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, too, that the fresh pink and white skin of this girl, and the bright eyes, could not be maintained if drugs were taken. The case was growing more puzzling every minute. Had the use of a hypodermic needle on this girl anything to do with the supposed tragedy across the hall?
After this discovery, Morgan hesitated to ask further questions at this time, so he turned to the girl again and remarked, simply, "It is possible that some kind of spider bit you in the night. If you have any peroxide in the house, I would suggest that you bathe the spot with it. And now I must be going. If I have your permission, Miss Atwood, I would like to drop in again sometime to let you know about any further discoveries I may make on this case."
"Thank you," she returned. "I shall be interested."
As he turned to say good-bye at the door, she added, apologetically, "I am sorry I had no information to give you."
"Oh, that's all right," Morgan assured her, "I appreciate your courtesy in letting me have this little chat with you." But as he drew the door to after him, Morgan smiled and said to himself, "Poor little girl; you don't realize what a lot of information you have given me."
CHAPTER V
PECULIAR FACTS
When Morgan reached the second floor on his way down, he paused a moment before Marsh's door. So far as he had gone in this case, Morgan was confronted with two factors; the connection of this man with the case, and the bearing which Miss Atwood and her father might have upon it. Without doubt, some singular conditions surrounded the Atwoods, but his knowledge of these was still too vague to give him even a basis for reasoning. On the other hand, the questionable circumstances surrounding the connection of this man Marsh with the case, were very definite, indeed, and though Morgan tried to avoid hasty conclusions, he could not keep back his growing suspicions of Marsh. As he hesitated before Marsh's door, Morgan thought that it moved slightly. Stepping closer and pushing the door gently with an outstretched hand, he found it tightly closed. Yet, he had a feeling that the door had been softly closed after he had stopped on the landing. That decided Morgan. The time was not opportune for an interview with this man. He wanted to obtain some additional facts before taking the step he was now convinced would have to be taken, and so went on down the stairs to carry his investigations further.
Leaving the house, Morgan turned the corner of Lawrence Avenue and entered the alleyway in the rear of the Hillcrest apartments.
Practically all Chicago apartment houses have an outside rear stairway for the use of tradespeople. Usually, this stairway is open so that anything which takes place can be observed from all nearby houses. In this instance the stairway was enclosed, with a door leading to the back porch of each apartment. A person could pass from the alley up to the third floor without being noticed, even by tenants in the building itself.
Morgan instantly noted that an automobile could stand in the alleyway close to the entrance; that a person could come down these stairs unobserved, step into the car and be quietly carried away, disappearing into the general traffic of the streets
