Everyone familiar with The League of Gentlemen will know what to expect from Steve Pemberton and Reece Shearsmith's latest offering. It is a characteristic mix of grotesque characters and sick imaginings, amid a bracing absence of anything remotely resembling good taste. That's not a criticism, mind. Although billed as a comedy-thriller, the comedy is as bitter as chocolate made from 100 per cent cocoa solids. But in the absence of laughter, there is a twisted narrative like a coherent nightmare, weaving together the story of an embittered clown, a disturbed midwife, a serial killer, a lovestruck dwarf and a blind collector of soft toys. As with The League of Gentlemen, Pemberton and Shearsmith take on the roles of multiple gargoyles alongside a cast that includes Dawn French and Janet McTeer. Once again they have created a fully imagined world unlike anything else around.

A sinister clown with a fake hand, a blind toy-collecting recluse, a midwife besotted with a baby doll - no surprise to learn the creators of this new comedy thriller are The League of Gentlemen's Reece Shearsmith and Steve Pemberton.

"The BBC wanted a family show, but things didn't pan out" admits Reece, 39. "In fact, its more horrible than The League! TV executives kept telling us, 'Dark comedy is out - we want big and funny' but thankfully, BBC bosses liked it."

As with the inhabitants of their previous creation, Royston Vasey, Psychoville is crammed with strange, sinister characters. They have nothing in common, except five of them receive an anonymous black-edged card that reads 'I know what you did...'. However, unlike The League, Reece and Steve play only a few roles, and instead have a starry line-up of regulars and guests, including Dawn French, Janet McTeer and Eileen Atkins.

Reece, who lives in North London with his wife Jane, says his kids - Holly, six and Danny, four - will have to wait a long time before they're allowed to watch his gruesome shows. "They'll have to be at least 35" he laughs, "They call it 'Daddy's silly work'. But I'm draconian about what they see, which is hypocritical because I saw lots of gore as a kid - but then look how I turned out!"
