A Dimension of Death — William Leisner

August, 1963: Rod Serling is hard at work preparing for the fifth (and ultimately final) season of his television series, Twilight Zone. But production is brought to a halt when a studio employee is found mysteriously murdered on show's soundstage. When it turns out Serling was one of the last people to see the young woman alive, the shadow of suspicion falls squarely on him. Now, in order to clear his name, he must find out for himself what happened, with the help of a former Los Angeles police officer turned television writer named Gene Roddenberry.
