Agent of Influence: The Secret Life of Pamela More

Its heroine is The Times fashion correspondant, a snobbish, bitchy, and frighteningly apolitical lady of a certain age. But even so, she's a thoroughly endearing creation: Rebecca Dunn's wittily glib performance makes her a kind of social chameleon, who mirrors the bleak political colours of her time without even realising it. 

A surprise visit from a secret service agent shakes her out of her complacency, and into a mission to spy on Wallis Simpson – under the pretence of writing a newspaper feature on her wardrobe of exceedingly pricy frocks. Retro fashion buffs will delight in the magic of the names that trip from her lips: Schiaparelli, Mainbocher, House of Hartnell. Alberta Jones's design is a joy, too – where most Fringe shows keep sets to a barest minimum, she's filled a dank cellar with a stylish abstract setting that immerses us in Pamela's stylish world.

It's a sharp insight into a time where the British aristocracy were mad keen on fascism – mainly, but not exclusively, because they were terrified of communism. But there's also a sense of a post-WWI generation who were determined to ignore anything depressing or dreary. Pamela's love of fashion is an escape, as well as a vocation.

However stylish it might be, this isn't theatre at its most extravagantly original. But it's very, very nicely done – a little jewel of a period drama, in a rather unlikely setting.
