The Silver-Handled Knife by Frances Thomas
Electra is eagerly looking forward to her father Agamemnon's triumphant return to Mycenae after the long war in Troy. But his wife Clytemnestra and her lover Aegisthus have other plans - Clytemnestra cannot forgive her husband for the sacrifice of her eldest daughter Iphigenia at the start of the war, and Aegisthus covets the kingship. Instead of celebrating his return, they murder him horribly; and suddenly Mycenae isn't a safe place for Electra or her brother Orestes. Orestes goes into exile, and Electra has to submit to a humiliating fate. When Orestes eventually returns, there is only one word on his mind - revenge!What part will Electra play in this?
