Émile Gaboriau said this quote

It is at the family fireside, often under the shelter of the law itself, that the real tragedies of life are acted; in these days traitors wear gloves, scoundrels cloak themselves in public esteem, and their victims die broken-hearted, but smiling to the last. What I have just related to you is almost an every-day occurrence; and yet you profess astonishment.
