SEASON PREMIERE: Thandie Newton returns as Grace, the undercover detective with a very complicated relationship with the people she’s investigating, in Season 2 of what is, or tries to be, a distaff version of Wiseguy. Season 2, which begins tonight, has Grace working with an FBI team investigating a local prostitution ring – but that plot doesn’t stay primary for very long, as Grace is pulled in new, even more dangerous directions.
