Mercury Fur, 3-4 Picton Place, W1

Philip Ridley’s shockfest is brilliantly written and fully imagined

Imagine a future, a near future, in which gangs of teenage boys roam the deserted streets of the metropolis, selling hallucinatory butterflies and organising parties in squats for rich clients who have extreme tastes in sexual abuse. Imagine. This is the vividly conceived sci-fi world of Philip Ridley’s Mercury Fur, first staged in 2005 and now revived in an old London office block by the thrilling fringe company Theatre Delicatessen.
