“He challenged the world with his genius, and the world defeated him by ignoring the challenge and starving him. He stopped writing because he had failed and because he had no choice but to accept the world’s terms: there is no mystery here. This was not insanity, but common sense.”

“In everything that can be called art there is a quality of redemption. It may be pure tragedy, if it is high tragedy, and it may be pity and irony, and it may be the raucous laughter of the strong man. But down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid.The detective in this kind of story must be such a man. He is the hero; he is everything. He must be a complete man and a common man and yet an unusual man. He must be, to use a rather weathered phrase, a man of honor -- by instinct, by inevitability, without thought of it, and certainly without saying it. He must be the best man in his world and a good enough man for any world. I do not care much about his private life; he is neither a eunuch nor a satyr; I think he might seduce a duchess and I am quite sure he would not spoil a virgin; if he is a man of honor in one thing, he is that in all things.He is a relatively poor man, or he would not be a detective at all. He is a common man or he could not go among common people. He has a sense of character, or he would not know his job. He will take no man's money dishonestly and no man's insolence without due and dispassionate revenge. He is a lonely man and his pride is that you will treat him as a proud man or be very sorry you ever saw him. He talks as the man of his age talks -- that is, with rude wit, a lively sense of the grotesque, a disgust for sham, and a contempt for pettiness.The story is the man's adventure in search of a hidden truth, and it would be no adventure if it did not happen to a man fit for adventure. He has a range of awareness that startles you, but it belongs to him by right, because it belongs to the world he lives in. If there were enough like him, the world would be a very safe place to live in, without becoming too dull to be worth living in.”

“Common sense is the guy who tells you that you ought to have had your brakes relined last week before you smashed a front end this week. Common sense is the Monday morning quarterback who could have won the ball game if he had been on the team. But he never is. He's high up in the stands with a flask on his hip. Common sense is the little man in a grey suit who never makes a mistake in addition. But it's always someone else's money he's adding up.”

“I had been stalking the bluebottle fly for five minutes, waiting for him to sit down. He didn't want to sit down. He just wanted to do wing-overs and sing the prologue to Pagliacci. I had the fly swatter poised in midair and I was all set. There was a patch of bright sunlight on the corner of the desk and I knew that sooner or later that was where he was going to light. But when he did, I didn't even see him at first. The buzzing stopped and there he was. And then the phone rang.”

“He ran as he'd never run before, with neither hope nor despair. He ran because the world was divided into opposites and his side had already been chosen for him, his only choice being whether or not to play his part with heart and courage. He ran because fate had placed him in a position of responsibility and he had accepted the burden. He ran because his self-respect required it. He ran because he loved his friends and this was the only thing he could do to end the madness that was killing and maiming them.”

“Well, the husband was very depressed for the longest while. Even after he found out that his wife was going to pull through, he was still very depressed. Not about the accident, though. I mean, the accident was one thing, but it wasn't everything. I'd get up to his mouth-hole, you know, and he'd say no, it wasn't the accident exactly but it was because he couldn't see her through his eye-holes. He said that was what was making him feel bad. Can you imagine? I'm telling you, the man's heart was breaking because he couldn't turn his goddamn head and see his goddamn wife.”
