NCIS Season 4 Episode 15

Petty officer Evan Davidson is found in an abandoned Georgetown home, dead for days after a heavy night drinking. What seemed alcohol OD is in fact oleander poisoning. In collaboration with two civilian Metro Police detectives, a series of clues leads to Scott Pell's exclusive and discrete night club, and a vagrant who stole Davidson's wallet. Deliberate clues only an expert could plant and strangely related other murders. Meanwhile Tony's date Jeanne Benoit must deal with her other relationship, which she's denying.
