An all-female criminal enterprise operating from Victorian London to the 1950s. Three stages of money laundering. Eighty years without a single compliance check.
AML · Dark Tales · London Criminal History
She appeared in the dock at Southwark Police Court in a splendid black velvet cloak trimmed with fur, over a black silk dress, her head adorned by a broad-brimmed Rembrandt hat boasting five ostrich feathers. On her fingers glittered seven diamond rings, valued by one journalist at over three hundred pounds, at a time when a working man's wage was less than two pounds a week.
Mary Carr, Queen of the Forty Thieves, was about to be sentenced for kidnapping. The source of the rings on her fingers, the fur on her cloak, the silk of her dress nobody asked.
The Forty Elephants were an all-female criminal enterprise based in the Elephant and Castle area of south London. Active from at least the 1870s and by some accounts considerably earlier, the gang operated under a succession of leaders known as queens until the 1950s. Their primary method was organised shoplifting from high-end stores in London's West End and, in their later years, from major retail centres across England. Their secondary methods included blackmail, fraudulent references to obtain domestic employment before looting their employers' homes, and an extensive network for receiving and distributing stolen goods.
This blog draws directly on Brian McDonald's book Alice Diamond and the Forty Elephants (Milo Books, 2015), which is the authoritative published account. McDonald researched the book through police reports, court records, contemporary newspaper archives, unpublished family histories, and the notes of crime journalist Stanley Firmin and gang associate Dan Johnston. Where specific historical claims are made they are referenced to that source. Secondary sources used include the London Museum's published account and Historic UK. A Thousand Blows, the Disney+ drama created by Steven Knight (2025), is drama inspired by the history rather than a documentary account. It is not used as a source here.
This is another historical tale through the lens of modern day AML. This is done to provide an accessible illustration of application of old facts and factors into the modern day compliance framework, it presents less friction to understanding key concepts.
The regulatory framework applied is the Proceeds of Crime Act 2002 (POCA 2002), the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (MLR 2017), and the LSAG Anti-Money Laundering Guidance for the Legal Sector 2025 (LSAG 2025, in force from 23 April 2025). The three-stage conceptual model of placement, layering and integration is the FATF framework. It is not terminology that appears in the MLR 2017 itself, and is applied here as an interpretive structure.
The FATF Three-Stage Model applied to 1870s to 1950s London
The Elephants Ran All Three Stages Simultanously. Nobody Noticed for Eighty Years
The FATF framework identifies three stages in the movement of criminal proceeds into the legitimate economy. The Forty Elephants did not know these terms. But their operation anticipated each one.
The criminal property is generated
Furs, silks, jewellery, leather goods taken from the high-end stores of the West End. Each item is criminal property within the meaning of Section 340 of POCA 2002 from the moment it leaves the store. The "clouting" methods clothing modified with hidden pockets, underskirts sewn into large repositories, muffs and hats adapted for concealment are the mechanics of placement.
McDonald records that the women "rarely wore what they stole, possibly to avoid the items being recognised, but bought high fashion from the proceeds of their larcenies." The criminal property enters circulation at the point of theft and moves immediately to the layering stage.
Modern equivalent: cash or assets from criminal activity entering the financial system at the point of generation.
The goods move through the fence network
McDonald documents the distribution network in detail. Furs went to East End furriers who removed labels and remodelled merchandise so it could not be identified. Jewellery and antiques went to Caledonian Market in Islington, which before 1995 operated under the ancient law of market ouvert, allowing ownership of goods to transfer between sunrise and sunset without questions as to provenance. Home goods went to street markets. Each transaction added distance between the criminal property and its origin.
The most sophisticated layering element: a woman receiver in the Elephant and Castle area who maintained secret cupboards and double floors holding, as crime journalist Stanley Firmin recorded, "ledgers of transactions entered as legitimate purchases with fake names and addresses." McDonald identifies her as Ada Johnston. The documentation was created specifically to defeat inquiry.
