It hardly seems possible, but Psychoville gets more grotesque by the week. Tonight, that principally means some alarming developments involving Little Freddy Fruitcake, who suddenly comes over, as we always knew he would, all Chucky. Meanwhile, David and Maureen arrange to meet their next victim in a waxwork museum, clowns Jolly and Jelly move towards an uneasy alliance, and we learn more about the secret that binds the main characters together.

Alfred Hitchcock was a film-maker who could be relied upon to find the grotesque humour in any given situation. It's therefore appropriate that tonight's instalment of Psychoville, possibly TV's first gothic sitcom-cum-thriller, should pay homage to Alf. More surprisingly, Reece Shearsmith and Steve Pemberton choose to riff off Rope in an episode shot in two long takes, with the murderous David and Maureen at the centre of the mayhem. Prepare for a killing, a trunk, an unexpected caller, a sudden panic and a fixation with pyramid teabags.

Reece Shearsmith and Steve Pemberton's eerie comedy just keeps getting better. That's largely because the plot, in the grotesque manner of a cockroach scuttling for safety across a kitchen floor after the light has been turned on, is accelerating. Tonight, that means a murder most horrid, backstory to explain the tension between Mr Jelly and Mr Jolly, a bidding war between Lomax and the Crabtree sisters, and the appearance of a video in the post. Worth watching just for the soft play pursuit scene.

Like The League Of Gentlemen turned up past 11 - which is a good thing, by the way - Reece Shearsmith and Steve Pemberton's grotesque blackmail comedy continues. Tonight, there's the revelation of a terrible secret from the past, which leads on to the discovery that toys can be "commodities" and that dwarf porn is issued under the Midget Gems moniker. God alone knows how it's all going to turn out, but the journey's the thing.
