I did not care for Anthony Horowitz's best selling Magpie Murders but I feel that anyone interested in writing and publishing should read it because, aside from the stories it tells, it includes a wealth of information about publishing, mysteries, and the writing life.
Horowitz has (at this writing) written over 40 books including the teen spy series Alex Rider, which he adapted into a movie. The Conan Doyle estate commissioned him to write two new Sherlock Holmes mysteries, Moriarty and The House of Silk, both bestsellers. The Ian Fleming estate commissioned him to write the James Bond novel Trigger Mortis. As a television screenwriter he created and wrote Midsomer Murders and Foyle's War.
Alan Conway's "Magpie Murders," ostensibly the ninth in the August Pünd series, is in the style of Agatha Christie set in a 1955 English village complete with a brilliant, if opaque, private investigator; his faithful, much younger, sidekick; a helpful, if dim, police inspector; two murders, and a half dozen suspects with reasons to kill. That is, everyone but the actual killer which Pünd has to finally expose.
I did not care for either "Conway's" mystery nor the mystery in which it is embedded because they are both puzzle boxes with red herrings, lucky (or unlucky) coincidences, and—for me—unconvincing murderers. Interestingly, we learn that Conway himself did not care for the character and the series that had made him wealthy, and one of the book's many pleasures is learning the connections between Conway's life and his book.
I am in awe of Anthony Horowitz's ability to write in the style of Agatha Christie, Dorothy Sayers, and others of the period. Here is "Conway's" third-person, omniscient POV introduction to Pünd:
"Dr. Benson examined his patient with a certain amount of puzzlement. The name Atticus Pünd was familiar to him, of course. He was often mentioned in the newspapers—a German refugee who had managed to survive the war after spending a year in one of Hitler's concentration camps. At the time of his arrest he had been a policeman working in Berlin—or perhaps it was Vienna—and after arriving in England he had set himself up as a private detective, helping the police on numerous occasions. He did not look like a detective. He was a small man, very neat, his hands folded in front of him. He was wearing a dark suit, a white shirt and a narrow black tie. His shoes were polished. If he had not known otherwise, the doctor might have mistaken him for an accountant, the sort who would work for a family firm and who would be utterly reliable. And yet there was something else . . ."
By contrast, here is Susan Ryeland's first person POV description of Alan Conway:
"I didn't like him. I'm sorry to say it but he just struck me as a bit of a cold fish. You'll have seen photographs of him on the book jackets, the slim face, the closely cropped silver hair, the round wire-framed glasses. On television or on the radio he'd always had a sort of eloquence, an easy charm. He was nothing like that then. He was puffy and a little overweight, wearing a suit with chalk marks on the sleeves. His manner was at once aggressive and eager to please. He wasted no time telling me how much he wanted to be a published author but he showed almost no enthusiasm now that the moment had come. I couldn't work him out . . ."
And here is a sample from the thankfully brief excerpt of the kind of book Conway would like the be known for:
"Lord Quentin Crump comes slumping down the staircase, lording it as he always does over the cooks and maids, the under-butlers and the footmen that exist only in his anfractuous imagination, that have in truth slipped hugger-mugger into the adumbration of family history. They were there when he was a boy and in some ways he is still a boy, or perhaps it is more true to say that the boy he was lurks obstinately in the fleshy folds that fifty years of unhealthy living have deposited on the barren winter tree that is his skeleton . . ."
I believe any aspiring mystery writer could study Magpie Murders to understand how a consummate professional describes character and place, drops clues, and propels the story forward, in this case both stories. While puzzle box mysteries are not to my taste (I agree with Edmond Wilson; who cares who killed Roger Ackroyd?), I learned a great deal from the book that I plan to use in my own writing.
