Before he entered the small screen courtroom as Perry Mason, Raymond Burr was a big screen heavy and a busy radio actor. He played everything from killers to cops to cavalrymen, and he supported stars in their visits to "radio\'s outstanding theater of thrills." In the late 1950s, he moved from the supporting cast to the lead role on\\xa0Suspense, and we\'ll hear two old time radio thrillers that aired just months before he went on the air as Mason: "The Paralta Map" (originally aired on CBS on March 10, 1957) and "Murder on Mike" (originally aired on CBS on July 28, 1957).
