Dimensions

     I will just say then: I have seen the children.
     I have seen and talked to them.
     There. What are you thinking at the moment? ... But I want to tell you ... they exist. I say they exist, not they are alive, because alive means in our particular Dimension, and I am not saying that is where they are. In fact I think they are not. But they do exist and it must be there is another Dimension or maybe innumerable Dimensions, but what I know is that I have got across to whatever one they are in. 

From Alice Munro's Too Much Happiness

He is not a criminal. Lloyd is only criminally insane. The only mystery I had yet to figure out in the back of my mind was whether he killed the children. 

He did. He used pillows to stifle them. And Sasha--he was a tricky one because was smart--he tried to escape. So for Lloyd to say that he saw the children in another "Dimension"--does that justify anything for Doree?

Doree intended to see Lloyd, to talk to him about the children and their "Dimensions" in her undisguised, truthful self. In the very end, however, she decides not to go to London. She decides to bring a young man's life back instead. Perhaps she finally finds the Dimension she belongs to.
