Michael Dirda, The Washington Post’s longtime Pulitzer Prize-winning book reviewer, won an Edgar Award on Thursday night in New York for his critical biography, “On Conan Doyle: Or, The Whole Art of Storytelling.”

The awards, named after Edgar Allan Poe, are presented annually by the Mystery Writers of America to honor the best writing in mystery fiction, nonfiction and television.

Dirda’s book, published by Princeton University Press, describes the 63-year-old’s lifelong obsession with the creator of Sherlock Holmes, which began when Dirda, as a fifth-grader, read “The Hound of the Baskervilles.”

A review in The Post last year said, “Dirda intertwines his experiences as a young fan and now a member of the Baker Street Irregulars with an erudite tour of Conan Doyle’s life and other writings. He makes a compelling case for the value of the author’s supernatural, historical and science fiction — if not his treatises on spiritualism, which Conan Doyle valued more than his fiction.
