I seem to remember reading somewhere (DWM?) that there was a planned vampire story in the Hinchcliffe era, but there was something similar from another part of the BBC so they weren’t allowed to do it
It was actually the Williams era (though maybe the story was commissioned by Holmes under Hinchcliffe as it was the very first Williams one) as Dicks's original vampire story got nixed because of sensitivities around a supposedly high profile adaptation of "Dracula", so Terrence wrote "Horror Fang of Rock" at fairly short notice to replace it.
