Убийство Роджера Экройда
Around this time, a novel was offered for publication to The Bodley Head and was rejected. No other information exists on this novel, but Zemboy suggests it was "The Big Four". His theory continues with Christie's relationship to her new publisher William Collins, Sons. Christie would have realized that "The Big Four" was an inferior novel and went to work writing "The Murder of Roger Ackroyd" for the new publisher.
