It was the last leg of the journey. The roads became long and straight and carved their way between some very high hills.

Soon they found themselves approaching signs that said,

Then

I mean, I don’t think I can make it any plainer – they were getting closer to Scotland.

“We’re nearly there!” said Janet.

“Well, not quite,” said Amy. “My dad’s place isn’t right on the border.”

“Are we going to where he lives?” said Rahul.

“No,” said Amy. “We’re going to where he works.”

“Why?”

“You’ll see when we get there,” said Amy.

“So how far from the border is that?” said Janet.

“Not far. Well, actually I’m not sure. But I know a man who does. Or at least the voice of a man. Or a woman.”

She pressed the sat nav button.

“You take the High Road …” it sang.

“Oh!” said Amy.

“And I’ll take the Low Road …”

“Why is it Scottish now?”

“I think it might have a program where it does whatever accent suits where it is,” said Rahul.

“And I’ll be in Scotland afore ye,” it continued.

“Well, you won’t, Mrs Sat Nav,” said Jack. “Unless something very strange happens, we will both be in Scotland at the same time.”

“This isn’t telling us how much further we have to go,” said Janet.

“Yes. I’ve just realised that’s because it’s the radio,” said Amy. She pressed another button.

“Stay on this road for twelve miles,” said the sat nav in a completely normal sat nav voice. “Then you will have reached your final destination.”

“HOORAY!” shouted all the children at once.

And this was when the Taylor TurboChaser made its most painful-sounding noise yet – not a groan but more of a long, extended whimper – and then ground to a complete halt.

“Oh dear,” said Amy.
