Curse of the Black Widow

[speaking as Valerie]

Laura Lockwood:
You can fool Laura, Olga dear... but not me.

[Detective Higbie and Flaps have found the body of Mrs. Lockwood]

Mark Higbie:
I thought she was dead...

Flaps:
She is now.

[Higbie is calling Flaps to get the results of a toxicology report on the blood of a victim]

Flaps:
I got the analysis back from my friend at USC. He doesn't know what it is, exactly.

Mark Higbie:
Well, what do you mean "exactly"?

Flaps:
He says the closest that it comes to is, er... All right, get this, you ready? The venom of a black widow spider.

[Silence]

Flaps:
You're not laughing.

Mark Higbie:
[Seriously] I know. [He hangs up thoughtfully]
