Absolute silence reigned, a silence that to an imaginative person like Rupert could be felt, almost seen. It seemed to be part of the stone corridors, the granite walls. And granite appeared to be beaten into the convicts' souls until the expression of it was graven on their faces. Like their walls they were cold, grey, silent. Here and there a few retained traces of humanity; others suggested primeval men of the stone age, though they wore no hair on their faces and their heads had been shaven until nothing but innumerable spikes stood erect from the scalp.

Each man bent over his work as if he were absorbed in it. Rupert, watching closely, noticed their eyes roved here and there, moving quickly, sometimes fearfully; like the eyes of an animal ever on the watch. Sometimes their lips moved, too, though not a sound escaped them.

They passed into the kitchens—here there was blessed warmth again and the smell of newly-baked bread—through innumerable corridors and passages.

They were shown into a cell, A.C. 2061. "Just room enough to die"—as Despard humorously expressed it.

The cells in which the majority of prisoners were confined were built in the middle of a square, the floors rising one above the other, all securely railed off, so that one warder on guard above, could command a view of every cell in the square.

Rupert felt a sense of relief when they reached the porter's lodge again. They had to wait a moment while a gang of convicts marched in through the courtyard. They were accompanied by warders with loaded carbines. They had been at work out on the moorlands, quarrying and farming and digging peat.

"Well, I hope you're satisfied," Rupert said, when they found themselves walking along the road towards Princetown. "I felt a beast all the time. I only wonder the poor brutes didn't get up and go for us."

"Oh, they're happy enough," Despard said carelessly. "But, I confess it's good to be outside again in the air and the sunshine, and, by gad! it has given me an appetite. I hope the local hotel can provide us with something to eat."

They met Marjorie just outside the market-place, and though all she wanted was a little bread and cheese and a glass of milk, Despard insisted on ordering a big luncheon and opening a bottle of champagne.

"We want something to take the taste of the granite out of our mouths," he laughed.
