“Mysteries force a man to think, and so injure his health.”

“It is impossible to say how first the idea entered my brain; but once conceived, it haunted me day and night. Object there was none. Passion there was none. I loved the old man. He had never wronged me. He had never given me insult. For his gold I had no desire. I think it was his eye! yes, it was this! He had the eye of a vulture –a pale blue eye, with a film over it. Whenever it fell upon me, my blood ran cold; and so by degrees – very gradually –I made up my mind to take the life of the old man, and thus rid myself of the eye forever.”

“I wish I could write as mysterious as a cat.”

“Let my heart be still a moment and this mystery explore...”

“Man's real life is happy, chiefly because he is ever expecting that it soon will be so.”

“No thinking being lives who, at some luminous point of his life of thought, has not felt himself lost amid the surges of futile efforts at understanding, or believing, that anything exists greater than his own soul.”

“..bear in mind that, in general, it is the object of our newspapers rather to create a sensation-to make a point-than to further the cause of truth." Dupin in "The Mystery of Marie Roget”