Modern equivalent: multiple transfers designed to obscure the origin of funds, with false documentation to support the appearance of legitimate activity.
The proceeds re-enter the legitimate economy
Alice Diamond wore furs and diamond rings. She drove fast cars. She moved through Soho's fashionable nightclub scene. The women "partied hard in the streets where they grew up. They went to the West End dressed in highest fashion: gorgeous fur coats, tailored suits and expensive jewellery." McDonald records this directly.
The proceeds of the criminal enterprise, having passed through the fence network, were spent in ways indistinguishable from legitimate earnings. This is the integration stage. It is also where the source of wealth question arises and where, in the absence of any regulated professional ever asking it, it went permanently unanswered.
Modern equivalent: criminal proceeds reintroduced into the economy through luxury spending, property, or investment that cannot be traced to the underlying crime.
Chapter One · The Carr Era
The First Queen The Foundation of the Enterprise
Mary Carr's convictions began in 1876, when she was cautioned at Westminster as a fourteen-year-old for stealing from shops. She was described in a 1900 police report as "one of the most dangerous women in the metropolis and Queen of the Forty Thieves" and as "a good-looking woman who had modelled for important artists but who led a gang of obedient teenage females." She married Thomas Crane on 3 September 1888 and operated from homes in Southwark. Her notoriety was sufficient to inspire a West End theatre production, The Worst Woman in London, which opened at the Standard Theatre in 1899.
What McDonald's primary research establishes about the Carr era is important for historical accuracy. The gang targeted "large stores of the West End of London." The specific stores that McDonald names in the context of the gang's operations during this general period before the grand Edwardian rebuilding of the major department stores include Whiteleys in Bayswater, which had been trading since 1863, and Army and Navy Stores. Harrods is named in McDonald's account in a 1908 context (a sable muff stolen, with the store described as "attaching considerable importance to the arrests"). Selfridges did not open until 1909. The rebuilt Debenham and Freebody Wigmore Street premises were completed in 1908. These are Alice Diamond era targets.
Carr was arrested in 1896 for the kidnapping of a six-year-old boy from Epsom Races and sentenced to three years' penal servitude. After her release she immediately resumed fencing stolen goods. In 1900, as Mary Crane, she was convicted of receiving and sentenced to two years in Wormwood Scrubs. McDonald records she "gave her age as twenty-nine but police said she was actually thirty-seven." She died in 1924.
Character One
Mary Carr
McDonald records that Mary Carr "stunned the magistrates at Southwark Police Court by appearing in a splendid black velvet cloak, trimmed with fur, over a black silk dress, her head adorned by a broad-brimmed Rembrandt hat boasting five ostrich feathers. On her fingers glittered seven diamond rings, valued by one journalist at over three hundred pounds, at a time when a working man's wage was less than two pounds a week."
She was a flower seller by documented trade. The gap between what she could legitimately earn and what she visibly possessed is the source of wealth problem made human.
Source of Wealth and the Assumption of Legitimacy
LSAG 2025 section 6.17 distinguishes between source of funds (where the specific money used in a transaction came from) and source of wealth (how the person accumulated their overall financial position). For higher-risk clients, both must be asked and both must be evidenced.
Mary Carr's source of wealth was entirely unexplained by her documented income. She worked as a flower seller and an artists' model. She presented at court in fur and diamonds. No regulated professional ever asked the gap between those two things to be explained. The Unexplained Wealth Order provisions of the Criminal Finances Act 2017 which allow the National Crime Agency to require a person who holds property disproportionate to their known income to explain the source of that wealth exist because this gap is precisely what the modern framework requires to be addressed. A UWO application requires that the person holds property exceeding fifty thousand pounds in value and that there are reasonable grounds to suspect the property derives from serious crime. Mary Carr's seven diamond rings, valued at over three hundred pounds in the 1890s, would have satisfied the threshold with ease.
