"Margaret A. Langmore," he murmured. "Those initials are hers. If the shirtwaist was hers, how did that fellow get possession of it? And did he place it here or find it here?"
Drying the garment as much as possible, he placed it in his pocket, and continued his search around the vicinity. He spent fully an hour in the locality, and then walked back the way he had come, and into the mansion. There he found Thomas Ostrello in conversation with the policeman.
"It is a terrible blow to me," the commercial traveler was saying. "And to think I was here just the day before it happened! If I had remained here over night, it might not have occurred at all!"
"Well, that's the way things happen," answered the policeman. "Once I was at one end of my beat when a thief broke into a store at the other end and stole sixteen dollars and two hams."
"And I suppose they blamed you for it."
"Sure they did. I was laid off for a week, without pay. If anything happens it is always the poor copper who is to blame."
"Well, the family are not blaming you for this."
"They can't—especially as they've got the person who did the deed."
At this Thomas Ostrello shrugged his shoulders.
"I don't know about that."
"You don't?"
"No. I'd hate to believe any girl could do such a fearful thing as this." The commercial traveler paused. "I'm going to take a look around. I suppose it's all right."
"Certainly, Mr. Ostrello," answered the policeman, and then the commercial man stepped into the library, closing the door after him.
Adam Adams had passed into the dining room, just back of the library, but had heard what was said. Now, looking through the doorway, which had a sliding door and a heavy curtain, the latter partly drawn, he saw the man glance around hurriedly, moving from one object to another in the library. He looked under the table and the chairs, in the corners, and even into the various bookcases. Then he came and knelt down before the safe, and tried the knob of the combination half a dozen times.
"He is more than ordinarily interested," reasoned the detective. "But then it was his own mother who was murdered."
The commercial man continued his search until he had covered every object in the room several times. He even looked behind the pictures, and into the drawer of the table, something which had escaped the coroner's eye when sealing up the desk. Adam Adams saw him shake his head in despair. He took a turn up and down the apartment and clenched his hands nervously.
"Gone!" he muttered to himself. "What could have become of it?"
He drew from his pocket a notebook he carried, and studied several items carefully. A long sigh escaped from his lips as he restored the notebook to his pocket.
As the commercial traveler moved toward the dining room, the detective stepped into a side apartment, used in the winter as a conservatory. He saw Thomas Ostrello make an examination of several places, including a sideboard. Then the woman who had been placed in charge of the downstairs portion of the mansion entered.
"Won't you have a bite to eat, Mr. Ostrello?" she asked.
"Perhaps so, later on. I do not feel like eating now. Can I take a look at my mother's room?"
"Why, yes. I suppose you know where it is?"
"Certainly; I often visited her there when she was not feeling well."
He passed out without another word, and was soon mounting the heavily-carpeted stairs. Once in the room, he closed the door tightly. Coming up softly after him, Adam Adams tried the door and found it locked. More interested than ever, the detective, just avoiding Mrs. Morse, who was passing through the hallway, slipped into the adjoining room, and finding, as he had imagined, a door between the two, applied his eye to the keyhole.
This might mean nothing, and it might mean everything. He saw Mrs. Langmore's son moving around the dressing room precisely as he had moved around the library. He heard the bureau drawers opened and shut, and then heard the squeak of a small writing desk that stood in a corner, as the leaf was turned down. Then came a rattle of papers and a sudden subdued exclamation. The desk was closed again, and the man came out of the room, leaving the hall door partly open.
"Whatever he was looking for, he must have found it," reasoned the detective. "Now, what was it?"
He waited in the hallway and heard Thomas Ostrello enter the dining room. A minute later came the rattle of dishes. Then Mrs. Morse confronted him.
"Back again, I see," she said rather sharply.
"Yes; I wish to have another talk with Miss Langmore," he returned, and, brushing her aside, knocked on the girl's door, and was admitted. The woman pursed up her lips.
"How very important some of those city lawyers are," she muttered. "Think they know it all, I guess. Well, he'll have a job clearing her, if what Coroner Busby says is true."
"Oh, I did not know you were coming back!" exclaimed Margaret. "Has anything happened?"
"I want to know something about this, Miss Langmore," and he brought out the torn and wet shirtwaist. "Is it yours?"
"Oh, certainly; but where did it come from? And it is all torn, too!
It was almost new when I had it on last!"
"When was that?"
The girl thought for a moment, and then turned pale.
"On the morning that—that—"
"That the tragedy occurred?"
"Yes. I don't know what made me put it on, but I did."
"And when did you take it off?"
"Why, let me see. Some time in the afternoon, I think. I—I fainted, and it got dirty, and so I put on another and threw this in the clothes closet."
"Are you certain you put it in the clothes closet?"
"Positive. Where did you find it?"
"Never mind that just now. Do you keep your shoes in that closet?"
"I do. But why—"
"Will you kindly see if all of your shoes are there?"
The girl ran over, opened the closet door, and began an immediate examination.
"One pair is missing—a pair I use a great deal, too," she said a minute later. "Oh, Mr. Adams, what does this mean?"
"I don't know—yet. While you are at it, you might let me know if anything else is missing."
Margaret began a close examination of everything in the closet, the detective watching her as keenly as he had before.
"She is either innocent, or else the greatest actress I've ever met," was his mental conclusion. "I think her innocent, but the best of us get tripped up at times. If she is innocent, that evidence was manufactured to prove her guilty. If only I had followed that man up! I might have learned something worth knowing."
"Nothing else seems to be missing," announced the girl, at length.
"Very well; then don't waste time by searching further. By the way, did you know Mr. Thomas Ostrello had arrived?"
"Yes; I told Raymond to telegraph for him. He used to call quite often to see his mother."
"What about the other son—Dick?"
"I do not know where he is."
"Didn't he come here?"
"He came once. But he is a dissipated young man, and I do not think my stepmother
