From The Perry Mason TV Show Book
Hitchhiker Claire Olger is charged with grand theft auto and manslaughter when the driver of the car she's riding in hits a truck, killing the truck driver, then flees the scene, leaving Claire to take the blame.
Perry agrees to help Claire and eventually does locate the missing driver. Trouble is, he's dead. Burger drops the previous charges against Claire and files a new one: first degree murder. A second murder only complicates things more.
