From Russia with Love
SPECTRE's expert planner Kronsteen devises a plot to steal a Lektor cryptographic device from the Soviets and sell it back to them while exacting revenge on Bond for killing their agent Dr. No; ex-SMERSH operative Rosa Klebb is in charge of the mission. She recruits Donald "Red" Grant as an assassin and Tatiana Romanova, a cipher clerk at the Soviet consulate in Istanbul, as the unwitting bait.
Bond travels to Turkey and meets with Ali Kerim Bey, the MI6 officer in Turkey. Between them, they obtain the Lektor, and the three escape with the device on the Orient Express. However, they are followed by Grant, who kills Kerim Bey and a Soviet security officer. Grant pretends to be another British agent and meets Bond. Over dinner Grant drugs Romanova, then overcomes Bond. Bond tricks Grant into opening Bond's attaché case in the manner that detonates its tear gas booby trap, allowing Bond to attack and kill him. Bond and Romanova escape with the Lektor to Venice. Rosa Klebb, disguised as a hotel maid, attempts to steal the Lektor and kill Bond, but ends up being shot by Romanova.
