A murderer is less loathsome to us than a spy. The murderer may have acted on a sudden mad impulse; he may be penitent and amend; but a spy is always a spy, night and day, in bed, at table, as he walks abroad; his vileness pervades every moment of his life
Honore de Balzac (2014). “The Elixir of Life”, p.5, The Floating Press
