When Steve discards that, Harry falsifies a claim letter from the murderer and authenticates it on TV, causing a panic and high-profile resurrection of the task force, under Harry, who gets a call from the murderer, who already killed again. Now Harry shows Mark his theory the killer never stopped but worked in various oil-producing countries, painting clown-type faces according to local traditions, but Steve nails Sally Jenkins's killer, which compromises Harry's theory, yet captain Walter Newman won't even take him off the task force.
