A.J. Finn is an American author best known for his breakout debut, The Woman in the Window. The book was a massive hit upon the time of its release and has been translated into many languages. The book has also been made into a film. A.J. Finn is actually a pen name for the author, Dan Mallory.
Mallory was a long time book editor and worked in publishing for a decade. He mostly worked on mysteries and thrillers, with that being his chosen genre here. In addition to that, he wrote for numerous publications, including the Los Angeles Times, the Washington Post, and the Times Literary Supplement.
Mallory came under quite a bit of controversy as a series of lies he told were made public, but the book series will continue.
