Obsession
Jonathan Kellerman
 Tanya Bigelow, a former patient, comes to Alex requesting help. She wants him and his friend Milo to investigate something her mother said on her death bed. Her mother told her that she did something terrible. No one believes that Tanya's mother Patty, who worked with Milo's partner at the hospital as a nurse, could have done anything terrible, but as the reader learns her past, it contains dark secrets. Alex has a new dog, Blanche, that Robin bought him after Spike died. Robin is living with Alex again.
