Sophocles 
Electra 

Locked into a bloody cycle of murder and reprisal, Electra, haunted by her father's assassination, is consumed by grief and a thirst for vengeance. When her brother Orestes at last returns, she urges him to a savage and terrifying conclusion. Frank Mc Guinness's charged adaptation of Sophocles' powerful tragedy was first performed at the Chichester Festival Theatre in 1997 and was revived at the Old Vic, London, in 2014.
