While Obanno is enraged over the loss of money, Mr. White is more concerned that his employer's reputation has been damaged because a contractor betrayed their trust. Consequently, Le Chiffre's pleas for mercy do not satisfy Mr. White, who personally executes him by shooting him in the forehead with a silenced Walther P99. This also spares Bond from further torture at the hands of Le Chiffre; unwilling double agent Vesper Lynd made a deal with Mr. White's organization to spare Bond in return for the $120 million.
In Venice, while the organisation's thugs kidnap Vesper and battle Bond, an unnoticed Mr. White retrieves the money. With Vesper's suicide, it appears that the money and MI6's attempted trace to Mr. White's organisation is gone, but Vesper leaves Bond the number for Mr. White on her cell phone.
In the final scene of Casino Royale, Bond traces Mr. White to his villa along Lake Como and shoots him below the knee with a suppressed HK UMP9. It has been confirmed that Mr. White will return in Casino Royale's sequel, Quantum of Solace.
