I loved the film based on this novel. I see a lot of folks saying that the film is better, but the two are so different that I hesitate to compare them. The premise is the same, but from there (even on the major plot points), they diverge substantially. In rereading the film synopsis on the heels of finishing the book, I'd say the book's plot is much stronger, but the film was more enjoyable for me because the pacing was better. The beginning of the book is a bit on the slow side. The end left me just as breathless, however. 
 Another issue I had with the early part of the book was the protagonist's apathy. It's understandable, but I found it so overwhelming that I had trouble connecting with him. I know it gives his eventual changes in attitude more impact, but it might be a fine line for some readers. 
 Still, brilliantly done. I should give some of her mysteries a try.
