Wilkie Collins said this quote

Nothing in this world is hidden forever. The gold which has lain for centuries unsuspected in the ground, reveals itself one day on the surface. Sand turns traitor, and betrays the footstep that has passed over it; water gives back to the tell-tale surface the body that has been drowned. Fire itself leaves the confession, in ashes, of the substance consumed in it. Hate breaks its prison-secrecy in the thoughts, through the doorway of the eyes; and Love finds the Judas who betrays it by a kiss. Look where we will, the inevitable law of revelation is one of the laws of nature: the lasting preservation of a secret is a miracle which the world has never yet seen.

I have always held the old-fashioned opinion that the primary object of work of fiction should be to tell a story.

~ Wilkie Collins

The books—the generous friends who met me without suspicion—the merciful masters who never used me ill! The only years of my life that I can look back on with something like pride... Early and late, through the long winter nights and the quiet summer days, I drank at the fountain of knowledge, and never wearied of the draught.

~ Wilkie Collins

Men, being accustomed to act on reflection themselves, are a great deal too apt to believe that women act on reflection, too. Women do nothing of the sort. They act on impulse; and, in nine cases out of ten, they are heartily sorry for it afterward.
