While there's plenty of lying, stealing, and allusions to sleeping around among suspects, the bad guys always get their due in the end.
Each episode revolves around a death, and often the act of murder is shown as well as a few shots of the dead body (though it's all very tame compared to modern forensic crime dramas). There are lots of verbal threats ("I'll kill you") and some fist fights and scuffles here and there, which lead to bruises and bloody lips.
Characters occasionally talk around the subject of sex with loaded comments like "I don't know what you're doing or who you're doing it with." Extramarital affairs often pop up in investigations. Female characters sometimes dress in skimpy clothing. There's occasional kissing and some light fondling (rubbing thighs or backs, for instance).
"Damn" and "hell" are used infrequently.
