“We’d better just keep a watch-out in case anyone else is looking for Paul,” said Jack. “You never know!“

So they kept a look-out, and walked beside the tall hedges to hide themselves till they got to Peep-Hole.

And what a surprise they had when they got to the field opposite Peep-Hole - for there on the grass was a big aeroplane! It was painted a bright blue, and had silvery edges that shone in the sun!

The children stopped in the greatest surprise. Nobody was in the aeroplane. Nobody was about at all. They didn’t know whether to go to Peep-Hole or not - did the aeroplane belong to the enemy? Or was it a friend’s? It was all very mysterious indeed.

Alone at Peep-Hole

The five children stared and stared at the aeroplane. Paul went rather pale.

“It looks like an aeroplane from my own country,” he said. “Do you think my enemies have flown over here to find me? If only I knew what had happened to my father - whether he got better or not! I am very unhappy.”

“Cheer up, old son,” said Jack. “We’ll soon find out everything. I expect Dimmy has told the police to find out what’s been going on in your country, and she’ll tell us as soon as we find her.”

“I want to see Dimmy,” said Nora. “I feel safe when I’m with her.”

“Well, let’s go quietly to Peep-Hole without being seen, and find her,” said Mike. So they crept along by the tall hedge, turned into the little lane where Peep-Hole stood, and ran into the small front garden.
