104 Old King Brady stories were published between 1885 and 1894 written by Francis Worcester Doughty under the penname “A New York Detective.” After a five year hiatus, Old King Brady returned in 1899 forming the Brady Detective Bureau which reported directly to the United States Secret Service. Joining him was Harry Brady, known as Young King Brady—they had the same last name, but James and Harry were not related. Also with the Bureau was Alice Montgomery, a blond, attractive former operative for the Australian Secret Service.
Though they fought crimes throughout the United States and in exotic locations around the world, the Bradys spent much of their time on Mott Street in New York City, and in San Francisco’s Chinatown, fighting the “Yellow Peril.” Their enemies were most often Chinese highbinders, opium peddlers, and white slavers, with names like Hop Lee, Hi-Lo-Jak, and Joss House Jim.
After 726 more weekly adventures between 1899 and 1912 the Brady Detective Bureau closed up shop. “A New York Detective” had run out of plots and dime novels, in general, could not compete with moving pictures for the small change of American boys.
