I’m trying to remember the title or author of a book that Fast Young Git really enjoyed hearing me read, yonks ago. The story went ‘Once upon a time there were three fierce robbers. They went about under tall black hats… There was a girl called Tiffany, I think

Three Fierce Robbers goes no-where on Amazon. And another child might like it.

Thanks.

That’s what you need, I think.
