The Wolfe Widow (A Book Collector Mystery);

As Thanksgiving approaches, Jordan Bingham is grateful for her job researching rare books for Vera Van Alst, the infamous curmudgeon of Harrison Falls, New York. But when an uninvited guest makes an appearance, much more than dinner is disrupted—and Jordan is thankful just to be alive…
 
Vera Van Alst doesn’t normally receive visitors without appointment, but she agrees to see the imperious Muriel Delgado upon arrival. Shortly thereafter, Jordan is told that her position is being terminated. Evicted from the Van Alst House, Jordan is determined to find out what hold Muriel has over her erstwhile employer.
 
It seems Muriel has designs on Vera’s money and property—not to mention a particular interest in her collection of Nero Wolfe first editions. When Jordan discovers a deadly connection between Muriel and the Van Alst family, it’s up to her to put the house in order and stop a killer from going back to press.
