“But it is the mark of all movements, however well-intentioned, that their pioneers tend, by much lashing of themselves into excitement, to lose sight of the obvious.”

“Well, well -- the prizes all go to the women who 'play their cards well' -- but if they can only be won in that way, I would rather lose the game ... [C]lever [women] bide their time -- make themselves indispensable first, and then se font prier [=play hard to get]. Clever -- but I can't do it.”

“Nothing goes so well with a hot fire and buttered crumpets as a wet day without and a good dose of comfortable horrors within. The heavier the lashing of the rain and the ghastlier the details, the better the flavour seems to be.”

“I entirely agree that a historian ought to be precise in detail; but unless you take all the characters and circumstances into account, you are reckoning without the facts. The proportions and relations of things are just as much facts as the things themselves.”

“The two men sat silent for a little, and then Lord Peter said: "D'you like your job?" The detective considered the question, and replied: "Yes—yes, I do. I know it to be useful, and I am fitted to it. I do it quite well—not with inspiration, perhaps, but sufficiently well to take a pride in it. It is full of variety and it forces one to keep up to the mark and not get slack. And there's a future to it. Yes, I like it. Why?" "Oh, nothing," said Peter. "It's a hobby to me, you see. I took it up when the bottom of things was rather knocked out for me, because it was so damned exciting, and the worst of it is, I enjoy it—up to a point. If it was all on paper I'd enjoy every bit of it. I love the beginning of a job—when one doesn't know any of the people and it's just exciting and amusing. But if it comes to really running down a live person and getting him hanged, or even quodded, poor devil, there don't seem as if there was any excuse for me buttin' in, since I don't have to make my livin' by it. And I feel as if I oughtn't ever to find it amusin'. But I do.”

“Oh, well, faint heart never won so much as a scrap of paper”

“Well, it's no good jumping at conclusions.""Jump? You don't even crawl distantly within sight of a conclusion. I believe if you caught the cat with her head in the cream-jug you'd say it was conceivable that the jug was empty when she got there.”
