Martha Brewster: [about the men they have poisoned] Let me see, now. This is eleven, isn't it, Abby?
Abby Brewster: Oh, no, dear. This makes twelve.
Martha Brewster: Abby, dear. I think you're wrong. This one is only eleven.
Abby Brewster: No, dear, because I remember when Mr. Hoskins first came in, it occurred to me that he'd make just an even dozen.
Martha Brewster: But, Abby, dear. I really don't think you should count the first one.
Abby Brewster: Oh, I was counting the first one, and that makes it twelve.
Martha Brewster: It does? Well, she's probably right. Abby usually is. I get them mixed up sometimes.
Mortimer Brewster: Makes it twelve? Twelve.
