Word gets to Bond that a soviet agent wishes to defect as she as fallen in love with the British agent. She says that she will steal a Lektor (a decoding device) in advance to be allowed to be escorted by Bond to England. MI6 grabs the opportunity quickly, even though they realise it could be a trap. The "defector" Tatiana Romanova dosen't know that her superior, Rosa Klebb is actually working for SPECTRE who also wants the Lektor to sell back to the Soviets to raise funds. All this would leave MI6 humiliated and hopefully have Bond killed while he gets the Lektor. To avenge the elimination of Dr No 007 meets tatiana in Istanbul, with the help of Kerim Bey, an intelligence gatherer there. They steal the Lektor then board the Orient Express to head home. Donald Grant a well trained SPECTRE assassin has all these movements tracked and discretely follows them aboard the train. Grant murders Kerim but Bond catches him and strangles Grant in a tough fight which ends with Grant dead. Bond and Tatiana escape to Venice but are again tracked down by SPECTRE. The couple destroy the crime organisation's fleet of motorboats and make it to Venice. They then come across the last obstacle Rosa Klebb. She makes one last attempt to get hold of the Lektor but Tatiana shoots her in the nick of time.
