The most interesting thing about this book is the way different narratives or different realities are placed one on top of another, and sometimes mingled. Blackeyes is the name of a character in a novel inside the novel called 'Blackeyes'. The inside novel is called something sexier. And the character Blackeyes is an astonishingly beautiful young woman found naked and dead in a cold pond. Whether she killed herself or somebody else did it is a matter of investigation. The story of Blackeyes, the character, was told by an astonishingly beautiful young woman to her elderly writer uncle, but the young woman disagrees with the way the old man wrote the story.
If you think this female-male contest for ownership of narrative sounds to have come from some sort of literary theory, then I think you are right. But this is not an academic, dry read. It has many pop flourishes such as the already mentioned suspected murder, as well as sex, romance and maybe some dark secrets, too. In fact, at one point, the 'real' author complains of 'embarrassment' at the popular romance turn the tale takes.
The weak point maybe that the characters are too much pop stock. The preternaturally beautiful young woman with sorrow in her heart, the vain, bombastic, has-been, never-was literary old gent with a vulnerable centre, and a tough, weary, seen-it-all, dedicated detective.
There are some dated bits of satire on 'youth speak' that seems to come from a decade or two before the story, and the emotionless sex with multiple partners seems very pre-Aids though the novel was published in 1987.
The thing that keeps it interesting and worth reading is that complex structure that is easier to understand than to describe, freshening up all the potentially stale elements in a witty and entertaining way.
