"More or less," she said. "Roger and I have been separated for about eighteen months. I'll tell you, the last few years have been hellish, to say the least. My marriage fell apart, my father had a heart attack, and then Mother died. After that, Daddy's health problems only got worse. Lorna house-sat for me when I needed to get away."

"You met her through your husband?"

"Yes. She worked for Roger for a little over three years, so I'd run into her if I popped in at the plant. I'd see her at the employee picnics in the summer and the annual Christmas party. I thought she was fascinating. Clearly a lot smarter than the job required."

"The two of you got along?"

"We got along fine."

I paused, wondering how to phrase the question that occurred to me. "If it's not too personal, can you tell me about your divorce?"

"My divorce?" she said.

"Who filed? Was it you or your husband?"

She cocked her head. "That's a curious question. What makes you ask?"

"I was wondering if your separation from Roger had anything to do with Lorna."

Serena's laugh was quick and startled. "Oh, good heavens. Not at all," she said. "We'd been married ten years, and we both got bored. He was the one who broached the subject, but he certainly didn't get any grief from me. I understood where he was coming from. He feels he has a dead-end job. He likes what he does, but he's never going to get rich. He's one of those guys whose life hasn't quite come up to his expectations. He pictured himself retired by the age of fifty. Now he's past that, and he still hasn't got a dime. On the other hand, I not only have a career I'm passionate about, but I'll have family money coming to me one of these days. Living with that got to be too much for him. We're still on friendly terms, we're just not intimate, which you're welcome to verify with him."

"I'll take your word for it," I said, though of course I'd check. "What about the house-sitting? How'd Lorna end up doing that?"

"I don't remember exactly. I probably mentioned in passing that I needed someone. Her place was small and remarkably crude. I thought she'd enjoy spending time in a more comfortable setting."

"How often did she sit?"

"Five or six times altogether, I'd guess. She hadn't done it for a while, but Roger thought she was still willing. I could check my calendar at home if it seems relevant."

"At the moment I don't know what's relevant and what's not. Were you satisfied with the job she did?"
