Probably shouldn't be a surprise that the letters are so good since Graham wrote excellent letter poems! The letters are in a sense poem drafts - he says in one that he writes the letters as much for himself as for the recipients. Wonderful early and a few late letters to Edwin Morgan discussing his writing, wonderful exuberant letters to Elizabeth Smart, Michael Schmidt gets a telling-off letter for a review he wrote about him, letters about writing, begging for money, his poverty-struggles, all packed with personality and most of all humour. Letters I'll go back to.
I'm excited to have just finished a seven-poem sequence on Mary Queen of Scots! I was keen to write about her after I came across and read some of her letters on-line. What surprised me was how human she seemed as opposed to the distant stock character queen from history. I read the well-written and in-depth biography of her by Antonia Fraser. There are many surviving letters written by Mary and many recorded first-hand accounts that it is possible to build up a reasonably accurate picture of her as a person. Plus there are so many mythological aspects to her story which is a gift to write about.
