Crime novelist Martin Edwards recommends ten Golden Age mystery authors he believes should be more widely known than they are. Henry Wade, Elisabeth Sanxay Holding, and C. Daly King are his top three.

Our top three begins with another American, a psychiatrist whose extraordinarily convoluted puzzles are at times maddening, but occasionally breathtaking. The Curious Mr Tarrant is a famous collection of short stories, but his three ‘obelist’ novels, each with an elaborate ‘cluefinder’ at the end, highlighting the clues in the text, fascinate me most. Obelists Fly High is a book I’ve always enjoyed—so much so that I pay tribute to it in a couple of different ways in my own latest novel, Mortmain Hall, a novel which revives the concept of the ‘cluefinder’.
