Daniel Mallory, better known by his pseudonym A. J. Finn, is an American novelist renowned for his work in the genre of crime fiction and psychological thrillers. Finn's writing career soared with the success of his debut novel, The Woman in the Window, which was released in 2018. The novel garnered widespread acclaim, climbing to the number one spot on the New York Times Best Seller list.

Finn's educational background is impressive, having earned a B.A. from Duke University and an M.Phil. from Oxford University. His work has not only captivated readers but also the film industry, leading to the adaptation of The Woman in the Window into a feature film directed by Joe Wright starring Amy Adams, Julianne Moore, and Gary Oldman.
