Lights, camera, action! This week, our old time radio sleuths are tackling cases connected with the movie business and finding mystery on and off screen. First, "the Lyon's Eye" has to protect a movie star from some unscripted violence. Frank Graham stars in "The Hollywood Story, or H is for the Many Things You Gave Me" from Jeff Regan, Investigator (originally aired on CBS on March 22, 1950). Next, Dick Powell goes west when the head of a movie studio is blackmailed - and later framed for murder - in "The Hollywood Story" from Richard Diamond, Private Detective (originally aired on CBS on August 23, 1953). Finally, a corpse in a seaside amusement park is connected to a silent movie star and the long-ago murder of her husband in "The Silent Queen Matter" - a five-part Johnny Dollar mystery starring Bob Bailey as "America's fabulous freelance insurance investigator" (originally aired on CBS between October 29 and November 2, 1956).
