Das fehlende Glied in der Kette

Hip Hip Hercule! A hundred years ago, the world's most famous detective solved his first case. Who poisoned the wealthy Mrs. Emily Inglethorp at her estate, Styles Court? Was it her husband Alfred, who seems to have his eyes on her inheritance? But her stepsons or the temperamental housekeeper could also be the murderers. In his first case, Hercule Poirot thoroughly examines all the residents of Styles until he finds the missing link in the chain. Agatha Christie's debut novel was the result of a bet: the author, who had never written a single book before, would not be able to craft a detective story where the reader simply cannot figure out the murderer, even though they receive the same clues as the investigator. Well, can you solve the mystery before Poirot does?.
