The Liar in the Library by Simon Brett

He came to the library to do a book presentation of his new novel and to sign books for those who bought.  When he offers to give her a ride home because it's cold out, she accepts.  Then he gropes her and talks about how long she's wanted him (NOT!) and she slapped him and got out of the car and walked home.  In the morning, his car is still in the parking lot and so's he.  But he's not breathing...

Severn House and Net Galley gave me the opportunity to read this book for review (thank you).  It will be published January 1st.

He had changed his name but he was the same old Al that screwed around when he thought he had opportunity.  Her problem was that she was the last one to see him alive and the cops think she must have killed him.  Even if she wanted to, she didn't.  It doesn't help when his first wife says she broke up their marriage and slept with him in the past.  It's not true but no one believes her except her good friends.  She finally decides the only way she's going to move from the suspect list is if she finds the murderer...

As she gathers information, she learns he was the same as he was in the past.  Why he made her his scapegoat she doesn't know.  She investigates with her neighbor and a man who had been at the library during his presentation.  When she finally breaks through to the solution, she's disappointed.  It's hard when someone you like does something bad.  The only good news is that she is not a suspect anymore...
