“It seems queer to me,” Dick spoke. “I’ve thought a lot about it. The fellow who played ghost must be searching for something. What can it be?”
“The emeralds?”
“But he was there before they were lost, Dick,” Larry objected.
“That’s so, Larry.”
“Here’s something that just came to me.” Sandy bent forward in the lounging chair. “Nothing has happened at night, for ten days. But all that time, Mr. Whiteside has been on the ‘day watch,’ as he calls it.”
“Golly-gracious!” Larry exclaimed. “Do you think?——”
“When Jeff flew us there, the first time, there seemed to be somebody in that hangar when we started in,” Dick added to Sandy’s idea.
“You’re right,” Sandy admitted. “By the way, Jeff is back at Bennett Field, taking up passengers for hire again.”
“I’m not worrying about Jeff.” Larry was caught by the suspicious action of their “detective” in taking the day watch while nothing occurred at night.
“What do you think of going out there to the hangar now?” he asked.
