Bond ... James Bond

[Alex]

The last words of the book are:

Spoiler:

"Yes, dammit, I said 'was.' The bitch is dead now."

The bitch is Vesper and he is telling MI6 that she was a double agent.

So far as I can tell the book ends after his discovery that she was a double agent for the Russians and she commits suicide while he is sleeping.

(This is from browsing the end of the book on Amazon and a text search shows no character in the book named Mr. White.)

Put in spoiler since iSm is apparently going to read the book.
