into an account of the previous night's occurrence. As he brought out the various details of what was reported to have taken place, he slyly watched her face. At the end of his recital, he felt convinced that what he told the girl had previously been unknown to her. Moreover, Morgan became sensible of a growing feeling of interest and confidence in the girl. Her sweetness seemed so genuine, her dark blue eyes so frank and honest in the straightforward way they met his.
"It seems very strange that I heard none of the excitement," remarked the girl, when Morgan had finished his story. "I had a rather busy day yesterday with my studies and retired early."
Morgan had decided upon his line of questioning while relating the incidents of the night before.
"May I ask your name?"
"Certainly," she replied. "My name is Atwood."
Morgan, having noticed the absence of a wedding ring, assumed that she was unmarried. Therefore, he said, "Is your mother at home, Miss Atwood?"
A shade of sadness passed over her face. "My mother died some months ago," she replied.
"I am sorry. I know what it is to have a good mother," sympathized Morgan. Then he inquired, "Perhaps your father heard the disturbance?"
"Oh no," she replied. "My father is away."
"He travels?"
"Yes; my father is a salesman."
"For some Chicago house, I suppose."
"No; for a business house in St. Louis. We formerly lived there."
"St. Louis is a pleasant city," commented Morgan. "Still, many people prefer Chicago."
"Oh, I think I should prefer to live in St. Louis, because I have a few friends there," she said. "But I am studying music, and when my mother died, father suggested that I live in Chicago where I could attend a better musical college. Then, too, father could get home more often as he travels in this vicinity."
"I suppose your father travels for some well known St. Louis house?" suggested Morgan.
"Well, really, I don't know the name of his firm," returned the girl. "Business has never held any interest for me."
It struck Morgan as strange that even a girl who did not take an interest in business should be ignorant of the name of the firm by whom her father was employed, yet he seemed to find many things that were contradictory in this girl. The chatty line of conversation he had taken was bringing out information in a manner highly satisfactory to Morgan. He was about to make another comment, that might elicit further facts, when he was interrupted by a question which he had been expecting.
"Tell me," inquired Miss Atwood, a slight color coming to her cheeks, "what this man Marsh said about me."
Morgan was pleased. This gave him an opening for some questioning which he had hesitated to take up before. He wanted to know just how much this girl knew about Marsh. "Don't you really know Mr. Marsh?" he began.
"No," she replied. "I didn't even know there was such a person in the house."
"Well, that is certainly strange. I'm sure that he told me to talk to the young lady on the top floor. Perhaps he meant some young lady who lived across the hall. Still, there doesn't seem to have been anyone there since the trouble."
Miss Atwood smiled. "He could not have meant anyone in that apartment, for I understand it is occupied only by an elderly couple, a Mr. Ames and his wife. I understood father to say that he had heard they were traveling in Europe. I am sure no one has lived there since we have been in this apartment."
"How long have you been here?" asked Morgan.
"Let me see," said Miss Atwood, thoughtfully. "This is almost the end of October, and we have been here since the middle of July. That is a little over three months, isn't it?"
"July," repeated Morgan. "That isn't a renting season. You must rent this apartment furnished."
"We do," she replied, promptly. "Father was too busy to spend any time on moving, so we stored our things in St. Louis and took this apartment."
"Real estate agents have been making lots of money these days. I hear a great many people have to pay them a bonus for finding apartments. I suppose they stuck you that way, too."
"No," returned the girl. "I understand that father rented direct from the tenant. I believe the tenant was a friend of his, or someone he knew in a business way."
The embroidery which had been lying in Miss Atwood's lap had gradually slipped forward and at this moment dropped to the floor. As she reached down to pick it up, Morgan's alert eyes noted a purplish mark on her forearm.
"You seem to have bruised your arm, Miss Atwood," he said, in a tone that was intended to express sympathy.
"Oh, did you notice that mark?" she exclaimed. "That has been puzzling me all day. I awoke suddenly last night with a feeling as if something had bitten me, but almost immediately went to sleep again. During the morning I noticed this mark and the swelling. I can't imagine what could have done it."
"May I look at it?" asked Morgan, as he rose and approached her. "Perhaps I can suggest something."
She extended her arm, and Morgan, taking her hand, drew the arm close to him. He carefully studied the spot. The only time he had ever seen such marks before was on the arms of drug addicts who had not been particularly careful in the application of the hypodermic needle.
"So you think it is a bite of some kind?" asked Morgan, looking keenly at her.
"I can't imagine what else it could be," she replied.
Morgan dropped her hand and looked out of the window for a moment. There was no doubt in his mind that the mark had been made by a hypodermic needle, yet it was the only mark of the kind that he could see on her arm, and therefore would hardly seem to indicate that the girl was a drug fiend. Moreover, there had bean no indication of embarrassment or nervousness in her reference to the mark, as would undoubtedly have been the case had she been addicted to the use of a drug. Morgan realized,
