Secret Service was a 32-page weekly magazine of detective stories featuring Old and Young King Brady, a world-renowned team of United States Secret Service agents. The pair run the Brady Detective Bureau in New York City and, with the help of Alice, their able office assistant, they track down criminals across the globe. Wall Street swindles and opium rings based in Chinatown are principal plot devices. Miscellaneous material at the back of later issues included a current events column, short stories, and numerous advertisements. Cover illustrations sometimes recorded current events (e.g., the 1906 San Francisco fire and earthquake), as well as notable markers of contemporary society, such as the Statue of Liberty and the New York subway. The series was published from 1899 through 1925.
