A Is for Acid

The movie is set across three main locations: a rural Yorkshire village where Haigh is raised, wartime London, and Kensington where his criminal enterprise operates. Key settings include a workshop used for the murders and the upscale Onslow Court Hotel, where Haigh maintains a respectable facade. The contrast between provincial quiet and urban bustle underscores the gap between his appearance and his crimes.

The events unfold from the late 1930s through the 1940s, encompassing World War II and the VE Day period. The war provides cover for Haigh's scams as public attention is diverted, allowing him to build wealth through fraud and murder. Postwar Britain frames his eventual downfall as social norms shift and the truth emerges.

The movie explores three central themes: Greed, as money and social climbing drive Haigh's murderous spree; Deception, as he constructs elaborate alibis and personas to mask his crimes; and Manipulation, as he exploits trust, friendship, and professional connections to lure victims. The story examines how surface credibility masks deadly intent.

John Haigh (played by Martin Clunes) is a calculating, charismatic killer who cloaks murder in the language of business and invention. His relentless pursuit of wealth and status drives a string of brutal acts, revealing a cold willingness to exploit and eliminate anyone who stands in his path. He presents himself as a harmless inventor while committing murders for financial gain.

Yes, the movie is a dramatized account of John Haigh, the infamous British "acid bath murderer" who killed several women in 1940s Britain and attempted to dissolve their bodies in vats of acid. His downfall came when a pathologist discovered undissolved gallstones in the residue, exposing his crimes.

The Onslow Court Hotel is an upscale residence in Kensington where Haigh presents a respectable facade while plotting his crimes. It serves as his base for maintaining appearances and social connections that further his schemes. Fellow resident Olive Durand-Deacon's disappearance from this hotel ultimately triggers the investigation that exposes Haigh.

Olive Durand-Deacon (played by Matyelok Gibbs) is a fellow resident of Onslow Court Hotel whose disappearance triggers the investigation that ultimately exposes Haigh. Her case becomes the catalyst for the police inquiry and the killer's eventual downfall, making her pivotal to the story's resolution.

Gillian Rogers (played by Keeley Hawes) is Haigh's early romantic connection who becomes entangled in his schemes. She is drawn to his intellect and confidence, yet she gradually confronts the moral implications of his actions as the danger and deceit mount around her.

Donald McSwan (played by Neil McKinven) is a successful property businessman whose elderly parents fall under Haigh's influence. Haigh murders him to seize control of his affairs and wealth, demonstrating Haigh's ability to manipulate and kill trusted friends for financial gain.

The war provides essential cover for Haigh's criminal activities. As families lose focus on potential dangers during wartime, Haigh exploits the distracted social climate to carry out his scams and build wealth. Postwar Britain then frames his rise and eventual downfall as social norms shift and the truth finally emerges.

The movie maintains a consistently dark and chilling atmosphere, reflecting the serious and disturbing nature of a serial killer's crimes. The tone is described as grim and clinical, offering a factual depiction of cold-blooded murder for financial gain without redeeming qualities or hope for the protagonist.
