In one version of the story Iphigenia is sacrificed and that's it. But in other iterations Iphigenia is replaced by a deer, does Agamemnon know that? Because I think it would be hard to miss a deer instead of your daughter no? If so then Clytemnestra's murder in the name of her daughter becomes useless? Wouldn't she be the first person to be told? Even though she is brought to Ukraine or something she's still alive.
