midnight
He remained in the park till it was closed and then began to walk about . He was very tired . The thought came to him that an accident would be a piece of luck , so that he could be taken to a hospital and lie there , in a clean bed , for weeks . At midnight he was so hungry that he could not go without food any more , so he went to a coffee stall at Hyde Park Corner and ate a couple of potatoes and had a cup of coffee . Then he walked again . He felt too restless to sleep , and he had a horrible dread of being moved on by the police . He noted that he was beginning to look upon the constable from quite a new angle .
