Later, in the secret passageway, I had to bring Mrs. White up to date on what had happened to her during her interrogation of Professor Plum.
"I had his cock in my mouth?" Mrs. White asked, surprised and delighted.
"Yes," I said testily. "The whole damn thing."
"That's great," she said. "I always dream about sucking cock."
"Me too," I mumbled.
"I just wish I could remember it."
"Well," I said grumpily, "I'll remember it for you."
"Thanks," she said. "You don't think Professor Plum is responsible for the murder?"
"No," I said. "If Mr. Boddy was sending him videotapes of you masturbating and Ms. Scarlet getting pronged up the ass, he wouldn't do anything that would stop the flow of free pornography." She looked unconvinced. "Trust me," I told her. "Pornography is very expensive these days."
"So what's next?" Mrs. White asked.
"I want you to continue interviewing suspects," I told her. "And here's a tipβ¦asking questions is easier when your mouth is free of obstructions."
"I'll try to keep that in mind," she assured me testily.
"Lead the way," I told her.
I followed as she led me up some creaky stairs. I could hear faint voices ahead of us.
"That sounds like Colonel Mustard," I whispered, recognizing the deep, husky voice.
"We're approaching the conservatory," Mrs. White whispered back.
She knelt down by a narrow, waist-high shaft that branched off the main passageway. "If we crawl down here, we'll be able to see him from an air duct that overlooks the greenhouse."
I examined the crawlspace. "Can we both fit in there?" I asked.
"It'll be a tight fit," she admitted, "but we can do it."
