“We’ll leave a note for her that she can read when we are well away,” said Mike. “But we really mustn’t do anything to warn her or anyone else. My word — what a mercy that Paul had that aeroplane for his birthday!”

“When shall we go?” said Paul, his big dark eyes shining brightly. “Now — this very minute?”

“Don’t be an idiot, Paul,” said Jack. “We’ve got to get a few things together. We ought to have guns, I think, for one thing.”

“I don’t like guns,” said Nora. “They might go off by themselves.”

“Guns don’t,” said Jack. “You girls don’t need to have guns. But where can we get these things — I’m sure I don’t know.”

“Pilescu, my pilot, can get everything we want,” said Prince Paul. “Don’t worry.”

“But how will he know what to get?” asked Mike. “I hardly know myself what we ought to take.”

“I will tell him he must find out,” said Paul. “Show me where your telephone is Mike, and I will tell him everything.”

Soon Paul was holding a most extraordinary talk with his puzzled pilot. In the end Pilescu said he must come round to the flat and talk to his small master. He could not believe that he was really to do what Paul commanded.

“I say — suppose your pilot refuses to do what you tell him?” said Jack. “I’m sure he will just laugh and tell us to go back to school and learn our tables or something!”
