The Book Supremacy by Kate Carlisle

Brooklyn and Derek are in Paris enjoying their honeymoon.  As they walk along the book vendors along the street, they both find treasures.  She buys one for her husband and one for a friend back home.  Since she's a bookbinder, she can repair them both and doesn't have to spend much on them.  He buys one for her, too.  They think alike in many ways.  He's a retired spy although he won't talk about much.  When he meets a friend of his past, they both have a nice visit with Ned.  When they get back to their room, Derek is pretty sure someone broke in while they were gone.  But nothing is missing...

Berkley Publishing and Net Galley shared this book with for review (thank you).  It is due to be published June 4th.

When they go to visit another old friend who owns a spy shop, it's great fun to look over the the products he sells.  He even has escape rooms where everyone has to work together to find the solution to all the clues to get out.  While there, Brooklyn tells him about the book she bought in Paris.  It's a James Bond book and he asks if he can display it.  He'll put it in secure place where it can't be stolen.  She agrees.  But someone does try to steal it and kills the employee that tries to stop them.  They are covered with clothing so they can't been seen by the video cameras.  But Brooklyn and Derek are determined to find out who it was.

They find out that Ned is dead; he was murdered.  Then they find microfilm hidden in the book with names on it.  It seems these were spies that worked together on one job.  Someone is killing them one by one.  Who can it be?

With Derek having trouble at work, Brooklyn trying to create a fake book to take back to the store, one dead employee that Brooklyn was fond of, and the spy ring murders you'll be real busy reading this story and hoping they can find the killer.  It's gets even worse when they do...