The assumption of legitimacy she exploited in court the fur cloak, the silk dress, the ostrich feathers is the same tool every sophisticated financial criminal deploys. LSAG 2025 Chapter 4 requires professional scepticism: the discipline of evaluating evidence rather than presentation. Presentation is not evidence. Mary Carr demonstrated this more vividly than any modern compliance training module could manage.

Chapter Two · The Diamond Era
Alice Diamond The Industrial Scale of the Criminal Corporation
Born 1896, Lambeth Workhouse Infirmary · First mentioned in police records 1914-15 · Led the gang through the 1920s and 1930s · Died 1952 · Source: McDonald, pp. 101-210
Alice Diamond first appears in McDonald's records in December 1914, when four young women entered a hat shop on Oxford Street and stole hats, scarves and a gown. Three were arrested. One, who had taken a gown from the back of the shop during the confusion, escaped. Police records named her as Alice Diamond. By January 1915, she appeared at London Sessions charged with stealing from warehouses and was already described by police as "a skilful thief known as the Queen of the Forty Thieves, the head of a gang of robbers that congregated at Borough."
Under Alice Diamond's leadership the gang became what McDonald describes as operating "like a business corporation with a strict code of conduct." The gang was divided into cells McDonald records a "typical cell of four" each allocated to specific operations. There were formal rules of conduct, documented in what McDonald refers to as the "Hoister's Code" from Dan Johnston's unpublished notes. No drinking before a raid. No stealing from one another. Absolute loyalty enforced, when necessary, with violence.
The stores specifically documented by McDonald as targets in the Diamond era include: Selfridges on Oxford Street; D.H. Evans in Oxford Street; Debenham and Freebody; Harrods; Whiteleys; Bon Marche in Brixton; Swan and Edgar at Piccadilly Circus; and stores across Birmingham, Manchester, Leeds, Brighton, Cheltenham and other major towns. McDonald records one London store estimating losses of up to seven thousand pounds in goods over a year. The gang also used the Selfridges staff in October 1928, two shop assistants at Selfridges pleaded guilty to stealing goods from their employer to hand to "a gang of women terrorists" after being blackmailed into wholesale theft.
"The Queen of the Forty Thieves the most powerfully organised syndicate of shoplifters, pickpockets and blackmailers that was ever controlled by a woman had her court at the Elephant."
Daily Express, quoted in academic research published in the Women's History Review (2025), referring to Alice Diamond.
Alice Diamond
Alice Diamond is the integration stage made visible. McDonald documents her lifestyle directly: "gorgeous fur coats, tailored suits and expensive jewellery." She drove fast cars. She was a prominent figure in Soho's interwar nightclub scene. She was born in the Lambeth Workhouse Infirmary in 1896. Between those two facts lies a source of wealth question that was never asked by any regulated professional because no regulated professional was ever involved.
Source of Wealth, Complex Structures and Ongoing Monitoring
McDonald records the gang's operational structure in detail: cells of approximately four women, each allocated a specific area, each operating without visibility of the whole picture. This is the beneficial ownership opacity problem applied to an operational enterprise. No individual cell member could identify the directing mind above them. The directing mind controlled the distribution of proceeds through the fence network and did not appear in any visible record of any individual transaction.
Regulation 33(6)(a)(vi) of the MLR 2017 identifies corporate structures that are unusual or excessively complex given the nature of the company's business as a factor requiring consideration when assessing whether enhanced due diligence is needed.
The cell structure of the Forty Elephants multiple teams operating simultaneously across multiple locations, with a distribution network waiting to receive the goods and a directing mind sitting above the visible layer is the operational equivalent of a complex corporate structure with no obvious commercial rationale. The question a modern MLRO would ask is the same question nobody asked of the Forty Elephants: why is this so complicated, and who actually controls it?
Regulation 28(11) of the MLR 2017 requires ongoing monitoring throughout a business relationship, including scrutinising transactions for consistency with the firm's knowledge of the client and their profile. Alice Diamond led the gang from approximately 1915 to the 1930s.
A risk assessment appropriate to any one year of that period would have been wholly inadequate to the next, as the enterprise scaled, professionalised, extended geographically, and developed new revenue streams including blackmail and warehouse theft.

