Double Sin and other stories

A BLOOD-RED RUBY... A WASP'S NEST OF FEAR... A MANSION MADE FOR MURDER... confront that suave master sleuth, Hercule Poirot, and the inimitable Miss Jane Marple, as they match wits with as cunning and deadly a killing crew as Agatha Christie has ever assembled. In tales that range from the sinister streets of London to the terror-shadowed English countryside to a bizarre chamber of horror in Paris, you are invited on a journey into superlative reading pleasure.

WITH OVER 200 MILLION COPIES OF HER BOOKS SOLD, AGATHA CHRISTIE IS UNEQUALLED AS A RENOWED AND DISTINGUISHED AUTHOR OF INGENIOUS TALES OF MYSTERY AND SUSPENSE.
