Nina de Gramont’s The Christie Affairis the latest roster for Reese Witherspoon’s popular book club.

The actor and media expert made the Announcement on Instagram, writing, “True crime buffs…this book is for you!…I found myself reading this book in one sitting – I think you’ll really like this book.”

De Gramont’s novel, published Tuesday by St. Martin’s, is based on the true story of the 11-day disappearance of Agatha Christie in 1926; the mystery writer left the house after her husband told her he was planning a divorce. She was eventually found in a hotel in Yorkshire.

In a one-star review, a critic of Kirkus called the Gramont’s novel “devilishly clever, elegantly composed and structured—simply gorgeous.”

Late last year, Miramax optional the rights to the Gramont’s novel, with plans to adapt it into a limited series written by Juliette Towhidi.

“This story is all about murder and lies and love and discovery,” Witherspoon said. “I loved it so much. I couldn’t put it down. I read it in one sitting and I think you are going to love it.”

The Gramont responded to her book’s selection on Instagram, writing, “Best pub day gift ever! So excited to be Reese’s book club pick for February!
