The Attenbury Emeralds

  Thirty years after the fact Lord Peter Wimsey tells his wife the story of how he solved the disappearance and recovery of the Attenbury Emeralds in 1921 as he was recovering from the shock of World War I.  In the midst of the story  Lord Attenbury, grandson of the old Lord has come to Peter to ask for help proving that the Emerald in the Attenbury bank vault truly belongs to the family and not the mysterious stranger who is claiming it for their own.
