Author Patricia Wentworth (pseudoniem of Dora Amy Elles) penned this crime fiction novel in 1933. A very minor obstacle of the book is getting acquainted with the writing style of that era. I also thought it was interesting that the book's main character, Caroline Leigh, adamantly pursues a relationship with a cousin, Jim Randal. The story is entertaining to solve who stole the seven green emeralds and who shot Elmer Van Berg.
