But Frank did not laugh; instead, to the wonderment of the Indian, he betrayed both consternation and dismay.
"Are you sure of this, Joe?" he demanded. "How long had the girl been missing when you left Holbrook?"
"The sun had slept once."
"By which you mean that one night had passed?"
"Ugh!"
"Then this is serious, indeed! Something most unfortunate has happened, or June Arlington would not be missing overnight. Boys, prepare at once to start for Holbrook! Get ready to mount and ride as fast as horseflesh can carry us; We'll start at the earliest moment possible!"
Crowfoot arose, a look of wonderment in his dark eyes. He reached out and grasped Frank's arm.
"What would Strong Heart do?" he asked.
"I'm going to Holbrook hotfoot," was the answer. "I'm going to find out, if possible, what has happened to June Arlington, and I shall do my best to return her to her mother, if she has not already returned when I reach there."
