All The Little Lights is a robust, complex play that encourages the audience to read between the lines and engage with the nuances of its three characters, estranged best friends Joanne and Lisa, trapped in a circle of love-in-hate, and 12 year-old Amy. Jane Upton’s script avoids a patronising signposting of content, and, in so doing, best suggests the insidious nature of its subject matter in a world where signs are missed, bruises hidden, and voices silenced.
