The Seven Dedications of Agatha Christie

According to my calculations, there are 11 novels that have no dedications. This is an area where it's hard to speak with absolute certainty because different editions can go missing or disappear in subsequent editions. So here goes these eleven full length Agatha Christie novels that do not feature a dedication. The big four: Mystery cards on the table and 1945 Mideast Dials at 450 dock hickory house.
