Capital

Pepys Road is a residential street in South London whose houses, built in the late nineteenth century for lower-middle-class families, have by late 2007 become worth millions of pounds. The novel opens with a hooded young man filming the houses at dawn. Over the months that follow, residents begin receiving postcards showing photographs of their own front doors, each bearing the message "We Want What You Have." This mysterious campaign, which grows increasingly sinister, connects the lives of the street's disparate inhabitants as Britain slides toward financial crisis.

Petunia Howe, an 82-year-old widow at number 42 and the street's longest-tenured resident, finds the postcards amusing. She has been experiencing fainting spells, and a hospital consultant raises the possibility of a brain tumor. When she faints in the corner shop, Ahmed Kamal, the shop's owner at number 68, walks her home, establishing his decency.

At number 51, Roger Yount, a 40-year-old banker at Pinker Lloyd, calculates whether his annual bonus will reach one million pounds. His lifestyle, including the house, a country property, luxury holidays, private school fees, and nannies, requires the bonus just to break even. His wife Arabella, frustrated by Roger's obliviousness to the demands of childcare, secretly plans to abandon him over Christmas, forcing him to manage their two young sons, Conrad and Joshua, alone. Roger's deputy Mark, a quietly intense former mathematics PhD student, understands their department far better than Roger does and privately considers Roger a lightweight.

Ahmed runs the shop with his two brothers. Shahid, the middle brother, is a free-spirited drifter who once traveled to Chechnya as a teenager but returned disillusioned. Usman, the youngest, has grown increasingly devout. After Friday prayers, Shahid encounters Iqbal Rashid, a Belgian-Algerian man he knew briefly during his time in Chechnya. Despite a vague unease, Shahid gives Iqbal his phone number and later allows him to stay at his flat. The visit stretches from days into months.

Quentina Mkfesi, a Zimbabwean political science graduate, works illegally as a traffic warden under a fake identity. She fled Zimbabwe after being beaten for political activism and applied for asylum in the UK, but her claim was rejected. Because she cannot currently be deported, she exists in legal limbo, living in a charity hostel with other stateless women.

Freddy Kamo, a 17-year-old football prodigy from Senegal, arrives in London with his father Patrick, a police sergeant, to begin his professional career at a Premiership club. Mickey Lipton-Miller, the club's fixer, manages their transition. Patrick secretly hates everything about the city: the cold, the loneliness, the distance from his wife and daughters.

Smitty, a famous anonymous street artist whose real name is Graham, is Petunia's grandson. He visits her and discovers the accumulating postcards and a DVD, intrigued by their art-like quality, and takes them back to his studio. Zbigniew Tomascewski, a Polish builder whom Arabella calls "Bogdan," lives frugally in Croydon, saving money to start a business with his father in Warsaw. He dreams of returning to Poland a wealthy man.

Roger learns his bonus is only £30,000 because the bank's Swiss subsidiary has suffered massive losses from subprime mortgage exposure. He is physically sick with shock. Arabella then executes her plan, disappearing on Christmas Eve. A Hungarian nanny named Matya, orphaned at 10 and seeking a bigger life in London, is hired through an agency and bonds instantly with the children. Roger seizes on her arrival as leverage, implementing austerity measures against Arabella when she returns. Their relationship cracks fundamentally.

In the spring, Petunia's tumor is confirmed as inoperable. She refuses chemotherapy and declines steadily. Her daughter Mary moves from Essex to care for her. Detective Inspector Mill is assigned to investigate the "We Want What You Have" campaign but struggles to identify a clear crime. Mark begins secretly collecting colleagues' passwords and making unauthorized trades, aiming to generate £50 million in hidden profits and claim Roger's job.

Freddy makes his first full start in a Premiership match, only to have his leg catastrophically broken by a tackle within minutes. Visiting number 42, Zbigniew accidentally opens the bedroom door where Petunia lies dying, an encounter that profoundly shakes him. Petunia dies at home in late spring with Mary at her bedside. Mary hires Zbigniew to renovate the house for sale, and while stripping wallpaper he discovers a hidden compartment containing £500,000 in cash left by Petunia's late husband, Albert Howe.

In August, the campaign escalates sharply. A blog appears featuring photos of the houses defaced with abusive graffiti, dead blackbirds arrive in envelopes, and every car on one side of the street is keyed in a single night. Separately, armed police raid the Kamal family home at dawn. Shahid is arrested under the Terrorism Act. His interrogators believe Iqbal was planning to blow up the Channel Tunnel using stolen Semtex, a plastic explosive, and they suspect Shahid because Iqbal used his internet connection. The family engages Fiona Strauss, a prominent human rights solicitor. Shahid is held for 19 days, finding spiritual strength through prayer, before being released without charge.

On 15 September, Mark's unauthorized trading is discovered; he is £30 million down and is arrested for fraud. Roger is dismissed for gross negligence in failing to detect the scheme. Walking home, he sees a headline announcing that Lehman Brothers is on the brink of collapse. Pinker Lloyd itself soon collapses entirely.

Quentina's asylum case is assigned to a conservative immigration judge, and her application is rejected. She is sent to a detention centre, where she sustains herself with the conviction that the experience will not last forever.

The Younts put their house on the market. Matya is given notice, grieving not for the job but for losing Joshua, whom she has come to love deeply. Zbigniew, now dating Matya after engineering their meeting, confesses about the money, and she insists he return it. They travel to Mary's home in Essex, where Mary recognizes the suitcase: Her father hoarded cash for a dramatic revelation that never came because he died suddenly. Mary's husband Alan explains that the old banknotes can be redeemed at the Bank of England, but tax investigations would consume most of the value. Zbigniew and Matya begin a happy relationship and look for a flat together. His plan to return to Poland shifts; London becomes the place where he lives rather than merely earns.

Freddy's insurance claim is settled for £5 million on the condition he never plays professional football in Europe, the Americas, or Asia but is permitted to play in Senegal. He and Patrick can go home.

Shahid confronts Usman, having deduced that his brother created the original blog as a protest against Western materialism. Usman stopped updating it, but someone else took over and made it darker. Smitty's identity is exposed by the Evening Standard, destroying the anonymity central to his art. He contacts Mill and identifies his fired former assistant, Parker French, as responsible for the escalated campaign. Parker had seen the original materials in Smitty's studio, copied the content, relaunched the blog with abusive additions, and committed the vandalism as revenge for being sacked. Mill arrests Parker, who confesses to everything, including keying the cars.

On his last day in the empty house, Roger walks through every room. Arabella shows no sign of the fundamental change he desperately wishes for. As he drives away and catches a final glimpse of his old front door, his only thought is a desperate promise: "I can change, I can change, I promise I can change change change."
