Quote context

- Funny. In the past three years 12 women have disappeared from these different cities.

- In many circumstances, the history of each case is similar to this one.

- In what way?

- All these women are middle-aged with a small income or a little property.

- From what I can see, nearly all of them married the same type of man.

- You mean he's the husband of all these women?

- According to these dates, he must've been married to a half dozen at the same time.

- That's it. He's the proverbial sailor, but in his case it's a wife in every port.

- What's his racket?

- I don't know yet.

- Insurance?

- No, he's too smart for that.

- But not one of these women has shown up, and I doubt they ever will.
