Reading my case yesterday, as the officers of the court question the mother-in-law of the suspected poisoner:
Q: Is there any rumor as to who it was who tried to poison your son?
A: Yes: everybody says it was his wife.
Q: And do they say why she might have tried to poison him?
A: Because she wanted him to die.
(I like to imagine the last delivered in an incredulous, "well, duh!" voice. I also like to imagine the rolling of the eyes as the inquisitor followed up with "Well, why did she want him to die?")
