See how we neatly avoided giving a story title then? It's hard enough deciding what to call the first story (your host Toby Hadoke is an An Unearthly Child man himself, but he's no dictator) but what about if you strip it of its iconic opening instalment? Because that is what monster maker Jim Sangster, this edition's special guest, has done. He's chosen the first story, but the caveman episodes only - in order that the oft overlooked squabble about fire might ignite fresh passions in us all. But will he and your host be fanning the same flames or will they be left with a chill in the air?
