  Both boys were wondering, too, about a certain surprise their father had hinted might be ready for them upon his return.
  Waiting with Frank and Joe for Mr. Hardy's arrival was their best friend Chet Morton. "Your dad's cases are always exciting—and dangerous," the plump, ruddy-faced boy remarked. "Do you think he'll give you a chance to help out on this one?"
  Frank and Joe chuckled, knowing that Chet, despite his penchant for taking things easy and avoiding unnecessary risks, would stick by them through any peril.

  Frank laughed. "Its signaling days are over." "Sure hope so," Chet declared firmly. "No more mysteries for a while, please!"
  His words proved to be true. Sooner than even the Hardy boys expected, they were called upon to solve the mystery of **THE MISSING CHUMS.**
  Now Joe turned to their plump friend. "Good thing you bought that microscope, Chet. We started to look for nature specimens and dug up the old mill's secret!"
