A cabman was readily found, and inside of a few minutes they were on their way to the Philip Chesterfield estate. From the driver they learned that this Chesterfield was an old man, rather peculiar in his ways, and that he entertained visitors but seldom.
"It would be queer for Nick Jasniff to visit such a man," remarked Dave.
"But I don"t want to let any chance of locating him slip by."
"Nick may be glad enough to get a roof over his head, if his money is gone," answered Roger.
The cab presently turned up a side road and approached the stone wall of a fair-sized estate, the mansion of which stood back in a patch of old trees. As they entered the gateway Dave saw a door open and a boy came out on a veranda.
"There he is!" he gasped. "There is Nick now!"
"You"re right!" exclaimed the senator"s son. "This is luck, and no mistake."
As the cab came closer Nick Jasniff gazed at it curiously, to see whom it might contain. Not to be recognized too quickly, Dave kept his face averted and cautioned his chum to do the same.
"Say! I say----" began the youth who had run away, when Dave leaped out and confronted him. "Whe--where did you come from?"
"From Oak Hall," answered Dave, coolly. "I fancy you didn"t expect to see me so soon, Jasniff."
"Humph!" The runaway boy did not know what to say. "I--er---- Been following me up, I suppose?"
"I have."
"You didn"t expect me, did you?" put in Roger, with a grin.
"I didn"t," growled Nick Jasniff. "Any more?" and he gazed anxiously into the cab, half expecting an officer of the law to put in an appearance.
"No more just now," said Dave, with peculiar emphasis.
"What do you want?" Jasniff was gradually regaining his self-possession.
"I want a whole lot of things," answered Dave. "Do you want to do your talking here or in the house?" And he glanced at the cab driver, who was staring at the boys with his mouth open in curiosity.
"You can come in, if you wish," was the awkward answer; and Nick Jasniff led the way into the old mansion, which was semi-dark and not more than half warmed. "Do you know who lives here?" he continued.
"Your relative, Philip Chesterfield," answered Roger.
"Humph! He"s a great-uncle of mine and very old. He is down with gout.
Come into the library. We needn"t disturb him."
They filed into the apartment mentioned, a long, low room, the walls of which were lined with shelves filled with musty volumes. Dave kept his eyes on Jasniff, and this the runaway noticed.
"Think I"m going to skip?" he queried, sourly.
"I"ll not give you the chance," was the ready answer.
"You think you"ve got me foul, don"t you?"
"Doesn"t it look like it?"
"You can"t make me go back to the United States."
"Perhaps I can."
"My folks have settled up that Pud Frodel affair for me--did it only a few days ago."
"But they didn"t settle up with Mrs. Clever. She was swindled out of some board money."
"I--er--I was going to send her that money to-day."
"Then you had better pay me, for I settled the account," answered Dave.
"But let us drop this talk for the present, Jasniff. I want you to tell me all you know about my father and my sister."
"Humph! I haven"t got to tell you anything if I don"t want to."
"Yes, you have got to!" cried Dave. A dangerous gleam came into his eyes. "Out with it at once. Where is my father?"
"See here, Porter, I don"t propose to be bullied. I----"
"You answer my question, Nick Jasniff. If you don"t I"ll call in an officer at once and have you placed under arrest."
"You can"t do it."
"I can and will. If I can"t have you held on one charge I"ll have you held on another. I want the truth from you, and I want it right away."
Dave had followed Nick Jasniff to a window, and faced the runaway with such sternness and determination that the latter cowed before him.
"I--er--that is, your father went north, last week."
"Where to?"
"He said he was going to Christiania, Norway."
"Christiania, Norway?" repeated Dave. He knew there was such a place, but that was all. "What for?"
"Oh, he was interested in an expedition that was going to the upper interior--some kind of a scientific expedition, I think. He was full of it--said they hoped to make all kinds of discoveries."
"Whose expedition was it?"
"It was gotten up by two men named Lapham and Hausermann."
"I read about that expedition!" cried Roger. "There was an account of it in this morning"s _Times_."
"When was it to start?" asked Dave, anxiously.
"I don"t know."
"Do you know, Jasniff?"
