you want to keep out of trouble you will help us to hunt up my brother."
"That is just what you had better do, sir," added Frank.
"And who are you?" demanded the irate landlord.
"I am Frank Harrington, son of Senator Harrington."
At this unexpected announcement the jaw of the landlord dropped perceptibly. "Why—er—I didn't know you were Senator Harrington's son," he stammered.
"I think if you wish to keep out of trouble you had best aid us all you can. The young man we are after came in here a short while ago and has utterly disappeared. I am afraid he has met with foul play."
"But Mr. Arson and Mr. Noble are gone."
"Is that the names they were known under?"
"Yes."
"Their right names are Girk and Baxter. They left the building just before we came up."
"What was your brother doing here?" asked Caleb Yates in a calmer tone.
"He was not my brother, but my warmest friend. He was tracking the short man, the fellow whose name is Girk. Girk once robbed him of his watch."
