Seeking revenge against MI6 agent James Bond for the death of their agent Dr. No in Jamaica, international criminal organisation SPECTRE begins training agents to kill him, before assigning the task to Irish assassin Donald Grant. To lure Bond into a trap, SPECTRE's chief planner, Czechoslovak chess grandmaster Kronsteen, devises a plan to have him attempt to procure a Lektor cryptography device from the Soviets from their consulate in Istanbul. SPECTRE operative Rosa Klebb, a former SMERSH (Soviet counter-intelligence) colonel, is assigned to oversee the mission and to ensure Grant can carry out Bond's assassination at the right moment. To set the trap, Klebb recruits a cipher clerk at the consulate, Tatiana Romanova, to unwittingly assist in the plan, tricking her into believing she is still working for SMERSH.
