I don't know where to start this one!

I remember when I was younger, my mum had a book (i think it must have been from the library), and it definitely had something about a house on Ullet Road (I am sure it was number 9), and there had been reports of fairies in the garden.

That is really all I know,and can remember.
My mum reminded me of this last week, and she can't remember anything else either.
I just wonder if anyone else knows anything??
