The Attenbury Emeralds

The recovery of the magnificent gem in Lord Attenbury's dazzling heirloom launched a shell-shocked young aristocrat on his career as a detective in 1921. Thirty years later, a happily married Lord Peter has just shared the secrets of that mystery with his wife, the detective novelist Harriet Vane. Suddenly, the new Lord Attenbury-grandson of Lord Peter's first client-seeks his help to prove who owns the emeralds. As Harriet and Peter contemplate the changes that the war has wrought on English society-and Peter, who always cherished the liberties of a younger son, faces the unwanted prospect of ending up the Duke of Denver after all.
