When wealthy philanthropist Richard Hawthorne is found dead in a locked room under mysterious circumstances, private investigator Grace Mitchell is hired to uncover the truth. At first glance, Hawthorne’s life seems admirable—an influential businessman and generous benefactor to various charities—but as Grace delves deeper into his past, she uncovers a darker side.

Beneath his polished image lies a trail of deceit, fraud, and broken promises, leaving a long list of potential suspects. From estranged family members and business rivals to former lovers and betrayed investors, everyone in Hawthorne's life had something to gain from his demise. But as Grace pieces together the puzzle, she realizes this case is far more complex than a simple murder. Her investigation uncovers a web of corruption, blackmail, and conspiracy involving high-powered individuals who will stop at nothing to keep their secrets buried.

The deeper Grace digs, the more dangerous her quest becomes. Mysterious threats emerge, and soon her own life is at risk. With each new revelation, she edges closer to the truth—but the closer she gets, the more she realizes that no one, not even those she trusted, can be taken at face value. In Broken Promises betrayal runs deep, and the cost of uncovering the truth may be higher than Grace ever imagined. As the conspiracy unravels, she must confront not only the killer but also her own principles, knowing that some secrets are better left buried.
