“I was at Chez Pierre’s having lunch.
“You had lunch with your former husband?”
“No, I was having lunch with Katy Lawrence, a friend.”
“But your husband was there. Why?”
“The deadbeat wanted more spousal support. As if I wasn’t paying enough already!
“Did that make you angry?”
“Yes”
“Angry enough to kill him?”
“No.”
“He was dead an hour later. That makes you the last person to see him alive.”
“No, I wasn’t”
“Then who was?”
“The killer, of course.”
