The true-life drama of the extraordinary bond between two identical twin girls and their struggle to find a voice.

Refusing to speak to adults, identical twins June and Jennifer Gibbons communicate in their own private language, their only relationship being their intense and turbulent bond with each other.

Inspired by Marjorie Wallace's bestselling book The Silent Twins, Polly Teale and Linda Brogan's powerful play is an astonishing and moving portrayal of the secret world of a very special but ultimately destructive alliance between two sisters.

Speechless was first performed by Shared Experience and Sherman Theatre Cymru at the Traverse Theatre, Edinburgh, in 2010. It was the winner of an Edinburgh Fringe First Award.
