the criminals may be?"

"I think I could make a pretty close guess, Mr. Spicer."

"I should like to know which way your suspicions point."

"Well, sir, it is my decided opinion that Margaret Ernst was murdered by parties in this house."

"Oh-ho! that's it, eh? Well, I think I see your line of argument, sir, and I must say you reason shrewdly."

"I am confident that when the truth is known you will find I am right."

"I shouldn't at all wonder."

"At least," added the financial manager, "you will find that some one in this house is seriously implicated, mark that, Mr. Spicer."

"I will remember what you say." Then in another tone:

"Let's see, how old was she?"

"Her age has been stated as seventy-two. I think she was nearer seventy-four or seventy-five."

"She was from Germany?"

"Yes, from Oxburg, in Bavaria."

"She had made a will?"

"Yes."

"To whom did she leave her property?"

"One half to her own relatives in the old country, and the rest to the relatives of her last husband."

"He died about ten years ago?"

"Who, John Ernst?"

"Yes."

"Nearer twelve, I should say."

"He had been in this country some time?"

"Yes; he served in the Union army through the late war."

"What was her maiden name?"

"Margaret Tepley."

"You heard what Bollmann's detectives said. Do you think as they do, that there was no intention to kill her?"

"Nonsense! She was deliberately murdered. The back of her head was pounded against the arm of that sofa, and afterward she was smothered with a pillow. No intention to kill her? Pshaw! the poor old lame woman attempted to make a fight of it. Why, sir, she called out as loud as she could. Her voice was heard distinctly by people in the house."

"So? You are quite sure of what you say?"

"Believe me. I know what I am talking about, Mr. Spicer."

"I must see some of the people of the house."

"Do so. Go into the matter thoroughly."

"I generally do, Mr. Zunder."

"I know that; hence, I have faith in you. And a word in your ear, Mr. Spicer. Your work shall be well paid for. I will see to that. As you can easily understand, I feel more than an ordinary interest in this case."

"I understand. And you can depend on me, and those associated with me, to do our level best to get at the exact truth in this cold-blooded and cowardly affair." And a moment later, after whispering to Stricket and George Morgan, Old Spicer left the basement.

CHAPTER IV.

OLD SPICER CONTINUES HIS INVESTIGATIONS.—THE SECRET VAULT.

After a word or two with Coroner Mix, who was standing in the outer hall, Old Spicer ascended to the main floor of the house, where he questioned Otto Webber and his wife, and then climbing another flight of stairs, knocked at the door of John Neustrom's apartments.

The door was opened by a young woman of perhaps twenty summers, and the caller was invited to enter.

There was another person in the room—a woman—who was seated by the window.

"Mrs. Neustrom, if I am not mistaken?" said the detective, in an inquiring tone, as his eyes rested on this lady.

"Yes; I am Mrs. Neustrom," she said.

"And this is your charming niece, Miss Minnie?"

"Yes, the girl is my niece."

"I have called, Mrs. Neustrom, to put a few questions to Miss Minnie with regard to what she saw and heard last night at, I think, somewhere between eleven and twelve o'clock;" and as he had not been asked to sit down, Old Spicer now quietly seated himself on his own accord.

"I am sorry, sir," said Mrs. Neustrom, in a tone of decision; "but it will be impossible for her to answer your questions."

"Why so?"

"She has been cautioned not to speak on the subject to any one."

"By whom has she been cautioned?"

"By two, or more, of the officers of the law."

"Which ones?"

"Well, the chief, for one."

"And who else?"

"A detective."

"I suppose you know something of the law governing such cases, Mrs. Neustrom?"

"I know very little about the matter, sir."

"I am sorry to hear that."

"If Mr. Neustrom were home, he might know. He's pretty well posted."

"Then he's not in the house at present?"

"No, sir; he went out a little while ago with one of the detectives."

"That's very unfortunate. But as it happens, I also am pretty well posted in the law."

"You are?"

"Yes, ma'am, and I assure you, in such cases, the law places unlimited authority in the hands of the coroner."

"It does?"

"Yes, ma'am, and he has ordered me to get Miss Minnie's testimony. I have also the authority of the late Mrs. Ernst's executor to back me. In short, I am employed by these two gentlemen."

"And who may you be, sir?"

"My name is Spicer—Mark Spicer," answered the detective with a polite bow. "It's just possible you may have heard of me before."

"Oh!" exclaimed Minnie Neustrom, eagerly. "Old Spicer! Of course, auntie, I shall tell him everything."

"Why, certainly, my dear," answered her aunt, "especially as it's the law."

Old Spicer smiled quietly, and turning to the young lady, said:

"You saw three strange men hovering round the premises until nearly midnight, I believe?"

"Two, not three, sir," answered Minnie.

"Only two? I understood you said three."

"No, sir; there were only two."

"What first attracted your attention to them, Miss Neustrom?"

"Their loud talking, sir."

"Loud talking, eh? Where were they when you first heard them?"

"In Mrs. Ernst's kitchen, I think."

"How did it happen that you were up so late last night?"

"I had been down-town, and did not reach home until after half-past ten o'clock."

"And you did not go to bed at once when you did reach home?"

"No, sir. Before I retired, auntie, here, asked me to lock the woodshed door."

"Where is your woodshed?"

"In the yard, in the rear of the house; and in order to reach it I was obliged to go down two flights of stairs. You may think it strange, sir, but even while I was obeying the instructions of my aunt a horrible dread that something awful was soon to occur came over me, and my trip to the woodshed was made literally in fear and trembling."

"Then, I take it, you were not long in accomplishing your purpose?"

"No, indeed, it took but a second to bolt the woodshed door, and an additional minute or two for me to retrace my steps."

"And then you went to your window?"

"Yes, sir; for, you see, from the window of my room, a person can look down on the rear apartment windows of the basement. I raised the window, but could not hear the words used in the basement below, although the parties there seemed to be still quarreling with their tongues."

"Were they Germans?" asked Old Spicer.

"No, sir; I am quite positive they were not."

"What makes you so sure about it?"

"Because the indistinct utterances I overheard did not sound at all like those coming from a Teutonic tongue."

"You caught sight of these parties at last, did you not?"

"Yes, sir; just before I went to bed I saw from my window the forms of two men issuing from the basement and prowling in the yard."

"Would you know those men again?"

"Good gracious! no, sir."

"Why not?"

"A heavy fog had settled in the neighborhood, making it impossible for me to obtain a clear view of them, or, indeed, of any objects forty feet away."

"When you found you couldn't make out who they were, what did you do?"

"I went to bed."

"A very wise proceeding, I must confess." Then abruptly:

"Miss Neustrom, I would like to see you alone for a few minutes."

The girl started and looked at her aunt.

That good woman seemed bewildered, and didn't know what to say.

"I
