How does Iris Murdoch use imagery in The Book and the Brotherhood?

Imagery:

"Death dries the tears of the dead."

"Tamar could not help wishing that some magic could mend it all. Why couldn't money solve everything? Money here seemed to glow with rationality, sense, justice, and almost virtue. But it was impossible. Tamar could not either leave her mother or save her. It was like something awful in a fairy tale."
