"What's up ?" "Hallam and I are going for a brief walk." Then, stepping back into the front room, Darrin nodded to his classmate, who followed him outside.
"Just come along, and say nothing about the matter on the street," requested Dave.

"It might be overheard." "Where are you going ?" questioned Hallam wonderingly.
"Wait and see, please." From Chow Hop's wretched establishment it was not far to the other building that Dave had in mind as a destination.
But when they arrived, and stood at the foot of the steps, Hallam clutched Darrin's arm, holding him back.
"Why, see here, this is the police station!" "I know it," Dave replied calmly.
"But see here, you're not--" "I'm not going to drag you into anything that you'd object to," Darrin continued.

"Come along; all I want you for is as a witness to what I am going to say." "Don't do it, old fel--" "I've thought that over, and I feel that I must," replied Dave firmly.
"Come along.

Don't attract attention by standing here arguing." In another instant the two midshipmen were going swiftly up the steps.
The chief of police received his two callers courteously.

Dave told the official how their attention had been called to the fact that one of their number was in an opium joint.
