The zebra-striped hearse

A private investigator is hired to investigate a man's true intentions before a marriage, and the case spirals into a murder investigation across multiple locations — classic hardboiled noir structure. The tone is gritty and tense rather than cozy or lighthearted, and the mystery is a genuine whodunit rather than a procedural. Moods reflect the dark, paranoid atmosphere of a man hunted by a mysterious group, and the melancholy of a man who has lost his wife and is still haunted by her.
