The story was gripping and thrilling. But the final twist was stupid. He could done it easily and directly. Instead he went through such a hard way. His Paranoia is understandable but it was not a strong motive for doing such a stupid and serious act. Even though except the last part everything was extremely well written, the climax twist reason was no upto the level. After all.. a good story needs a good climax, a believable and understandable one. Only read this book if nothing else is there. Bcoz after reading it, in the end I'm not happy or satisfied with it.
