The sound that attracted my attention was a low, grinding rasping that seemed to come from the floor of the cell above, which was the roof of my cell. One person above walked back and forth with his shoes on, making considerable noise. Something very unusual. The rasping became more distinct, and after an hour’s thought I concluded that somebody up above was boring a hole through the thin steel floor and that the walking was to cover the noise of drilling and to keep watch for the guard. Before nine o’clock there was an inch hole in the floor, and strips of tender meat, long pieces of bread, toasted to hold them together, cigarettes, and matches were being lowered into my cell. After them came a long, thin piece of rubber hose, from which I sucked about a quart of strong coffee.
