Stirling and Hollingworth are brilliant together, the ever-changing contours of their interdependency beautifully portrayed as the play winds to its visually stunning and emotionally compelling climax, reminding us that whilst old friends may seem like they’ll always be there, they need nurturing just as much as the rest of us. Bartlett’s customary acuity in exploding the way we relate to each other is as perfectly conceptualised as ever, he remains one of our most exciting young playwrights.
