Reread to see if it was as bad as I remembered and this time couldn't finish it.
The book is full of plot holes and illogical thoughts and actions.
TSTL heroine, who e.g. accepts a tel. nr provided by a guy claiming to be an FBI agent to check up on him instead of an ID. When told by an FBI agent to drive away if she hears shots, she instead gets out of her car to watch the firefight between the agent and the person trying to kill her from a balcony. She also keeps on saying she wants to go to a hotel, claiming it is safer than her house because the killer will not be there.
The FBI agent isn't much smarter either, e.g. insisting the killer is a serial killer even when every bit of evidence points another way.
