Defense attorney Mickey Haller returns with a haunting case - the murder of a former client.
Mickey Haller gets the text, 'Call me ASAP - 187', and the California penal code for murder immediately gets his attention. Murder cases have the highest stakes and the biggest paydays, and they always mean Haller has to be at the top of his game.
When Mickey learns that the victim was his own former client, a prostitute he thought he had rescued and put on the straight and narrow path, he knows he is on the hook for this one. He soon finds out that she was back in LA and back in the life. Far from saving her, Mickey may have been the one who put her in danger.
