I somewhat regret not getting into ABC's Count of Monte Cristo-inspired "Revenge," which is about a young woman who comes back to her hometown after years of being away, under a new identity, with the mission of destroying the rich family that drove her father to kill himself (I think that's the story).
When NBC debuted a similar show, "Deception," I decided to give it a try. In this show, the central mystery is the death by drug overdose of the older daughter of a rich family in New York. The FBI has been investigating the family related to its medical drug business but needs to get someone on the inside. How lucky for the lead FBI agent that his one-time paramour, now a San Francisco police detective, grew up in this family's house! You see, her mom worked for the family as a housekeeper/maid, and she was the same age as the now-dead older daughter, so not surprisingly, she became best friends with that girl.
(As an aside, the SF detective is African-American, as is the lead FBI agent, while the rich family is white. The show doesn't get in your face about the race relations, which I like, but I also don't think it's coincidental. There's a degree of subtlety here that works.)
Okay, so lead FBI agent talks SF detective into coming back to New York to go undercover and infiltrate the rich family. The dead daughter's funeral is the perfect entry point, and the detective's cover story is that she just got out of an abusive marriage and is looking for a new start. The dead daughter's dad shows warm feelings toward her and invites her to stay with the family for as long as she needs, and then hires her as an administrative assistant. However, some other family members are suspicious of her.
Haven't these people heard of Google? It's not like the SF detective can use a fake name; she has to be herself to be able to infiltrate the family. Yet, she was also using her real name with the SFPD. So if I were suspicious of her, after her 17 year absence, the first thing I would do is put her name in Google and see what pops up. I've got to think there would be some news stories/items about her as a police detective!!
