Elementary

Sherlock Holmes is an ecsentric eccentric genius who had been released from the rehab. He moved from London to NY, where he has to leave live with his "babysitter," ex-surgeon lovely Watson (played by the lovely Lucy Liu). {There are a few ways to say it -- that's how I would do it.} She is employed by Holmes' father against Sherlock's' will. Watson's job is to take care of Holmes Sherlock {for consistency} and protect him from getting back to his drug addiction. {A more natural way to say it: "...and keep him from relapsing."} Holmes Sherlock is not pleased with the whole situation, and gives Watson a warning: tells Watson that he is the only person in control of his life and that no one will tell him what to do. {"warning" isn't quite right here} Watson doesn't really have much of a choice. She's been already been hired by his father and she has to fallow follow Sherlock everywhere. After a while, they become good partners and solve mysteries together.
