I used to love this show, mainly for the dramatic opening - a police vehicle (a Wolseley I think) speeding around a bend with bells ringing and the authoritative music playing over the credits. Sadly, those episodes seem to have been dumped and the later ones are poor by comparison. The opening is far less impressive and if I'm not mistaken by this time the show was made on tape in a rather cramped studio. Dingy and cheap-looking.
