A beautifully written book, though definitely from another time. Three siblings and their mother leave their London home for the countryside because some men come to take their father away. What follows are a series of mini-adventures, mostly concerning the Railway and surrounding areas where the children express themselves through kindness and good deeds.
The reason I enjoyed this book so much was, not just for the wonderful old-fashioned language you find in books such as these (calling someone a brick always amuses me), but because it holds a very important message and that is you are not worth how much money you have. The children move from, not an unseemly amount of wealth, but definitely enough to afford a privileged lifestyle to barely being able to afford warming their house, resorting in the children "borrowing" coal in lieu of a game.
The whole point of life is to better yourself and it's quite difficult to do that when you're born in to money. But the children better themselves despite this, and in so many different ways it's hard to look back on this time and envy them for being able to live in it.
