The Labours of Hercules

First published in book form in 1947, The Labours of Hercules comprises an even dozen mysteries starring Christie's most popular sleuth, the ever-dignified Hercule Poirot. The introductory chapter of the collection sets up the rest of the book. At a dinner party, another guest compares the labors of Poirot to those of Hercules, and the little Belgian is not amused. He has already decided to retire, but makes up his mind to take on 12 great cases - each somehow reflecting the labors accomplished by Hercules - as a farewell to crime solving. All of the cases are quite different from each other, from searching for a lost poet to hunting down a particularly ferocious murderer, from solving mysterious deaths of religious cult members to saving a young would-be politician from potential blackmailers.
