Iris Murdoch is engaging in a rather interesting game of intertextuality here, as Robert Irwin proclaims in his introduction. Whether this news makes your heart soar or sink truly depends on your tolerance for literary navel-gazing.
Apparently, the novel is a semi-farcical reworking of The Death of Ivan Ilyich. I could clearly see the farce part. You could simply read Tolstoy and your life would not be any poorer for having missed this one. And I haven't even begun to mention the occasional snippets from the Tractatus Logico-Philosophicus, nor the endless byplay that Murdoch attempts to attach to a stamp collection that perhaps symbolizes everything. Or maybe it symbolizes nothing at all.
However, it must be said that the book was well-written and Murdoch shows great inventiveness with the incidents. So, I give it two stars. But it will be a very long time before I decide to pick up another book by this author.
