Along with Agatha Christie and Dorothy L Sayers, Margery Allingham is ranked among one of the most distinguished and beloved detective fiction writers of the 'Golden Age'. Agatha Christie herself praised Margery Allingham, saying that out of all the detective stories she remembers, Margerty Allingham's 'stand out like a shining light'. Born in London in 1904, Margery published her first novel, Blackkerchief Dick, at the age of 19. The White Cottage Mystery was her first detective story, written as a serial for the Daily Express in 1927 and published as a book a year later.
