In the early hours of a morning in 2019, a 19-year-old named Zac Brettler stepped onto the balcony of a luxury apartment in central London and fell into the River Thames. He did not survive the plunge. His body was found face-down in the muck along the riverbank shortly after dawn, marking the tragic end to a life that had recently spiraled into a complex web of deception.
Brettler, a recent graduate of an expensive private school and the grandson of a prominent London rabbi, had been living a secret existence unknown even to his parents. In the weeks leading up to his death, he had convinced a feared local gangster that he was “Zac Ismailov,” the son of a wealthy Russian oligarch poised to inherit a fortune exceeding $270 million. The apartment from which he fell was valued at more than $5 million, owned by a Saudi princess but occupied by the gangster, Dave Sharma.
The circumstances surrounding Brettler’s death have long been a subject of speculation. While the London Metropolitan Police investigated the incident, many questions remained unanswered for the family. Was it suicide, or was it a desperate attempt to escape a dangerous situation? These uncertainties form the core of London Falling: A Mysterious Death in a Gilded City and a Family’s Search for Truth, the gripping new book by Patrick Radden Keefe.
A Teenager’s Dangerous Double Life
Keefe, a staff writer for The New Yorker known for his meticulous narrative nonfiction, uses Brettler’s story to peel back the layers of a city often perceived as a stable financial capital. The investigation reveals a young man caught in an aspirational trap. Brettler came from a comfortable background—his father worked in finance and his mother wrote for the Financial Times‘ How To Spend It magazine—yet he harbored ambitions that far outstripped his reality.
According to Keefe’s reporting, Brettler told school friends that his family’s wealth was “not enough” and that he wanted to be “bigger.” This drive led him to construct a false identity, complete with claims that his father was an arms dealer and that the family lived next to Hyde Park. While schoolmates often recognized these claims as fabrications, Brettler managed to deceive Sharma, a seasoned criminal figure.
The dynamic between the teenager and the gangster suggests a collision of two different types of imposters. Keefe notes that by the time Sharma took Brettler under his wing, the gangster was an aging figure who had lost some of his edge, potentially viewing the teenager’s fictitious fortune as a final score. Associates of Sharma later indicated that once the con was revealed, Brettler’s survival was unlikely.
London as a Global Safe Deposit Box
Beyond the specific tragedy of one family, London Falling examines the broader ecosystem that allowed such a scenario to unfold. Keefe describes modern London as a “safety-deposit box for the global, uber-rich,” where unexplained wealth is often stashed in multi-million dollar properties that sit empty for much of the year.
This environment creates a backdrop where legitimacy is often performative. As Brettler’s mother, Rochelle, discovered while digging into her son’s secret life, the city harbors an underworld that exists alongside its glittering cultural institutions. “This whole world we didn’t know about,” she told Keefe, describing it as an underworld “on our doorstep.”
The narrative draws parallels to literary figures like Jay Gatsby and Tom Ripley, exploring the human tendency to embellish identity in the pursuit of status. However, unlike the fictional strivers of the past, Brettler’s story plays out against the particularly real mechanics of money laundering and organized crime in a post-Brexit financial hub.
The Search for Truth
Patrick Radden Keefe has established himself as a master of using true crime to explore social pathologies. His previous works, including The Snakehead and the 2019 bestseller Say Nothing, utilized specific criminal cases to illuminate larger political and historical conflicts. In Say Nothing, he effectively solved a decades-old cold case in Belfast to illustrate the toll of the Troubles.
With London Falling, Keefe applies similar rigor to the Brettler case. The story remained largely absent from London papers at the time of the incident in 2019, only breaking into wider public consciousness through Keefe’s reporting in The New Yorker nearly five years later. The book documents the Brettler family’s own investigation, as they sought to understand how their son ended up in a fifth-floor apartment with a known criminal.
The account suggests that both the victim and the antagonist were products of a “glitzy, mercenary aspirational culture.” Sharma, who pretended to be a mentor, and Brettler, who pretended to be an heir, were both caught in a system that rewards appearance over substance.
What Comes Next
As London Falling reaches bookshelves, it brings renewed attention to the unresolved questions surrounding Zac Brettler’s death. While the criminal justice system has moved on, the book serves as a definitive record of the events leading up to that morning on the Thames.
For the Brettler family, the publication marks the culmination of a long search for answers in a city that often keeps its secrets well. Keefe’s work ensures that the story of Zac Brettler is no longer just a footnote in the police logs, but a central case study in the costs of London’s gilded economy.
Readers interested in the ongoing discussion regarding financial transparency in the UK can follow updates from the National Crime Agency, which continues to monitor unexplained wealth orders. For now, the story stands as a somber reminder of the dangers lurking beneath the surface of the capital.
