Landlady Kath may have had "an upbringing a nun would envy" - as she tells her prospective tenant Mr Sloane - but after that she developed very different habits. One of them is seducing her lodgers - especially when they are as markedly handsome as the blond teenager Sloane, whom she has met in the local library. So clearly amorous are her ambitions, however, that when the blowsy 41-year-old talks about wanting to mother the orphan, the name of Oedipus instantly springs to mind. Despite the misgivings of her old dad - who has dark suspicions that the boy is a murderer - he takes up residence and is soon involved in an affair with Kath. This does not go down well with her gangsterish younger brother Ed, a repressed homosexual who fancies the athletic youngster himself. We are heading for an eternal triangle rather different from most . . .

Entertaining Mr Sloane dates from 1964 - a period reflected well in Anna Johnson's set design - and was Orton's first success in a career that was shockingly cut short. He was hacked to death in 1967 by his lover Kenneth Halliwell. It is strange how aspects of Orton's own life are reflected in the play - especially in the sudden eruptions of violence that shatter what appears a humdrum domestic existence. In this sense, the piece shows the influence of Harold Pinter, which can also be seen in its precise and often quirky language. Where it differs from Pinter, however, is that the writing is much funnier.

The sudden switches from absurdity to menace were well handled in last week's enjoyable production by the student group False Teeth, under co-directors Sophie Duncan and Titas Halder. All four of the parts were skilfully presented. Alex Ball, as Sloane (above), with the good looks necessary to be convincing in the role, successfully suggested the cool cunning with which the character exploits them to his own advantage. Jessica Hammett gave us a Kath no less adept at getting her own way, whether by coquettish cajoling, fury or threatening floods of tears. Her part, it must be said, is most cruelly drawn, showing Orton's deep steak of misogyny. Tom Wilkinson's Ed was both strange and funny. His gloating enthusiasm during his first interview with the preening Sloane - in which were teasingly described the boy's sporting and other tantalising achievements - was a real hoot. Will Blair had the difficult task of aging 50 years to present the shuffling old dad, but managed to do it very well.
