Billy Prothero was a sturdy sort of boy, generously wanting in good looks. His hair was rough, and his complexion muddy, and he walked about with his hands in his pockets, long flexible lips protruded in a whistle, and a rather shapeless nose well up to show he didn't care. Providence had sought to console him by giving him a keen eye for the absurdity of other people. He had a suggestive tongue, and he professed and practised cowardice to the scandal of all his acquaintances. He was said never to wash behind his ears, but this report wronged him. There had been a time when he did not do so, but his mother had won him to a promise, and now that operation was often the sum of his simple hasty toilet. His desire to associate himself with Benham was so strong that it triumphed over a defensive reserve. It enabled him to detect accessible moments, do inobtrusive friendly services, and above all amuse his quarry. He not only amused Benham, he stimulated him. They came to do quite a number of things together. In the language of schoolboy stories they became “inseparables.” Prothero's first desire, so soon as they were on a footing that enabled him to formulate desires, was to know exactly what Benham thought he was up to in crossing a field with a bull in it instead of going round, and by the time he began to understand that, he had conceived an affection for him that was to last a lifetime. “I wasn't going to be bullied by a beast,” said Benham. “Suppose it had been an elephant?” Prothero cried.... “A mad elephant?... A pack of wolves?” Benham was too honest not to see that he was entangled. “Well, suppose in YOUR case it had been a wild cat?... A fierce mastiff?... A mastiff?... A terrier?... A lap dog?” “Yes, but my case is that there are limits.” Benham was impatient at the idea of limits. With a faintly malicious pleasure Prothero lugged him back to that idea. “We both admit there are limits,” Prothero concluded. “But between the absolutely impossible and the altogether possible there's the region of risk. You think a man ought to take that risk--” He reflected. “I think--no--I think NOT.” “If he feels afraid,” cried Benham, seeing his one point. “If he feels afraid. Then he ought to take it....” After a digestive interval, Prothero asked, “WHY? Why should he?”
