Found this clearing out my former family home. This was a book I bought on a programme by which schoolchildren could buy cheap books, back in 1977 or thereabouts.

The story is competently written, but there's not much there. Two children whose parents are away meet a wizard and hide him in their attic, whereupon they get into plenty of trouble trying to have adventures with him. The adventures are all variations on the one theme of "Be careful what you wish for - you might get it."

The character I liked best was George...

For release.
