It was 1921 when Lord Peter Wimsey first encountered the Attenbury emeralds. The recovery of the magnificent gem in Lord Attenbury's most dazzling heirloom made headlines - and launched a shell-shocked young aristocrat on his career as a detective.
Now it is 1951 and Lord Peter has just shared the secrets of that mystery with his wife, detective writer Harriet Vane. Then the new young Lord Attenbury - grandson of Lord Peter's first client - seeks his help again, this time to help prove that he owns the gigantic emerald that Wimsey last saw in 1921.
It will be the most intricate and challenging mystery he has ever faced.
