After last week's episode, which worked hard for its laughter, tonight's is a far more relaxed and subtle affair. Bernard (Dylan Moran) and Manny (Bill Bailey) decide to write a children's book. Bernard's first attempt at entertaining four to six-year-olds consists of a 1,300-page saga about the relationship between an academic who survived the Stalinist purges and a daughter whose long and bitter marriage is collapsing. "You should never talk down to children," he says. The episode plays to one of the great strengths of the series - the antagonistic co-dependence that binds the main characters together. It is a wonderful return to form.

Irish comedian Dylan Moran has already proved he can act in sitcoms. But now he's teamed up with Graham 'Father Ted' Linehan to write one. They both talked to Maxton Walker about the surreal result, Black Books.
