The Murder of Roger Ackroyd
The title alludes to two of Agatha Christie's works: her breakthrough novel, "The Murder of Roger Ackroyd", and a character (Amy Murgatroyd) from a later tale, "A Murder is Announced". Furthermore, there are clear elements which highlight Christie's influence. There are many more references to prominent crime writers and their works, including, tongue-in-cheek, an anachronistic allusion to critic Edmund Wilson's 1945 essay, "Who Cares Who Killed Roger Ackroyd?".
