In 'Not a Happy Family', the Mertons seem like a perfect wealthy clan, but their facade crumbles when the patriarch is murdered. The eldest daughter, Claire, isn’t actually a Merton—she was swapped at birth during a hospital mix-up, a secret her 'parents' kept to maintain appearances. The middle son, Peter, embezzled millions from the family trust to cover his gambling debts, while the youngest, Rachel, orchestrated a blackmail scheme against her own siblings.
The biggest twist? The late matriarch’s diary reveals she poisoned her first husband to marry into the Merton fortune, and her ghostwriter, who knew the truth, was paid off for decades. The family’s 'charitable foundation' was a front for tax evasion, and their prized vineyard? Built on stolen land. Every revelation peels back another layer of deceit, showing how far they’d go to protect their twisted legacy.
