After an operation in Istanbul ends in disaster, Bond is missing and presumed to be dead. In the aftermath, questions are raised over M's ability to run the Secret Service, and she becomes the subject of a government review over her handling of the situation. The Service itself is attacked, prompting Bond's return to London. His presence assists MI6's investigation in uncovering a lead, and Bond is sent to Shanghai and Macau in pursuit of a mercenary named Patrice. There, he establishes a connection to Raoul Silva, a former MI6 agent who was captured and tortured by Chinese agents. Blaming M for his imprisonment, he sets in motion a plan to ruin her reputation before murdering her. Bond saves M and attempts to lure Silva into a trap, and while he is successful in repelling Silva's assault, M is mortally wounded. Bond returns to active duty under the command of the new M, Gareth Mallory.
