Dime Detective Magazine #13

Frederick Nebel was born on November 3, 1903. He was a charter member of the Black Mask school, a group of writers who worked for the magazine and championed the hardboiled detective noir style of the 1920s. While most of Nebel's published work was short stories, he also authored three novels, Sleeper's East, Fifty Roads to Town, and But Not the End. He died in Laguna Beach, California, in 1967.

Erle Stanley Gardner (1889–1970) was a prolific American author best known for his works centered on the lawyer-detective Perry Mason. At the time of his death in March of 1970, in Ventura, California, Gardner was “the most widely read of all American writers” and “the most widely translated author in the world,” according to social historian Russell Nye. The first Perry Mason novel, The Case of The Velvet Claws, published in 1933, had sold twenty-eight million copies in its first fifteen years. In the mid-1950s, the Perry Mason novels were selling at the rate of twenty thousand copies a day. There have been six motion pictures based on his work and the hugely popular Perry Mason television series starring Raymond Burr, which aired for nine years and 271 episodes.
