“Was that the lad?” demanded Bob.

“I’m sure of it,” Jim nodded.

“Could you describe the plane?” Carlos wanted to know.

“I could do that,” Jim answered, then he frowned thoughtfully. “If he’s a member of the gang we’ve been having all the fireworks with he or some of his gang may try to waylay us on the way home. Could the information be given to the police confidentially?”

“That shall be attended to, my boy. You early birds do manage to—”

“Gobble the worms,” Bob suggested.

CHAPTER IV

A DISTRESS CALL

Immediately after breakfast the Sky Buddies, Carlos and Senor de Castro went to the office of the Detention Bureau where, without being observed themselves, they took a good look at several men held under suspicion as implicated in the murder of Ollie Boome. Although the three boys were mighty careful in the scrutinizing they agreed they had never seen any of the prisoners before. Then Jim wrote a detailed description of the airplane they had seen hovering over Amy-Ran fortress, also as good an account as possible of the pilot, for police broadcasting through North and South America. Where and how this information was obtained was to be kept a strict secret. That was arranged by Senor de Castro without difficulty.

“Any time you young travelers desire to pay us a visit and go through the prisons, we shall be most delighted to have the pleasure of escorting you,” the official promised elaborately. The Flying Buddies had caught glimpses of the pens, cells, yards, high wall and guards which were sufficient to satisfy their natural curiosity.
