Israel Zangwill,
The Big Bow Mystery — Chapter IV
(1895)
“ I do not for one moment believe that Arthur Constant killed himself, and if Scotland Yard satisfies itself with that explanation, and turns on its other side and goes to sleep again, then, sir, one of the foulest and most horrible crimes of the century will forever go unpunished. My acquaintance with the unhappy victim was but recent; still, I saw and knew enough of the man to be certain (and I hope I have seen and known enough of other men to judge) that he was a man constitutionally incapable of committing an act of violence, whether against himself or anybody else. ”
