A brand new bumper omnibus gathering together over 50 classic Agatha Christie stories featuring Tommy and Tuppence Beresford, Harley Quin, Parker Pyne and Hercule Poirot, plus her rare Christmas Stories not available in any other volume. This new compendium of over 50 stories is the first time all the stories featuring Agatha Christie's detectives have been collected together. Here you will meet - Parker Pyne - a consulting detective whose practice is to solve less murderous enigmas and restore happiness to his clients; Harley Quin - a tall, dark, mysterious young man who takes a more surreptitious approach to solving crime; Tommy and Tuppence Beresford - a newly married pair of self-styled 'Young Adventurers' who are prepared to do anything in the name of justice. And in addition to presenting the complete oeuvre for these detectives, this volume includes as a bonus four rare short stories featuring that grand master of detection, Monsieur Hercule Poirot, plus Agatha Christie's little-known Christmas stories written for children, including "Star Over Bethlehem" and "The Naughty Donkey".
