NCIS Season 7 Episode 21

Orphaned lieutenant Jeffrey W. Hutton, from USNavy's intelligence center NIOC, died in his crashed car from an at first sight mysterious cause, nearly having reached university hospital. His sister, ZNN TV star reporter Dana, disappeared shortly after becoming executor in charge of selling (for charity) the used books shop of Charlie Bascom, who died in another car crash. Having the hots for Dana, DiNozzo wants the case, and gets it because he has an NIOC contact. Palmer delights Mallard by doing spontaneous overwork and finding the key to Jeff's death, an old KGB poisoned mini-bullet. Dana was working on a story about certain private military contracts, Jeffrey already filed a report advising the joint chiefs of staff against the practice. A secret identity discovery links everything.
