The Attenbury Emeralds — Jill Paton Walsh

In 1936, Dorothy L. Sayers abandoned the last Lord Peter Wimsey detective story. Sixty years later, a brown paper parcel containing a copy of the manuscript was discovered in her agent's safe in London, and award-winning novelist Jill Paton Walsh was commissioned to complete it. The result of the pairing of Dorothy L. Sayers with Walsh was the international bestseller Thrones, Dominations.

Now, following A Presumption of Death, set during World War II, comes a new Sayers-inspired mystery featuring Lord Peter Wimsey, revisiting his very first case. . . . It was 1921 when Lord Peter Wimsey first encountered the Attenbury Emeralds. The recovery of the gems in Lord Attenbury's dazzling heirloom collection made headlines -- and launched a shell-shocked young aristocrat on his career as a detective.

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 -- Jill Paton Walsh brings us a masterful new chapter in the annals of one of the greatest detectives of all time.
