First published in June 1926, 'The Murder of Roger Ackroyd' is voted by the British Crime Writers' Association as the "Best Crime Novel of all Time" by Agatha Christie, an English writer known for her 66 detective novels and 14 short story collections, particularly those revolving around fictional detectives Hercule Poirot and Miss Marple.

It is Agatha Christie's most daring crime mystery. An early and particularly brilliant outing of Hercule Poirot with its legendary twist changed the detective fiction genre forever. Roger Ackroyd knew too much. He knew that the woman he loved had poisoned her brutal first husband. He suspected also that someone had been blackmailing her. Now, tragically, came the news that she had taken her own life from a drug overdose. But the evening post brought Roger one last fatal scrap of information. Unfortunately, before he could finish the letter, he was stabbed to death.
