Scammer Payback. A Nadine Singh Thriller, #3

The law can't touch them. But she can. Nadine Singh fought hard for her quiet life in the California suburbs. As a former nun with a blood-soaked history of vigilante justice, she thought she had finally traded her knife for a trowel. But silence is a luxury she can't afford when Margaret Chen, an elderly widow, is left destitute by a ruthless romance scammer. The police call it a "civil matter" buried under untouchable jurisdictions.
Nadine calls it a target. Shedding her retirement, Nadine follows the digital trail to the sweltering heat of Accra, Ghana. There, she locates the nerve center of the operation: a gleaming, fortress-like high-rise owned by the enigmatic Philip Sorkin. To destroy the rot, she must enter the beast's belly. Posing as a naive, wealthy traveler, Nadine infiltrates Sorkin's inner circle. However, the mission quickly escalates beyond simple restitution.
While hunting for Margaret's savings, Nadine uncovers a terrifying truth: Sorkin isn't just running a scam farm. He is financing a global surveillance algorithm designed to weaponize personal data on a mass scale. Suddenly, Nadine is miles from home, outnumbered by a private army, and stung by the betrayal of the one local ally she trusted. Trapped in a deadly game of cat-and-mouse across two continents, Sorkin believes he has cornered a helpless woman.
He doesn't realize he just invited the tiger to dinner.
