Private investigator Leo Finn's quiet life shatters when a terrified woman calls him to the abandoned Carmody mansion, claiming she witnessed a murder. Instead of a body, he finds a tarnished locket tied to a moving rocking chair—and a cryptic text about a thirty-year-old secret. Digging into the cold case of heiress Eleanor Carmody, Leo uncovers lies, powerful enemies, and a witness who's been hiding in plain sight. With humor, heart, and help from his sourdough starter Bartholomew, Leo races to expose the truth before the past buries him too.
