Frequent violent killings shown in great detail. Eg, stabbings, shootings, hangings. The violence gets more mild in late series's.
In nearly every episode, Vera & her team are investigating one or more murders, and the victims' bodies are shown at both the scene of the crime and in the police morgue. Occasionally, the actual attack is shown, though often it is only implied. There is usually some amount of blood, bruising, and wounds shown at the crime scene, but these are not especially gory or explicit. Victims are often shown on the post mortem table with stitches on their torso, bruising, stab wounds, etc. - again, not gory at all. Other mild violence is occasionally shown, such as fighting, shoving, slapping, etc.
