“Don’t know,” admitted Ned. “But you can see for yourself. The door’s locked.”
“Maybe the catch slipped by mistake when the captain went out,” suggested Frank. “Give him a call, or pound on the wall to attract attention.”
“Let me give the door another try,” Bart said. “No use making a false alarm. Maybe it’s only stuck.”
But it was too evident that the portal was locked. The knob turned freely, but the bolt was shot and effectually made the boys prisoners.
“Shall I pound on the door?” asked Bart.
“Let’s see if there isn’t another way out,” suggested Ned.
They looked all around the room. It was about ten feet square, and, aside from the table, chairs and lamp contained no furniture or furnishings.
“There isn’t even a window,” said Frank.
“What’s that up there?” inquired Fenn, pointing to some sort of an opening near the ceiling.
