Skimpole protests to Bucket, 'What's this for? I don't understand it, it is of no use to me, take it away.' Bucket still entreats Skimpole to accept it. Are there reasons why Skimpole, not being warped by prejudices, should accept it? Yes. Skimpole perceives them. What are they? Skimpole reasons with himself, this is a tamed lynx, an active police-officer, an intelligent man, a person of a peculiarly directed energy and great subtlety both of conception and execution, who discovers our friends and enemies for us when they run away, recovers our property for us when we are robbed, avenges us comfortably when we are murdered. This active police-officer and intelligent man has acquired, in the exercise of his art, a strong faith in money; he finds it very useful to him, and he makes it very useful to society. Shall I shake that faith in Bucket because I want it myself; shall I deliberately blunt one of Bucket's weapons; shall I positively paralyse Bucket in his next detective operation?
