7x12 - A Candle for the Murderer

November 21, 1980

Dernberg is dead in his photo laboratory. Near the body, Inspector Derrick finds a piece of paper with the word "school" on it. An important clue as it turns out. A pastor suddenly appears with the desire to say a prayer for the murdered man. Derrick meets him again the next day—of all places—at his school, near the crime scene.
