“No. I don’t,” said Jo. “Dad’s taken her somewhere else. I expect he put her on Blackie, because Blackie’s gone, too.”

“What about Timmy?” asked Dick.

Jo looked away. “I reckon they’ve done Timmy in,” she said. Nobody said anything. The thought that Timmy might have come to harm was too dreadful to speak about.

“How did you find us here?” asked Julian at last.

“That was easy,” said Jo. “I can follow anybody’s trail. I’d have come quicker, but it got dark. My, you did wander round, didn’t you?”

“Yes. We did,” said Dick. “Do you mean to say you followed all our wanderings in and out and round about?”

“Oh, yes,” said Jo. “Properly tired me out, you did, with all your messing round and round. Why did you leave the wheel-ruts?”

Julian told her. “You’re daft,” said Jo. “If you’re going somewhere off the path, just mark the trees with a nick as you go along — one here and one there — and then you can always find your way back.”

“We didn’t even know we were lost till we were,” said Anne. She took Jo’s hand and squeezed it. She was so very, very glad to see her. Now they would be able to get out of this horrible wood.

Jo was surprised and touched, but she withdrew her hand at once. She didn’t like being fondled, though she would not have minded Dick taking her hand. Dick was her hero, someone above all others. He had been kind to her, and she was glad she had found him.

“We found something written on the caravan wall,” said Julian. “We think we know where George has been taken. It’s a place called Red Tower. Do you know it?”

“There’s no place called Red Tower,” said Jo at once. “It’s…”

“Don’t be silly, Jo. You can’t possibly know if there’s no place called Red Tower,” said Dick, impatiently. “There may be hundreds of places with that name. That’s the place we’ve got to find, anyway. The police will know it.”

Jo gave a frightened movement. “You promised you wouldn’t tell the police.”

“Yes — we promised that — but only if you took us to George,” said Dick. “And you didn’t. And anyway if you had taken us to the caravan George wouldn’t have been there. So we’ll jolly well have to call in the police now and find out where Red Tower is.”

“Was it Red Tower George had written down?” asked Jo. “Well, then — I can take you to George!”

“How can you, when you say there’s no place called Red Tower?” began Julian, exasperated. “I don’t believe a word you say, Jo. You’re a fraud — and I half-believe you’re still working for our enemies too!”

“I’m not,” said Jo. “I’m NOT! You’re mean. I tell you Red Tower isn’t a place. Red Tower is a man.”

There was a most surprised silence after this astonishing remark. A man! Nobody had thought of that.
