A Christmas Revelation by Anne Perry

Worm is out making his rounds in the neighborhood when he sees a beautiful woman.  He begins following her until two men show up and grab her.  He's got to save her so he goes home and tries to convince the old accountant to go with him.  Squeaky would rather not, but there's no changing worm's mind...

Ballantine Books and Edelweiss gave me the opportunity to read this book for review (thank you).  It has been published so you can buy a copy now.

Squeaky uses his many contacts to find out who they are and what they are doing.  They're after gold and once they find it, they intend to kill the woman.  Worm knew she was in danger.  So Squeaky comes up with a plan.  He'll imitate her dead father and make them think he's a ghost.  Worm and the lady will tag along and make sure they're going where they want them to.  Worm learns his pretty lady is not as nice as he thought:  She wants revenge.

It has a very interesting ending.  It's fitting but it's not kind.
