Name That Television Programme

A Hitchhiker's Guide to the Galaxy

Hitchhikers is also a bit early - although you could say that about the time-slot this had.

Can i have a clue please

Absolutely, if you don't mind a cryptic one first. In the picture, you see one of Kate Winslet's exes.

Dark Season

Ooh - so close... as the saying goes...

It's three years before they met on the set for that.

She-Wolf of London?

Dogged detective work, but you're getting colder. We're talking Children's BBC in 1988, and ooh - did I mention time-travelling?

I've found a show called Moondial but it doesn't mention Stephen Tredre being in it.

I remember liking that and could still (badly) play you the theme music. Siri Neal was a nude artist's model the next time I saw her, in the Inspector Alleyn Mysteries.

This programme was entirely studio bound, at Pebble Mill and had a sequel in 1990 with the same presenter/narrator. The question isn't 'who?', but that helps!
