When journalists and detectives on TV get too emotionally invested in their work, it can be a good thing for the viewer. Assuming the script is smart, we get a chance to watch parallel dramas unfold. As we figure out who committed the crime, we also figure out how the investigator’s unresolved issues are driving him or her. The crime and the investigator become closely entwined, the dancer and the dance.
“Place of Execution,’’ the new “Masterpiece Contemporary,’’ does a middling job of blending a 40-year-old murder case with the problems of the documentary journalist who’s making a movie about it. Based on a Val McDermid novel, the two-part miniseries contains enough compelling genre twists to keep you genuinely eager to find out whodunit. But the portrait of workaholic journalist Catherine Heathcoat (Juliet Stevenson) is overly simplistic. “Prime Suspect’’ was the peak of this kind of psychological procedural, and “Place of Execution’’ does not approach those heights of characterization.
