Arthur Conan Doyle,
Rodney Stone — Chapter XXI: The Valet's Story
(1896)
“ It may seem impossible to you that one in my humble walk of life should bear a deadly and implacable hatred against a man in the position of Captain Barrington. You think that the gulf between is too wide. I can tell you, gentlemen, that the gulf which can be bridged by unlawful love can be spanned also by an unlawful hatred, and that upon the day when this young man stole from me all that made my life worth living, I vowed to Heaven that I should take from him that foul life of his, though the deed would cover but the tiniest fraction of the debt which he owed me. ”
