Context

“Raskolnikov seemed offended. “Clear? Why don’t you catch him then?” he cried, maliciously gibing at Zametov. “Well, they will catch him.” “Who? You? Do you suppose you could catch him? You’ve a tough job! A great point for you is whether a man is spending money or not. If he had no money and suddenly begins spending, he must be the man. So that any child can mislead you.” “The fact is they always do that, though,” answered Zametov. “A man will commit a clever murder at the risk of his life and then at once he goes drinking in a tavern.” source
