The Auditor's Secret Ledger, Auditing My Husband's Betrayal

From the back cover

For three years of marriage, Chloe has never touched her husband Julian's briefcase. He is a senior forensic auditor, and she respects his confidentiality. Then he forgets it before a business trip and asks her to mail it to his hotel. The zipper is open, and a manila envelope slides out: a custody agreement between Julian Vance and a woman named Hailey, for a child born in March 2021 — months before Chloe and Julian married.

She says nothing and mails the briefcase. Then she begins to audit her own life. Water bills show almost no usage during his supposed trips. Bank statements reveal a fixed monthly transfer marked only "Expenses," and quarterly purchases at a baby boutique that track a child's growth from formula to size 10 shoes. His explanations are smooth, his phone is impossibly clean, and a three-hour flight does not match the city he claimed.

Julian is a forensic auditor who knows exactly how to leave no trace. Chloe is quietly learning to read the ledger he never meant her to see.
