I've seen the movie twice now, never read the book. The Vesper backstory is vague in the film, but my take was like Wendy54's. My girlfriend had a different take, but this was mine:
1) Vesper was compromised by Mr. White's organization even before we meet her.M's explanation to Bond about Vesper's kidnapped Algerian b/f included "We should have caught that" as if it was something in the past that could have been caught in the either the Treasury application process or in the review of her file to accompany MI6 on this assignment. We just don't know how long she was compromised or whether she had accomplished other tasks as a mole for Mr. White's organization in the recent past. It is possible and likely that she had a Mr. White-given task at Montenegro to withhold Bond's second buy-in (making it more likely LeChiffre won). She's an accountant, not a spy, and eliminating Bond's second chance is a powerful advantage--perhaps the most she had to offer them, and the one that could set her b/f free. Her crying in the shower is true shock of a non-spy over the murderous world she finds herself in.
White's organization wanted to help LeChiffre win the money back by handicapping Bond. They would have killed LeChiffre after the card game anyway (win or lose) as an embarrasment to their own credibility with their clients.
2) Still unclear whether Mathis was a baddie. It could have been Vesper OR Mathis who relayed LeChiffe's "tell" to LeChiffre. M thinks the Vesper-as-baddie fact clears Mathis. Bond is correct when he says not necessarily. I expect we will see Mathis again in the next film as a guy who we can't quite tell is good or bad.
3) In the torture chamber, VEsper makes a deal with White to save Bond's life.White eliminates the embarrasment of LeChiffre. ("It's not about the money so much as knowing who to trust.") White had accepted the fact that the money was lost for good. White saw that there was no way he (or LeChiffre, or anyone else) could get the password out of Bond by torture. HOWEVER, Mr. White won't turn down $120MM euro when Vesper tells him she can deliver it to him in exchange for Bond's life!
M was consoling Bond when she said it, but she was right: BOnd was spared by White because Vesper made the deal to save him. I don't think White cared one way or another about Bond. He was there for LeChiffre. Vesper had to know that her Algerian b/f was probably dead by now since LeChiffre lost the card game, and White was now about to kill her too. "I can get the password from him," she probably said. By now she had personal feelings for Bond and, from her experience, Vesper saw that White's organization could kill anyone, anywhere, at any time.
4) Vesper can't bear the guilt of betraying Bond's love.She took off the necklace. Her mourning for her probably-dead Algerian boyfriend was surpassed by her love for Bond. That good-bye embrace at the hotel was awfully long if she was just going to see him again in 1/2 hour. Like M said, she probably knew she was going to die. That's why she left the note for Bond. She locked the elevator door and kissed Bond's hand lovingly goodbye. There was no escape: she knew she couldn't have Bond again after what she did. She was headed for life in prison anyway. And really, could any of us go on living w/o Bond?!!
I don't know. THat was my take. My g/f thought Vesper's Algerian b/f was kidnapped mid-film somewhere, revealed to her for the first time in the torture chamber, and that her motivations in getting the money were to save the Algerian b/f first and foremost. My g/f thinks Vesper was legit until the torture champber, and that White's group could not possibly have known that Vesper would be assigned to accompany Bond to the card game, and thus they had no motivation to kidnap her b/f until she became a central figure with access to the money. And she radically turned on the charm to Bond after they escape the torture--that's because she now had reason to. She has to do that to save her Algerian b/f.
But I can't accept that Vesper would or could bargain for Bond's life when they already had her motivated by her boyfreind's kidnapping, or that Mr. White would kidnap Vesper's b/f somewhere in the brief time after she gets assigned to the card game and before White sets out for LeChiffre and the torture chamber.
The debate will never be settled. (Unless we see what Haggis eliminated from the script!)
