“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.”

“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.”

“...if you wish to tell me what crime I have committed, explain to me in what a crime consists. For as my conscience does not accuse me, I aver that I am not a criminal.”

“We are often criminals in the eyes of the earth, not only for having committed crimes, but because we know what crimes have been committed. - The Man in the Iron Mask (155)”

“We are living in the era of premeditation and the perfect crime. Our criminals are no longer helpless children who could plead love as their excuse. On the contrary, they are adults and the have the perfect alibi: philosophy, which can be used for any purpose - even for transforming murderers into judges.”

“Tell him next, that crimes cause their own detection. There's another bit of copy-book morality for you, Fosco. Crimes cause their own detection. What infernal humbug!”
