Les sept cadrans & Le crime est notre affaire

The Seven Dials Mystery is a work of detective fiction by Agatha Christie, first published in the UK by William Collins & Sons on 24 January 1929 and in the US by Dodd, Mead and Company later in the same year.In this novel, Christie brings back the characters from an earlier novel, The Secret of Chimneys: Lady Eileen (Bundle) Brent, Lord Caterham, Bill Eversleigh, George Lomax, Tredwell, and Superintendent Battle. The novel received mostly unfavourable reviews. One reviewer noted a change in style ("Less good in point of style") but felt the novel "maintains the author's reputation of ingenuity." Another was quite disappointed in the change in style from some of her earlier novels, saying that she had "deserted the methodical procedure of inquiry into a single and circumscribed crime for the romance of universal conspiracy and international rogues." Another felt that the story started out well, but then earned sharp criticism for the author as "she has carefully avoided leaving any clues pointing to the real criminal. Worst of all, the solution itself is utterly preposterous." In 1990, this novel was considered to have the same characters and house parties as The Secret of Chimneys "but without the same verve and cheek."
