The deal is interrupted by Kirill, a Russian Federal Security Service agent who works for oligarch Yuri Gretkov.

He kills the agent and source, steals the files and money, and plants fingerprints framing Bourne for the attack.

Some years ago, Russian politician Vladimir Neski was about to identify the thief when he was killed by his wife in a suspected murder-suicide in Berlin.

He subdues a Diplomatic Security agent and a Carabinieri guard and copies the SIM card from his cell phone.

Danny Zorn, Conklin's former assistant, finds inconsistencies in the report of Bourne's involvement with the death of the agent and explains his theory to Abbott.

Bourne breaks into Abbott's hotel room and records a conversation between him and Gretkov that incriminates them in the theft of the $20 million.

She thanks him for the tape, reveals his original name, David Webb, and his date and place of birth, and asks him to meet her.
