And when someone turns up dead, Hamlet smells something rotten in Brooklyn… As the owner of Pettistone’s Fine Books, Darla is settling nicely into her new life, even reaching an uneasy truce with Hamlet.

And Hamlet can’t seem to stay out of trouble. One of the bookstore’s regular customers, a man who is renovating a local brownstone, claims he’s seen Hamlet prowling the neighborhood. When the man’s business partner is found dead, Darla discovers that Hamlet may have been the only witness to what could be murder. With the crafty cat’s help, she wonders if they just might be able to pounce on a killer...
