The young lady looked very much surprised.
"She is my mother," she replied. "But how in the world do you know of her?"
"I will tell you later," answered Mark.
He felt that it wouldn't be wise to mention the commission, or let any one know that he had a diamond ring in charge.
"Are you going directly to Cleveland, Miss Loring?"
"Yes, but about thirty miles this side I have a young niece at a boarding school. She will join me on the train, and will expect me to pay her railroad fare. But for that, the loss of the money would have entailed no inconvenience."
Mark drew from his pocket book a five-dollar bill and passed it to Miss Loring.
"But how can I return this to you?" she asked.
"I will call at your house. I am going to Cleveland also."
"Do so. Here is my card."
She took out a small card and tendered it to Mark. On it was inscribed:
Miss Florence Loring
No. 1001½ Euclid Avenue
"Inquire for me when you call!" she said.
"Thank you."
"It seems so strange that you should know my mother," she continued evidently feeling curious.
Mark smiled.
"You will know in time," he said. "If we were alone I would tell you now."
Here there was a stop at some station, and a shabby and dirty-looking man entered the car.
There was but one seat vacant, the one next to Florence Loring.
Mark hastily rose and sat down in it.
"I thought," he said apologetically, "you might prefer me to the man who has just entered the car."
"By all means," she answered with a bright smile. "I prefer you also to the clerical gentleman who rode with me earlier."
"Thank you. When your niece joins you I will vacate the seat in her favor."
Florence Loring was perhaps nineteen, three years older than Mark. She looked upon him quite as a boy, and therefore felt under no constraint.
"Do you come from New York?" she asked.
"Yes."
"You seem young to travel alone."
"I don't think you can be much older than I," said Mark.
"Mercy! I feel ever so much older. I feel old enough to be your aunt."
"I shouldn't mind having you for an aunt," returned Mark.
"On the whole, though, it might prove to be too much of a responsibility. You may be very hard to manage."
"Do you mind my calling you aunt?"
"Well, perhaps it might make me appear too venerable."
"Did you notice, Miss Loring, whether your clerical friend left the cars when he left the seat?"
"No; I didn't feel any particular interest in him, and did not give him a second thought."
"Perhaps he may still be on the train. I have a great mind to go and see."
"I don't think it would do any good. We could not prove that he took my purse."
"If you will excuse me for five minutes I will make a search."
Mark went through the next car and entered the second one, which was a smoking car. He looked about him, and in a seat about the middle of the car he saw the man of whom he was in search. He recognized him by his white tie and his red nose. He was smoking a cigar and gazing out of the car window.
The seat beside him being vacant Mark went forward and sat down in it.
The gentleman with the white tie glanced at him carelessly, but did not appear to think Mark was worthy of attention. He changed his mind when Mark said in a low voice:
"Please give me the purse which you took from a young lady in the second car back."
CHAPTER XVI
MARK AS A DETECTIVE
The adventurer turned swiftly when he heard Mark's startling question. He seemed astounded at the boy's audacity.
"What did you say?" he demanded with hauteur.
"I asked you to return the purse which you took from a young lady in the second car back," repeated Mark calmly.
"Boy," said the false minister, "you must be insane or drunk."
"I don't think I am either," returned Mark.
