Ask a Policeman. Агата Кристи

      FOREWORD

      ASK A DETECTIVE WRITER

      By MARTIN EDWARDS

      ASK A POLICEMAN, first published in 1933, was the fourth in a sequence of collaborative mysteries produced in quick succession by members of the Detection Club. The Club was set up three years before this book was written, as an elite and rather secretive social network of leading detective novelists. It continues to flourish to this day, although current members include prominent thriller and espionage writers as well as specialists in the whodunit.

      Ask a Policeman followed two radio serials, Behind the Screen and The Scoop, and a full-length detective novel, The Floating Admiral. These collective ventures generated enough revenue for the Club to rent premises in Soho, where, as Dorothy L. Sayers put it, members convened “chiefly for the purpose of eating dinners together and of talking illimitable shop.”

      In the early Thirties, detective fiction was hugely popular, and many writers treated the detective story as a game in which they pitted their wits against their readers’. It was supposed to be important to “play fair”. Father Ronald Knox, a founder member of the Club, went so far as to devise a jokey Decalogue of ten commandments for the genre (“not more than one secret room or passage is allowable”, for instance)—which he and his colleagues were happy to break whenever it suited them.

      Anthony Berkeley, who organized the dinner meetings that led to the foundation of the Club, and Dorothy L. Sayers, a towering presence in its ranks, headed a group of talented crime writers who became increasingly determined to explore criminal psychology and write novels of literary merit. Yet they too relished the intellectual exercise of creating elaborate puzzles.

      Writing a round-robin mystery presents a variety of challenges for any team of authors, and Club members had to decide how to top the success of The Floating Admiral. Their answer was to come up with a fresh concept—they would write a story in which they exchanged detectives with each other. This gimmick afforded contributors the chance to poke fun at the genre, and at the quirks of their colleagues’ most famous sleuths. But transforming the idea into a readable story was bound to prove complex, with each contributor in turn needing plenty of space to develop the narrative in a distinctive way. This explains why, although 13 members provided ingredients for the mix in The Floating Admiral, just half a dozen created Ask a Policeman.

      The original dust jacket blurb captured the gleeful spirit of the enterprise:

      “Here is something delightfully new in ‘thrills’—a story which combines the interest of detection with the fun of parody. A problem is propounded; ingenious, and, for the solvers, malicious, and in itself a parody of a thousand and one detective stories. A great newspaper proprietor dies in his study, and suspicion falls upon an Archbishop, a Secretary, a Police Commissioner, and the Chief Whip of the political party in power. There is, too, a Mysterious Lady. What, then, can the Home Secretary do but call in the Amateur Experts? There are four of them; each takes
