The original story written by Marland was Darryl was the killer of Carolyn and did it for the money and to have full control of the company. Midway Marland changed it because he felt it was a repeat of the Douglas story and he didn't want Frannie duped by another man who turned out to be a killer again. So he had one of Darryl lame assistant frame him for murder because he wanted the money and felt Darryl didn't love Carolyn and he did. The revelation still did well either ranking #2 or #3 for the week among the 11 soaps on the air at the time. IMO Marland made a mistake in changing the ending of the story.
