Helen Cooper 
Three Women and a Piano Tuner (NHB Modern Plays) [EPUB ebook] 

An offbeat, lyrical drama about how our hopes and dreams can be thwarted by the choices we make — and by the ones we don't make.
Ella's got a project. After ten years she has completed her piano concerto, and now she needs the help of Liz and Beth to get it performed. But first they've got some history to negotiate, and some old scores to settle.
'a complex, slippery study of psychological crisis… poignant and roaringly funny' — The Times
'an astonishing piece — witty, emotionally raw and deeply affecting — that leaves you gasping at the imaginative ingenuity of the dramatist's central conceit… exceptionally touching and ingenious' — Telegraph
'a strong, beautiful, haunting play' — Sunday Times
