JUST LIKE the way the Presidency of the EU rotates between different countries, so a script involving posh kids in a haunted house was passed around the ITV regions during the 1970s so everyone could have a crack at it. And here’s Bristol’s turn! Adolescent toffs, haunted stately pile, blah blah – but wait! There’s time travel to boot! Thanks to weird antique carving thing, the posh kids suddenly find themselves in the 18th century where they have to help a black slave (BRINSLEY “ASWAD and DOUBLE DECKERS” FORDE, no less!) return to his home country. Which they do. And that’s it.
