“He said just as far as the edge of the rug, which was some eleven inches.” He continued without waiting for Juster to ask. “Which meant it would have been at an awkward angle for the light either from the window or the gas bracket, and too close to the wall to be comfortable. It blocked off access to a considerable part of the bookshelves, where books on travel and art were kept, books the butler assured me Mr. Fetters referred to often.” He was looking directly at Juster. “I concluded it was not where the chair was normally kept, and I looked at the rug to see if there were indentations from the feet. There were.” He took a deep breath. “There were also faint scuff marks on the pile and when I looked again at Mr. Fetters’s shoes, I found a piece of fluff caught in a crack in the heel. It seemed to have come from the rug.”

This time there was a murmur from the court. Reginald Gleave’s lips tightened, but it looked more like anger and resolution than fear.

Again Pitt went on without being asked. “Dr. Ibbs had told me he assumed Mr. Fetters leaned too far, overbalanced, and fell off the steps, cracking his head against the shelves on the corner. The force of the blow, with his body weight behind it, not only caused bruising severe enough for him to lose consciousness, but broke his neck, and this was the cause of his death. I considered the possibility that he had been struck a blow which had rendered him insensible, and then the room had been arranged to look as if he had fallen.” There was a sharp rustling in the front row, a hiss of indrawn breath. A woman gasped.

One of the jurors frowned and leaned forward.

Pitt continued without change of expression, but he could feel the tension mounting inside him, his palms sweaty.

“Books he would be likely to read had been pulled out and dropped. The empty spaces left by them had been filled from the top shelf, to explain his use of the ladder. The chair had been pushed close to the corner, and his body placed half concealed by it.”
