"Yes! Sitting in his chair and lying half on the desk. He had been stabbed in the back."

"Was the window, or one of the windows, open?"

"I never noticed. And remember, Jadby did not say that the middle window was ajar, but only that the latch had been unfastened."

"I remember that. What happened next?"

Shepworth explained. "I found Sir Oliver dead, and Mona unconscious."
