Season 1 (Episode 1.10) Airdate September 13 2010

After an undercover cop working a narcotics-smuggling sting is shot dead, the killers next turn their sites on Boston homicide headquarters, leaving Jane, Maura and Frankie Jr. trapped in a fight for survival on their home turf. It's a situation that will force Maura to challenge herself like never before. On the home front, Jane's parents are excited that their oldest child, Tommy, is being released after serving time in prison.

Just finished watching the season's finale and all I can say is WOW !
I really hope Jane isn't going to be badly injured cause it will never be the same without her. I also hope Frank will make it although things looked pretty bad for him.
I had a hunch feeling this Bobby guy had an hidden agenda, it was already weird he got lightly injured while all the other cops got shot to death.
Oh man is winter over already?? I am so going to miss them

How brilliant was the finale!!? I actually thought that Frankie was going to die!! I like him so I hope he's ok in the next season... All the actors/actresses did a fab job!
