The Perry Mason character was inspired by
Earl Rogers, a trial attorney who appeared in 77 murder trials but lost only three. He was recognized for the extensive use of demonstratives, e.g., visuals, charts and diagrams, during trial before it became common practice. Rogers is famous for his defense of, and attorney-client disagreement with,
Clarence Darrow, a fellow attorney who was charged with attempted jury bribery in 1912. While the Perry Mason novels seldom delved deeply into characters' lives, the novels were rich in plot detail which was reality-based and drawn from his own experience. In his early years writing for the pulp magazine market, Gardner set himself a quota of 1,200,000 words a year. Much of the first Perry Mason novel,
The Case of the Velvet Claws, published in 1933, is set at the historic
Pierpont Inn near Gardner's old law office in Ventura, California. Gardner made an uncredited appearance as a judge in "The Case of the Final Fade-Out" (1966), the last episode of the series. ==Gardner's other works==
