Wednesday evenings will be dull without Eric. As this neat little four-parter draws to a close, the Faustian tale reaches its fiery depths as the frankly hopeless team of time travellers find themselves in Hell.

Fortunately for petulant human teenage spell hacker Eric (Will Howard) and jinxed junior wizard Rincewind (the understated comic genius that is Mark Heap), the King of Hell's demons are easily confused and distracted. And then there's the infernal bureaucracy to tackle. But have our anti-heroes learnt their lessons and will Eric ever get to return to his bedroom?

The devil only knows and he's not telling.
