When Roger Ackroyd is found dead in his study the day after his fiancée?s unexpected suicide, the illustrious detective Hercule Poirot comes out of retirement to take on the complicated case. Only a handful of close friends and family saw Roger Ackroyd the day he died, but almost all have solid alibis and were seemingly nowhere near him at his time of death. But as Poirot?s investigation uncovers new details, the suspects? alibis begin to unravel, and nearly everyone reveals themselves to have ample motive and opportunity to be the culprit. Was it for his money? For revenge? For keeping dangerous secrets hidden? Only one of the untrustworthy parties can be the real killer, and it is up to Poirot to sort through every clue and red herring to find the truth of who killed Roger Ackroyd.
