“I know what the world has done to my brother and how narrowly he has survived it. And I know, which is much worse, and this is the crime of which I accuse my country and my countrymen, and for which neither I nor time nor history will ever forgive them, that they have destroyed and are destroying hundreds of thousands of lives and do not know it and do not want to know it. One can be, indeed one must strive to become, tough and philosophical concerning destruction and death, for this is what most of mankind has been best at since we have heard of man. (But remember: most of mankind is not all of mankind.) But it is not permissible that the authors of devastation should also be innocent. It is the innocence which constitutes the crime.”

“There are no crimes and no criminals in these days. What is the use of having brains in our profession? I know well that I have it in me to make my name famous. No man lives or has ever lived who has brought the same amount of study and of natural talent to the detection of crime which I have done. And what is the result? There is no crime to detect, or, at most, some bungling villainy with a motive so transparent that even a Scotland Yard official can see through it.”

“They say that rape is the only crime in which the victim has to prove her innocence. And I want you to know, I believe in your innocence. You don’t have to prove anything to me.”

“The great question which, in all ages, has disturbed mankind, and brought on them the greatest part of their mischiefs ... has been, not whether be power in the world, nor whence it came, but who should have it.”

“I ask you neither for health nor for sickness, for life nor for death; but that you may dispose of my health and my sickness, my life and my death, for your glory ... You alone know what is expedient for me; you are the sovereign master, do with me according to your will. Give to me, or take away from me, only conform my will to yours. I know but one thing, Lord, that it is good to follow you, and bad to offend you. Apart from that, I know not what is good or bad in anything. I know not which is most profitable to me, health or sickness, wealth or poverty, nor anything else in the world. That discernment is beyond the power of men or angels, and is hidden among the secrets of your providence, which I adore, but do not seek to fathom.”

“Your colleague, Captain Grimes, has been convicted before me on evidence that leaves no possibility of his innocence - of a crime (I might almost call it a course of action) which I can neither understand nor excuse. I dare say I need not particularise.”
