Smoking and Drinking: No smoking, some casual drinking.

Violence: Some live gunshots.

For which audiences: PG-13 to be on the safe side, although most 10 year olds and their parents would have no problem with this material.  It’s a classic British thriller similar to any Masterpiece mystery TV program.
