From the very beginning, I wondered what the title had meant. After finishing the book, I have to say that now I know and I think it's a clever title.
As far as the story is concerned - rather average. We know what happened and who did it from the very start. I kept reading the book, hoping for more mystery but didn't really get it. It was a rather boring tale up until the end. Then, you kind of can see the ending coming. Disappointing.
