Arthur B. Reeve (1880-1936) was an American author and professor of English. He is best known for his series of detective stories featuring the scientific detective Craig Kennedy, which were popular during the early 20th century. Reeve was also a prolific screenwriter and worked on several film adaptations of his own work. John W. Grey (1875-1956) was an American author and screenwriter. He was a longtime collaborator with Reeve and together they wrote several books and screenplays, including ""The Master Mystery"" and ""The Exploits of Elaine."" Grey also worked as a newspaper reporter and served as an editor for various magazines. Reeve and Grey's partnership began in the early 1910s, when they collaborated on several short stories featuring Craig Kennedy. Their work was well received and led to the creation of a successful series of novels and films. They continued to work together throughout the 1920s and 1930s, producing dozens of books and screenplays. Despite their success, Reeve and Grey's work fell out of favor in the years following their deaths. However, their influence can still be seen in the detective and mystery genres today.
