The Outsider by Stephen King, book to mini series review

In Flint City, Oklahoma, police detective Ralph Anderson arrests popular teacher and Little League coach Terry Maitland in front of a crowd of baseball spectators, charging him with raping, mutilating and killing an eleven-year-old boy. Maitland hires his friend and lawyer, Howie Gold, to assist him but Anderson has eyewitnesses and clear forensic evidence pointing to his guilt. In the meantime, eager reporters harass Maitland's wife, Marcy and his two daughters, Sarah and Grace. District Attorney Bill Samuels tells Anderson to break Maitland's alibi in order to make this an open-and-shut case. Anderson discovers, however, that multiple eyewitnesses confirm Maitland was out of town when the murder occurred, at a writer's conference in a neighboring town. Conference site security footage also provides confirmation of Maitland's alibi. Anderson finds a book at the conference center gift shop that Maitland (or his doppelgänger) touched and the fingerprints on the book are confirmed to be Maitland's. Samuels encourages Anderson to destroy this new evidence but he does not. Despite evidence that Maitland was in two places at once, Anderson still believes Maitland killed the boy. Maitland is shot to death outside of the courthouse by the older brother of the victim, who is subsequently shot and killed by Anderson. Anderson is placed on administrative leave and the district attorney decides not to seek reelection. With the help of private investigator Holly Gibney, Anderson follows a trail of clues that takes the duo to Marysville, Texas. Jack Hoskins, Anderson's rival in local law enforcement, is coerced by the Outsider (the real killer) into killing Anderson. The Outsider promises Hoskins that if he kills Anderson he will be cured of his cancer. With the help of a number of characters, Anderson and Gibney discover that they have an actual monster on their hands. They set out to destroy him in a large cave in Marysville, where two children died years earlier. Holly hits the Outsider with the happy slapper (a sock filled with ball bearings, similar to what she used to stop Brady Hartsfield in Mr. Mercedes). He appears destroyed. The district attorney holds a press conference clearing Maitland, alleging defective DNA samples and confirming the video proof supporting Maitland's alibi.
