The chinless man obeyed. His large pouchy cheeks were quivering uncontrollably. The door clanged open. As the young officer entered and stepped aside, there emerged from behind him a short stumpy guard with enormous arms and shoulders. He took his stand opposite the chinless man, and then, at a signal from the officer, let free a frightful blow, with all the weight of his body behind it, full in the chinless man’s mouth. The force of it seemed almost to knock him clear of the floor. His body was flung across the cell and fetched up against the base of the lavatory seat. For a moment he lay as though stunned, with dark blood oozing from his mouth and nose. A very faint whimpering or squeaking, which seemed unconscious, came out of him. Then he rolled over and raised himself unsteadily on hands and knees. Amid a stream of blood and saliva, the two halves of a dental plate fell out of his mouth.
