It may be dated, yet how contemporary, cool and compelling this Noel Coward tragi-comedy of his gay youth remains today. Michael Grandage's production, marking his debut as Sam Mendes's successor at the Donmar, is far from first-rate. But the scenes of fraught decadence and pained, eloquent truth-telling on Christopher Oram's chic, black and white set, with Cubist, chrome and leather accessories, are thoroughly bracing. It's a play in which the enviably mature Coward took a rare turn to the serious and psychological, with outrage sparked at its 1924 premiere. The wit comes with a real sting. The young playwright mixed a stiff, sour cocktail of sex and drugs for staid theatre-goers and asked them to savour scenes in which Florence Lancaster, a middle-aged, high society wife, is gladly caught in the grip of adulterous passion for Tom Veryan, a Guards officer less than half her well-camouflaged age.
