Vexed (2010)

No nudity in this series. Lots of discussions about having sex, and sex implied by overnight stays, but no active sex scenes. A couple of scenes of women in shirt and panties.

One or more murders in almost every episode, often with the victim visible for an extended time, frequently bloody but not severely gory.

Firearms are displayed occasionally, but rarely pointed at anyone and almost never fired (I don't recall an instance). In one episode, Jack asks a class of school kids who wants to hear about guns, and they cheer enthusiastically; he's shown talking with them but we hear little of what he says.

Various profanity throughout. In one episode, they use the F-Word.

Social drinking, some smoking of cigarettes.

Occasional scenes of people in imminent peril.
