The quadrangle was almost deserted at the time. Andy hurried down and ran over to where Link was standing. The student caught the gleam of something on the wrist of his friend. It was a steel handcuff!

“What—what’s up, Link?” Andy gasped.

“Why, Mr. Blair—I don’t know. This man—he says he’s a detective, and——”

“So I am a detective, and I don’t want any of your funny work!” was the snappish retort. “There’s my badge,” and it was flashed from under the armhole of the man’s vest, being fastened to his suspenders, where most plain-clothes men carry their official emblem.

“A detective!” gasped Andy. “What’s the matter? Why do you want Link Bardon?”

“We want him because he’s accused of being the quadrangle thief!” was the unexpected answer. “Stand aside now, I’m going to take him to the station house!”
