Left alone Mark began to think over the situation. His recognition of his unprincipled acquaintance of the Fifth Avenue stage convinced him that some fraudulent scheme was being carried out. Mrs. Montgomery was probably a confederate of the young man who had just left the room.
"Is he going up-stairs or down?" thought Mark.
He listened, and thought he heard the front door open and shut. It occurred to him to open the door of the chamber and look down-stairs.
He started to do this, but to his surprise found that the door was fastened in some way. He had not heard a key turned in the lock. Possibly there was an outside bolt.
"What object can they have in keeping me a prisoner?" he asked.
Should he ring the bell and summon a servant? If he did so, he would have to leave the house in a state of uncertainty. No! he decided to wait and let further events throw a light on the mystery.
Meanwhile the young man who had possessed himself of the rings left the house, for it was he who had descended the stairs and gone out into the street. He bent his steps to the nearest pawnshop on Eighth Avenue, and taking out one of the boxes, said in a nonchalant voice:
"What will you loan me on this magnificent diamond ring?"
The pawnbroker took the box, and drawing out the ring held it up in the best light. He examined it through a magnifying glass, and a gleam of intelligence flashed in his face.
He returned to the counter, and scrutinizing the young man who had presented it asked in a matter-of-fact tone, "What do you want to borrow on the ring, my friend?"
"Two hundred dollars," answered the customer promptly.
"Humph!" said the pawnbroker with an amused smile, "two hundred dollars is a large sum of money."
"Yes, but the ring cost three hundred and fifty dollars. I am asking a little more than half price."
"So! the ring cost three hundred and fifty dollars! Did you pay that price for it?"
"No, the ring does not belong to me."
"Then to whom does it belong?"
"To my aunt, Mrs. Philip Montgomery."
"I do not know the lady. Does she live in the city?"
"No, she lives in Buffalo."
"And she sent the ring to you?"
"Yes, she sent it to me. She is in want of a little money, and did not like to ask her husband for it, for he might not be pleased. So she wants to borrow money on this ring which was given her by her brother at the time of her marriage."
"So, so! And your aunt would like me to lend her two hundred dollars on the ring?"
"Yes, sir."
"I think you will have to carry it to some other pawnbroker, my friend!"
"I don't mind taking a little less," said the young man, who was anxious for more than one reason to realize on the ring at once.
"How much now do you call a little less?"
"Well, say a hundred and seventy-five dollars. Probably my aunt will be able to redeem it in a few weeks."
"If I give you a hundred and seventy-five dollars," laughed the pawnbroker, "I think your aunt will let me keep it for good."
"As to that," said the young man impatiently, "I can make no promises. How much will you give on it?"
"I might give you a dollar and a half," answered the pawnbroker composedly.
"A dollar and a half!" exclaimed the young man, clutching at the counter for support. "A dollar and a half on this magnificent diamond ring, for which my aunt paid three hundred and fifty dollars! What do you mean?"
"I mean not to be cheated, my friend. How much do you think this magnificent ring is worth?"
"I have told you what it cost."
"My friend, you are very much mistaken. The ring cost only three dollars or three and a half."
"What do you mean?" gasped the visitor, turning pale.
"I mean that it is not diamond, but paste."
"But – it came from a jeweler of great reputation. Surely you have heard of Mr. Henry Swan."
"Yes, I have heard of Mr. Swan. If you will bring him here, and he will say that the diamond is real, I will see if I can't give you more."
"Wait!" said the customer hurriedly, drawing out the other casket. "Look at this ring, and tell me what it is worth."
The pawnbroker took it to the window and examined it attentively.
"That may be worth four dollars," he answered, after a brief pause.
"And is this stone false also?"
"Yes, my friend."
"Then I won't pawn either. Here, give me back both rings."
"Here they are."
"I am afraid you are not a good judge of diamonds. I am sure they are real."
"Go somewhere else, my friend, and satisfy yourself. If you can find any one in my line who will give you five dollars for either, you had better take it and call yourself a fortunate man. Will you leave your name?"
"My name is Hamilton Schuyler, and I live on Second Avenue."
"It is a very good name, my friend. I think you must belong to the Four Hundred."
"I do," answered Schuyler haughtily.
