Season overview

Role: Meticulous television and film archivist.
Task: Create a JSON object for "Castle" Season 5.
Keys: overview (160-220 words), primer (array of exactly 4 concise bullet points).
Constraints: Use ONLY provided synopsis and sources. No invented facts. No markdown/asterisks/headings. No guessing. Output valid JSON only.
Source Analysis:
[1] TMDB: Season 5 has 24 episodes. Overview snippet: "After a serial killer imitates the plots of his novels, successful mystery novelist Ric..." (incomplete).
[2] Wikipedia: ABC series, 8 seasons, March 9, 2009, to May 16, 2016. Produced by Beacon Pictures and ABC Studios.
[3] IMDb: Created by Andrew W. Marlowe. Stars Nathan Fillion, Stana Katic, Susan Sullivan, Jon Huertas. Richard Castle teams up with NYPD Detective Kate Beckett to solve complex murder cases.
[4] TMDB Cast & Crew: Richard "Rick" Castle receives permission from the Mayor of New York City to tag along with an NYPD homicide investigation team for research purposes after a serial killer imitates his novels.
[5] IMDb: First case involved a nanny found dead in a spin dryer.
Overview: The provided text for Season 5 is extremely sparse. It says "Castle Season 5 continues the overarching saga across 24 episodes." The snippet about the serial killer imitating novels is part of the general overview, but doesn't explicitly state it is only for Season 5 (though it's the only context provided). However, the prompt asks for a 160-220 word summary of this season's narrative arc.
Problem: The provided text does not contain enough information to write a 160-220 word summary of Season 5's narrative arc. It only says it has 24 episodes and continues the saga.
Constraint Check: "If a detail is not in the provided material, you omit it rather than guess." "You never invent or guess... plot points."
Conflict: I cannot meet the word count requirement (160-220 words) without inventing information, which is strictly forbidden.
Strategy: I must write as much as I can from the provided text without violating the "no invention" rule. If the text is insufficient to reach 160 words, I am in a bind. Let's re-read the sources carefully.
