This is the second Russell book I've read. The second of what I hope will be many, many more. I find it difficult to find the right words to describe how much this book moved and entertained me. At the base of this book is a murder mystery. But in many respects I think of it more as a vehicle to move the human story that is the true focus of the book. A detective is faced with a potential witness or even suspect who suffers from dissociative identity disorder (multiple personalities). Though he knows little about this disorder, with the help of Helen's (the witness's) psychiatrist, he begins to learn the complexity of the disturbed and disturbing life that Helen lives. What is so moving and wonderful about this story is that the reader learns that all three (detective, psychiatrist, and witness) suffer from various wounds that they struggle with. Russell's ability to put the reader inside these personal and profound struggles is astonishing. I've seen a few movies about DID, Sybil and The Three Faces of Eve come to mind. But Russell's protrayal is, well, astonishing!!! I was so invested in these three characters and their struggles that I almost wanted to skim my way to the end, and yet wanted to read every word carefully because they are so skillfully woven on the page. The investigation is interesting, but more so because of how it pulls the characters to the story's conclusion. I HIGHLY, HIGHLY, HIGHLY recommend this novel. And I'll be seeking my next Russell book!