Ada Johnston and the Ledgers
The Fence Who Created False Records and What the Modern Equivalent Looks Like
McDonald's account of the fence network is one of the most instructive elements of the primary record for AML purposes. He draws directly on crime journalist Stanley Firmin's published account, Scotland Yard: The Inside Story, quoting Firmin's description of inspecting premises at the heart of the Elephant and Castle operation:
"Some little time ago in the Elephant and Castle area, I inspected some premises which were at the heart of a woman receiver who had just been arrested. The place was ostensibly a dress shop and the woman had built up quite a little reputation in the neighbourhood for her quiet way. For years she had been acting as receiver for no fewer than five notorious gangs of thieves. Thousands of pounds worth of stolen goods was found in her premises. Secret cupboards and double floors held ledgers of transactions entered as legitimate purchases with fake names and addresses."
Crime journalist Stanley Firmin, Scotland Yard: The Inside Story, quoted in Brian McDonald, Alice Diamond and the Forty Elephants (Milo Books, 2015), p. 76. McDonald identifies the receiver as Ada Johnston.
Documents Collected But Not Analysed A Pattern That Persists
The ledgers are perhaps the most instructive detail in the entire Forty Elephants record. Not because they were sophisticated forgeries. Because they were precisely the kind of documentation that satisfies a surface-level inquiry while concealing the underlying reality. The ledgers showed purchasing activity. They did not show the provenance of the goods recorded as purchased. The documentation was there. The analysis was not.
The SRA's 2024-25 AML annual report identified source of funds as one of the most consistently deficient areas in law firm compliance. The specific finding was that source of funds documents were "often collected but not analysed." A bank statement showing a balance is not evidence of source of funds. A document recording a purchase is not evidence that the purchase was legitimate. The obligation under LSAG 2025 section 6.17.2.1 is to evidence the underlying economic origin, not merely to file whatever documentation the client provides.
Any person who assisted in the acquisition, retention, use or control of criminal property knowing or suspecting it to be criminal property commits an offence under Section 328 of POCA 2002. The fences in the Forty Elephants' network were not simply market traders. They were, in modern legal terms, potentially concerned in arrangements to facilitate the retention and use of criminal property. Ada Johnston's ledgers were the mechanism by which that arrangement was made to look like a dress shop.

The Assumption of Legitimacy
The Gang's Most Powerful Operational Tool and the One the Modern Framework Is Built to Counter
McDonald records Detective Jack Capstick's description of the gang "descending on the West End like a gang of locusts in taxis and chauffeur-driven limousines and cleaning out a store inside one hour." They were dressed like the customers they were stealing from. McDonald notes they "went to the West End dressed in highest fashion: gorgeous fur coats, tailored suits and expensive jewellery." Staff who suspected poor women would not dream of demanding to search a well-dressed female customer's undergarments.
This is the assumption of legitimacy that the AML framework specifically guards against. It is not a Victorian curiosity. It is the permanent operating principle of sophisticated financial crime. The client who presents confidently, who has a smooth explanation for every question, whose documentation appears in order, is not for that reason a low-risk client. Professional scepticism is the obligation to look past the presentation to the evidence. Mary Carr wore fur and diamonds to her sentencing hearing. Alice Diamond wore tailored suits to hers. Both were convicted. Both continued operating.
LSAG 2025 Professional Scepticism and Presentation
LSAG 2025 Chapter 4 addresses the cultural requirement beneath all AML compliance work. Professional scepticism is not suspicion of all clients. It is the disciplined practice of evaluating evidence rather than presentation. The Forty Elephants built their entire operational model on the gap between how their queens presented and what they were actually doing. That gap is exactly the one the MLR 2017 obligation of verification, as distinct from identification, is designed to close. Identification establishes who someone says they are. Verification establishes independently that they are who they say they are. The Forty Elephants' queens were adept at identity. Verification would have been their undoing.
