Ep 3. One Good Turn (1)

Jackson Brodie, the ex-cop turned private investigator, takes on a new case in "One Good Turn (1)," the third episode of season one of "Case Histories." The episode opens with Jackson attending a literary festival in Edinburgh, where he is approached by a man named Harry who asks him to investigate a case of identity theft.

Harry claims that someone has been impersonating him online, using his email address, and has even set up a website under his name. Jackson agrees to take on the case, but before he can start, he witnesses a road rage incident in which a wealthy businessman named Graham accidentally hits a pedestrian with his car. Graham is distraught and offers to pay for the victim's medical expenses, but he quickly disappears from the scene before the police arrive.

Unwilling to let the hit-and-run driver get away with his crime, Jackson starts to investigate Graham's background. He learns that Graham is the owner of several luxury car dealerships and is involved in a bitter divorce with his wife, Trudy. Jackson also discovers that Graham has a secret lover, a young woman named Samantha who works at one of his dealerships.

As Jackson delves deeper into Graham's life, he uncovers a web of lies and deceit that goes far beyond the hit-and-run incident. He discovers that Graham is heavily in debt and has been using illegal means to finance his failing business. He also learns that Samantha is not the innocent victim she appears to be, and that she has her own hidden agenda.

Meanwhile, Jackson continues to work on Harry's case, tracing the identity thief to a small town in the Scottish countryside. He discovers that the culprit is a teenage boy who has been using Harry's identity to create fake social media profiles and scam unsuspecting victims out of money.

As the two cases intertwine, Jackson is drawn into a dangerous world of greed and corruption. He must use all his skills as a detective and his instincts as a former cop to untangle the web of lies and bring the criminals to justice.

"One Good Turn (1)" is a gripping episode of "Case Histories" that showcases the talents of Jackson Brodie and the beautiful Scottish setting of Edinburgh and the surrounding countryside. With its complex plot, flawed characters, and unexpected twists, this episode will keep viewers on the edge of their seats until the very end.
