A Novel
In New York Times bestselling author Allison Brennan’s latest Angelhart Investigations novel, Margo finally has a new lead in the case that tore her family apart.
Private investigator Margo Angelhart has recently rejoined her family’s PI business, but she never forgot the reason she walked away. Three and a half years ago, her father, Dr. Cooper Angelhart, pled guilty to killing his colleague. While she never believed he was guilty, her mother, Ava, refused to help investigate and wouldn’t explain why.
When a nurse who once worked with Cooper reaches out, Margo leaps at what could be a potential lead…only to stumble across the nurse’s grisly murder. Then, Cooper is mysteriously transferred to a penitentiary out of state in the middle of the night, and Ava finally discloses why her husband confessed to a murder he didn’t commit.
Now the entire Angelhart family must fight to clear Cooper’s name. But every step they take drags them deeper into a deadly conspiracy…and into the crosshairs of some very powerful people with fortunes on the line. They’ve killed to keep their secrets before. And this time, the target is an Angelhart.
