Fog serves as both a literal and metaphorical element throughout the film. Physically, it conceals clues and provides cover for criminals operating in the city.

The city's haze wraps every clue in mist until the climax reveals the truth.

Foreshadowing: Early scenes establish the fog as a constant companion to the investigation, making it a recurring narrative device.

The film explores three interconnected themes. Mystery drives the plot through a puzzling hit-and-run murder and web of blackmail, with clues appearing and vanishing behind alibis and lies. Fog physically and atmospherically obscures the truth, creating cover for criminals. Secrets form the narrative backbone as blackmail, murder, and hidden identities are peeled back layer by layer, with those in power manipulating information to protect themselves.

Foreshadowing: The themes of mystery and secrets are established early as Heather refuses to accept the official story about her brother.

The conspiracy involves Christopher Hampden and his wife Margaret, who orchestrated Danny McMara's murder to silence him regarding their blackmail operation. Martin Sorrowby, Hampden's war partner who had cracked up and was institutionalized, was also involved. The web of secrets connects Danny to this criminal network, making him a liability that required eliminating through a staged hit-and-run.

The fog functions as a visual metaphor for moral ambiguity and hidden truth. Just as the London fog conceals the city's streets and landmarks, the conspiracy obscures the facts surrounding Danny's death. Investigators encounter dead ends and false leads, mirroring how physical fog guides people toward confusion. The clearing of the fog in the finale symbolically represents the revelation of truth and the restoration of justice.

Foreshadowing: The fog's presence throughout the investigation mirrors the gradual uncovering of truth from concealment.
