Arthur Conan Doyle said this quote

From the first day I met her, she was the only woman to me. Every day of that voyage I loved her more, and many a time since have I kneeled down in the darkness of the night watch and kissed the deck of that ship because I knew her dear feet had trod it. She was never engaged to me. She treated me as fairly as ever a woman treated a man. I have no complaint to make. It was all love on my side, and all good comradeship and friendship on hers. When we parted she was a free woman, but I could never again be a free man.

~ Arthur Conan Doyle

A man always finds it hard to realize that he may have finally lost a woman's love, however badly he may have treated her.

~ Arthur Conan Doyle

Life is infinitely stranger than anything which the mind of man could invent.

~ Arthur Conan Doyle

When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.
