Irina Bulganova was the former wife of Grigori Bulganov. She worked as a travel agent.
Irina is lured by the Office into visiting Italy for a non-existent travel conference. Eli Lavon interrogated her and learned that she was tricked into going to the United Kingdom to meet with her former husband, Grigori Bulganov. The people who tricked her used her as a hostage to abduct Grigori and take him back to Russia. Later, Eli went to her travel agency in Moscow and took her with him to England, where she stayed because her life was in danger if she remained in Russia.
