Rebecca Lenkiewicz is happy to take on a large well-thumbed subject and find it new and fresh. She can write a good character and place it comfortably in a historical context. The play is full of them, each one demanding attention, from a strong cast happily devoid of weak links. It is a well-made play in the best sense, having its own internal rhythm and emotional sweep, which leads to its disturbing climax.

It is a wise decision to rid the Birmingham Rep’s Door Theatre of its curtain for this production otherwise its opening scenes would be muffled by the pantomime oohs and aahs of the audience upon seeing the magnificent set – an airplane fuselage and luggage incongruous in a jungle setting . . . The complex yet practical set includes fire pits, drop-down ramps, miniature ladders, ropes and hidden compartments, all of which are gradually unveiled, so that what is man-made and what is of nature become inseparable, if not indistinguishable.

Humour finds its way into the script: for example when the landline telephone rings she knows its her mother – for as we all know, only parents and nuisance calls don’t use out mobile numbers. The directing and performance are literally ‘off the wall’. Sarah Beaton’s clinical, shiny white set provides shelves and handles on the back wall onto which Miss Jackson leaps with all the sure footedness of a mountain goat. Standing or crouching she talks directly to the audience via the conceit of making a video.
