A elderly male gossip columnist is shot and killed in an apartment in which we find an old "friend" of "Ballinger," a hot babe called "Kathy" (played by the mid-20s film actress Janice Rule!). She's an actress in this role and she was afraid of this writer's nastiness and thought more might come of it, so she had a bought a gun. Unfortunately, that's the gun that killed the guy. Naturallly, she says she's innocent and since she's nice-looking, even though she does all the guilty things, he believes her. That's "Frank."
"Dolly" is a middle-aged hard-looking woman (Claire Carleton) who has been through a lot, you can see in her face and hear it in her voice and what she says. She, and about half of Chicago, it seems, had secrets that this gossip-monger knew and held secret in a safe at Dolly's Bar. Thus, the suspects were many. Nobody liked the guy who was killed.
Most of the "action" takes place in one room in this episode, which makes it kind of talky after awhile. It isn't one of the more fascinating episodes because too long is spent in one place: Dolly's room, which opens into a big one-way mirror to the floor show. It's a little bizarre, but wears thin after a short time.
The idea is for Frank to prove another woman innocent. He likes to do that sort of thing.
