A book series (I think) about a boy called either Tim or Sebastian. He had a black cat. Possibly the cat was called sebastian. He went on adventures with his cat, I think he travelled on a broomstick (but might not remember that right) and one of the stories he had a highwayman in it.
I was about 7? so, 1984 or so? they were not picture books, but I don't think they were longer books like Roald Dahl, smaller with some possibly black and white pictures on the odd page? The books were not bright and colourful, dark I think (I am thinking dark plots but that might be my mind interpreting the cover of the book?)
I asked at the library and they have no clue what I am talking about, neither do any of my friends of a similar age.
Do you lovely lot know what I am talking about?
(and, while I am at it, the librarian said she is trying to remember a child's programme where a monster looks through a window and into a story….
