By having a narrator who doesn’t fully understand the implications of his narrative, the writer Robertson Davies, leaves more interpretation to the reader’s imagination.

Dunstan is a pretty reliable narrator so I'm not exactly sure what you are asking here.

I soglasen with the answer above.
In fact, Robertson Davies is a great writer and his occupation a little thought-provoking. To write as a novelist, playwright. Izlogat as a critic and to be able to be a journalist. Not everyone's strength. I would advise a little more specific with your question or rephrase it.
Sorry for the reply.
