What this book teaches
Most people don't lose money to a master criminal. They lose it a few dollars at a time — the forgotten subscription, the padded invoice, the "guaranteed 12%" pitch, the fine-print clause that flips a deal, the fake-invoice email that hit Facebook and Google for $100M. Book 3 turns the numbers-detective eye of Books 1 and 2 on your own paperwork. You follow Nadia — an ordinary earner with a job, a landlord, a phone plan, and a small side hustle — as she catches what everyone else missed. Every chapter is one of her cases; every case is one skill you rehearse on your own statements.
A red flag is a question, not a verdict. This is education on how to check your own money — not accounting, tax, legal, credit, or investment advice. Every unusual figure is a reason to slow down, reconcile, and ask, never proof of wrongdoing on its own.
