"In the Thirtieth street station-house, sir," she briefly responded.
"Infamous!" exclaimed the young man, in great excitement. "And has she been in that vile place since Saturday evening?"
"She has, sir; but not with the common lot; the matron has been very good to her, sir, and gave her a bed in her own room," the woman explained.
"Blessed be the matron!" was Royal Bryant's inward comment. Then, turning again to his companion, he inquired.
"What is your name, if you please, madam?"
"Kate O'Brien, at your service, sir."
"Thank you; and do you live near Miss Allandale?"
"Jist forninst her, sir—on the same floor, across the hall."
"She writes that her mother is very ill," proceeded the young man, referring again to the letter.
"Whisht, sir; the poor lady's dyin', sir," said Kate in a tone of awe.
"Dying!" exclaimed Royal Bryant, aghast.
"Yes, sir; she has consumption; and just afther the officer—bad luck to 'im!—took the young lady away, she had a bad coughin' spell, and burst a blood-vessel, and she has been failin' ever since," the woman explained, with trembling lips.
"Who is with Mrs. Allandale now?" questioned Mr. Bryant, with a look of deep anxiety.
"The docthor, sir; he promised to stay wid her till I come back."
"Well, then, Mrs. O'Brien, if you will be good enough to hurry back and care for Mrs. Allandale, I will go at once to her daughter; and I am very sure that I can secure her release within a short time. Tell her mother so, and that I will send her home immediately upon her release."
"Bless yer kind heart!" cried the woman, heartily, and she hurried away to take the blessed news to Edith's fast-failing mother.
The moment the door closed after her, Royal Bryant seized his overcoat and began to put it on again, his face aflame with mingled indignation and mortification.
"In a common city lock-up for the crime of passing counterfeit money!" he muttered, hoarsely. "And to think that I brought such a fate upon her!—I, who would suffer torture to save her a pang. Two nights and an endless day, and her mother dying at home!—how she must have suffered! I could go down upon my knees to ask her pardon, and yet I cannot understand it. That money came directly from the bank into my possession."
He was just fastening the last button of his coat when there came a knock upon his door.
"Come in," he said, but frowning with impatience at the unwelcome interruption and the probable detention which it portended.
An instant later a rather common-looking man, of perhaps forty years, entered the room.
"Ah, Mr. Knowles! good-morning, good-morning," said young Bryant, with his habitual cordiality. "What can I do for you to-day?"
"I—I have called to pay an installment upon what I owe you, Mr. Bryant," the man responded, flushing slightly beneath the genial glance of the lawyer.
"Ah, yes; I had forgotten that this was the date for the payment. I hope, however, that you are not inconveniencing yourself in making it to-day," remarked the young lawyer, as he observed that his client was paler than usual and wore an anxious, care-worn expression.
"There is nothing that inconveniences me more than debt," the man evasively replied, but quickly repressing a sigh, as he drew forth a well-worn purse, while his companion saw that his lips trembled slightly as he said it.
Opening the purse, Mr. Knowles produced a small coin and extended it to the lawyer.
It was a five-dollar gold-piece.
Mr. Bryant took it mechanically, and thanked him; but at the same time, feeling a strange reluctance in so doing, for he was sure the man needed the money for his personal necessities, while his small claim against him for advice rendered a few weeks previous could wait well enough, and he would never miss the amount.
He experienced a sense of delicacy, however, about giving expression to the thought, for he knew the gentleman to be both proud and sensitive, and he did not wish to wound him by assuming that he was unable to make the payment that had become due.
He stood awkwardly fingering the money and gazing absently down upon it as these thoughts flitted through his mind, and thinking, too, that it was somewhat singular that Mr. Knowles should have paid him in gold coin and of the very same denomination as he had given Edith less than forty-eight hours previous, and which had been the means of causing her such deep trouble.
Almost unconsciously, he turned the money over, his glance still riveted upon it.
As he did so he gave a violent start which caused his companion to regard him curiously.
"Great Scott!" he exclaimed, in vehement excitement, as he bent to examine the coin more closely, "this is the strangest thing that ever happened to me in all my experience!"
CHAPTER IV.
A MYSTERY EXPLAINED.
Mr. Knowles regarded his companion with undisguised astonishment.
"Is there anything wrong about the money?" he inquired, a gleam of anxiety in his eyes.
"Pardon me," said Royal Bryant, flushing, as he was thus recalled to himself; "you are justified in asking the question, and I trust you will not regard me as impertinently inquisitive if I inquire if you can remember from whom you received this piece of money."
"Certainly I remember," Mr. Knowles replied, but flushing painfully in his turn at the question.
"Will you kindly tell me the name of the person from whom you took it?"
Mr. Knowles appeared even more embarrassed than before, and hesitated about replying.
"I have a special and personal reason for asking you," Mr. Bryant continued. "See!" he added, holding the gold-piece before him where the light struck full upon it, "you perceive this coin is marked," and he pointed out some vertical scratches which had been made just inside the margin. "I made those marks myself."
"Can that be possible!" exclaimed his companion, astonished.
"Yes. This very piece of money was in my possession as late as five o'clock last Saturday afternoon."
"I cannot understand," said Mr. Knowles, looking mystified.
"Let me explain," returned Mr. Bryant. "I owed my copyist exactly five dollars, and, having nothing smaller in bills than tens, I was obliged to pay her with this coin. While she was getting ready to leave the office, I sat toying with it and scratched it, as you see, with the point of my penknife; then I gave it to Miss Allandale, and thought no more about the matter. But just before you came in this morning, I received a note from her saying she had been arrested for passing the coin with which I had paid her, it having been declared counterfeit, and she begged me to come at once to her assistance and try to prove her innocence. I was just on the point of doing so when you called."
"What a very singular circumstance," Mr. Knowles remarked, reflectively. "It appears all the more so to me from the fact that I also received this piece of money no later than seven o'clock on last Saturday evening."
"You amaze me!" exclaimed Mr. Bryant. "Pray explain to me how you came by it—it may help to solve this very perplexing mystery, for I am confident that the coin is genuine, in spite of the trouble it has brought upon Miss Allandale."
"Yes, I will be frank with you," his companion returned, but flushing again, "and tell you that, in order to make this payment to
