The Book Supremacy (Bibliophile Mystery 13)

Newlyweds Brooklyn and Derek are enjoying the final days of their honeymoon in Paris. As they're browsing the book stalls along the river, they bump into an old friend from Derek's spy days, Ned, and Brooklyn finds the perfect gift for Derek, an old first edition copy of a James Bond novel, The Spy Who Loved Me.
Once they're back home in San Francisco, they visit a spy shop Ned told them about. Owen, the owner, is thrilled to see his old buddy Derek. Brooklyn tells Owen about the spy novel she found in Paris and Owen begs them to let him display the book as part of the shop's first anniversary celebration. Brooklyn is hesitant-she's shocked to find that the book is valuable!-so before agreeing, Derek checks out Owen's security system and finds it acceptable.
Derek is dismayed when he receives a mysterious letter from Paris announcing the death of Ned. Then late one night, someone is killed inside the spy shop. Is the writer's murder connected to Brooklyn's valuable book? Is there something even more sinister afoot? The police are called in, but Owen begs Derek to look into it as well. Little do Brooklyn and Derek realize how deeply they will have to delve into Derek's past in order to unmask an enemy who's been waiting for the chance to destroy everything they hold dear.
