As Thick as Two Planks of Wood

It is the seventy-fifth year of Middlestitch School in London. Celebrations are planned, there is an excitement in the air. However, one pupil, James Figg has a problem he cannot get out of his mind-his holiday in the hills of Wales. It was there he first found a friend called Ash; and it was then things started to go rather odd. Even his form teacher Mr. Phanning became involved, as did Miss Caramila, the music teacher. Do not forget the excitement of Ms. Manley the headmistress-also not to forget-the Almost Welsh School Choir.
