Obsession

DiNozzo finds himself captivated by a woman he's never met while investigating the death of her brother. The woman is the world renowned reporter Dana Hutton, who has disappeared shortly after her brother's death. At first, the team believes that the murder may be connected with the siblings' work on investigating Private Military Contractors, but begin to suspect that the KGB may be involved when they discovered Dana's brother was killed by a Ricin pellet. It soon turns out that the man who brought Dana Hutton and her brother up was a KGB asset codenamed "Yuri" who owned a bank account on which the KGB stashed $10 million for use in their US intelligence operations. DiNozzo manages to contact Dana and gain her trust, and she helps the team recover Yuri's KGB documents and money, but reveals she had been injected with ricin as well. With the documents, the team find the operative who killed the Huttons as being one of the KGB agents who didn't return to Russia after the Cold War ended and who wanted to get her hands on the money that Yuri had stashed away.
