The Inside Man

DCI Jack Parker fights to hide his Early Onset Dementia while he continues to do the job he loves - investigating crimes & bringing villains to justice. Still haunted by the death of a colleague in a hit & run for which he blames himself, he pursues the case with a determination bordering on recklessness when he encourages her replacement, DS Emma Steel, to get close to a local gangster who knows more than he's letting on, thereby endangering Emma & causing dissent among his team. Jack is called in to investigate the disappearance of a young woman, Maria, & her son who appear to have vanished off the face of the earth. His boss tells him to focus on her ex-husband, but though the evidence points in his direction, Jack has his doubts. The woman has form with toxic men & the husband is just the latest in a long line.
