“Hammett was the ace performer... He is said to have lacked heart; yet the story he himself thought the most of [The Glass Key] is the record of a man's devotion to a friend. He was spare, frugal, hard-boiled, but he did over and over again what only the best writers can ever do at all. He wrote scenes that seemed never to have been written before.”

“down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid. 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. “He will take no man’s money dishonestly and no man’s insolence without a 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. “The story is this 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. 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.”

“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.”

“That's the difference between a champ and a knife thrower. The champ may have lost his stuff temporarily or permanently, he can't be sure. But when he can no longer throw the high hard one, he throws his heart instead. He throws something. He doesn't just walk off the mound and weep.”

“Mostly I just kill time," he said, "and it dies hard.”

“The main hallway of the Sternwood place was two stories high. Over the entrance doors, which would have let in a troop of Indian elephants, there was a broad stained-glass panel showing a knight in dark armor rescuing a lady who was tied to a tree and didn’t have any clothes on but some very long and convenient hair. The knight had pushed the vizor of his helmet back to be sociable, and he was fiddling with the knots on the ropes that tied the lady to the tree and not getting anywhere. I stood there and thought that if I lived in the house, I would sooner or later have to climb up there and help him. He didn’t seem to be really trying.”

“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.”
