Zac Brettler, a London teenager born in 2000 to an upper middle-class family, tragically died in 2019 after falling from a luxury apartment beside the River Thames. His death unveiled a hidden life where he pretended to be "Zac Ismailov," the son of a deceased Russian oligarch, to an extent where he sought to inherit hundreds of millions of dollars. This elaborate deception led him to become entangled with older, unscrupulous individuals, including cryptocurrency trader Akbar Shamji and gangster Verinder Sharma, who were reportedly seeking a share of his fabricated inheritance.

Brettler's fascination with wealth and his compulsive lying began in his school years, driven by London's changing landscape, which had become a hub for conspicuous consumption and global plutocracy. He was drawn to the "swaggering hustle culture" prevalent in the city and sought to emulate the lavish lifestyle of real Russian oligarchs' children. His family, including his mother, who hired a therapist for his "strange behavior," and his brother, who was appalled by his "wannabe gangster" persona, were largely unaware of the extent of his double life.

His final moments were spent in an apartment with Shamji and Sharma, who were reportedly beginning to realize his claims of being a billionaire heir were false. The Metropolitan Police's investigation into his death in 2019 resulted in an "open verdict" in 2022, failing to definitively determine the cause. The case highlighted not only the complexities of London's financial landscape, where the super-rich often operate with impunity through shell corporations and trusts, but also concerns about the incompetence of the police in addressing the circumstances surrounding his death.
