A duke drifting into the drug trade may sound like pure Guy Ritchie fantasy, but that is the irresistible premise behind The Gentlemen, the Netflix action comedy returning today for its second series.
At the centre of the story is Edward “Eddie” Horniman, the newly installed Duke of Halstead, played by Theo James, who discovers he has inherited far more than a financially troubled ancestral seat: beneath the family’s country estate lies an enormous hidden cannabis farm.
Eddie initially tries to disentangle himself from the illicit operation, but those efforts quickly collapse. Before long, he is dragged into the high-stakes machinery of organised crime — and, to his surprise, finds he has a natural talent for it.
The storyline is deliberately extravagant, as viewers would expect from Ritchie’s stylish criminal underworld. Yet parts of the premise are not as far removed from real life as they may appear.
Across Britain, police have uncovered genuine drug production sites inside or around grand historic properties, including a £2.2 million Georgian mansion and a 102-room Welsh estate that once welcomed King Charles.
In one striking case, a cannabis setup discovered at a Grade II-listed country house in Cumbria was estimated to be worth £5.2 million — roughly £200,000 more than the annual payment made to the fictional aristocratic landlord at Halstead in the Netflix series.
Such cases underline a more serious reality behind the drama: many of Britain’s country houses are under intense financial strain, caught between soaring running costs and the decline of older, more reliable sources of income.
Maintaining these vast estates is a costly business, with yearly bills for staff and upkeep sometimes exceeding £1 million — and that is before owners confront major restoration projects, from structural repairs to the replacement of an entire roof.

Let’s start at Moulton Grange, a sprawling manor house in Northamptonshire which hosts luxury weddings and corporate events.
Boasting 28 acres of landscaped grounds, it has been praised by guests as ‘the perfect venue’ and ‘simply magical’, while one happy couple said it ‘exceeded all our expectations’.
But it appears to have been hiding a darker secret, with investigators seizing more than 12,000 doses of illegal weight-loss injections from a suspected black-market drugs factory operating inside the house.
During a raid on May 28, officers from the Medicines and Healthcare products Regulatory Agency (MHRA) arrested two 29-year-old men, who were later released.
The MHRA claimed Moulton Grange was being used as a ‘large-scale facility to manufacture, assemble and distribute unlicensed weight-loss medicines, including retatrutide and tirzepatide, as well as peptide products’.
Tirzepatide is the active ingredient in Mounjaro, while retatrutide is an experimental treatment still undergoing clinical trials.
The MHRA described the raid as the UK’s largest seizure of unlicensed weight-loss injections and said it was targeting an ‘organised criminal group’.
The property is owned by Faiz Hameed, 61, and Rashda Hameed, 59, who are also directors of Moulton Grange Limited, a property management company. It is unclear whether they live at the estate and they made no comment in July when news of the seizure was made public.
Moulton Grange is considered an ‘outstanding’ example of an English country house, featuring a grand Georgian façade and a sumptuous interior complete with chandeliers, period furnishings and ornate carved fireplaces.

Constructed mainly in the late 18th and early 19th centuries, the stately pile is Grade II-listed and was last sold for £2.2million in 2017, according to Land Registry records.
Another stately home, Plas Glynllifon near Caernarfon in North Wales, was raided by police searching for drugs a month earlier in April.
The historic mansion, once owned by Lord Newborough and host to King Charles’s investiture ball when he was Prince of Wales, was found to contain a major cannabis-growing operation.
Officers uncovered cannabis plants across 12 rooms on the top floor of the building, North Wales Police said.
The empty mansion, which hosted the investiture ball following Charles’s ceremony at Caernarfon Castle in 1969, was put on the market for £2million in 2024 but is understood to have since been withdrawn from sale.
Superintendent Arwel Hughes said: ‘We uncovered a grow, which was on the top floor of the building.
‘We estimate around 12 rooms with grows in them and they were fairly mature plants.’
Built in 1836, the manor house previously operated as a wedding venue and was later bought with plans to transform it into a luxury hotel.
It was sold in 2020 after entering receivership following a failed attempt to turn it into a high-end hotel.
The mansion was then bought by a Manchester-based developer before being put back on the market in 2024 for £2million. It appears to no longer be for sale.

The surrounding park remains open to visitors, with tickets costing £6 for adults and £4 for children.
On Tuesday, officers said they had arrested a 70-year-old man on suspicion of allowing the property to be used for the supply of cannabis before releasing him on bail.
A 38-year-old man, arrested on suspicion of supplying cannabis, was released but remains under investigation.
While Plas Glynllifon limped on as a visitor attraction, 23,000-square-foot The Flass in Cumbria was left derelict after falling into the hands of a new owner who acquired it as part of a divorce settlement.
Originally built by tea and opium traders Lancelot and Wilkinson Dent of Dent & Co in the mid-19th century, the mansion was rented for a bargain £5,000 a month to a London-based drugs gang, who filled its 52 rooms with a cannabis crop worth an estimated £5million.
When police raided the house in the quiet village of Maulds Meaburn, they discovered ducting, cabling and other equipment believed to have been used to cultivate more than 260kg of cannabis.
Gang members Dean Cameron, 53, of London, and David Lawrence, 32, of Ilford, were each jailed for eight years.
Mark Gallagher, 49, of Wolverhampton, and Philip Branigan, 32, of Banstead, Surrey, were jailed for seven years, while Charles Neophytou, 47, of Banstead, was sentenced to five years and six months.

Each was either convicted of, or pleaded guilty to, conspiracy offences.
Tim Evans, prosecuting, told the court in 2015: ‘This was cannabis growing on a massive scale. It is not the self-amateurish cultivation of cannabis on a window ledge or in the converted loft of a house. This was growing in a stately home.
‘Flass is a beautiful house, Grade II-listed because of its historical and architectural significance. It is a secluded house, no doubt why it was chosen for this criminal enterprise.’
In 2019, the house was sold for just £500,000, to the delight of local villagers who had watched it fall into disrepair.
By contrast, Badminton House, where The Gentlemen is filmed, is a thriving country estate run by Henry ‘Harry’ Somerset, the 12th Duke of Beaufort, and his wife Georgia.
The couple cover the estate’s costs by hosting a string of prestigious events, including the Badminton Horse Trials and the Royal Horticultural Society Badminton Flower Show, alongside welcoming productions such as Netflix dramas.
If only the fictional Duke of Halstead could follow their example.
