In the prisons at Moscow, offences against discipline are dealt with by the offenders' fellow-prisoners. The convict population on the island of San Stefano compiled spontaneously a Draconian code to quell internal discord arising from racial jealousies.
_Treachery._ This species of morality and justice, which unexpectedly makes its appearance in the midst of a naturally unrighteous community, can only be forced and temporary. When, instead of reaping advantages, interests and passions are injured by acting rightly, these notions of justice, unsustained by innate integrity suddenly fail. Contrary to universal belief, criminals are very prone to betray their companions and accomplices, and are easily induced to act as informers in the hope of gaining some personal advantage or of injuring those they envy or suspect of treachery towards themselves.
"Many thieves," says Vidocq, "consider it a stroke of luck to be consulted by the police." In fact, Bouscaut, one of a notorious band of malefactors in France, was chiefly instrumental in causing the arrest of the gang; and the brigand Caruso aided the authorities in capturing his former companions.
_Vanity._ Pride, or rather vanity, and an exaggerated notion of their own importance, which we find in the masses, generally in inverse proportion to real merit, is especially strong in criminals. In the cell occupied by La Gala, the following notice was found in his handwriting: "March 24th. On this date La Gala learnt to knit." Another criminal, Crocco, tried hard to save his brother, "Lest," he said, "my race should die out." Lacenaire was less troubled by the death-sentence than by adverse criticisms of his bad verse and the fear of public contempt. "I do not fear being hated," he is reported to have said, "but I dread being despised--the tempest leaves traces of its passage, but unobserved the humble flower fades."
Thus thieves are loth to confess that they are guilty of only petty larceny, and are sometimes prompted by vanity to commit more serious robberies. The same false shame is common to fallen women, among whom contempt is incurred, not by excess of depravity but by the failure to command high prices. Grellinier, a petty thief, boasted in court of imaginary offences, with the desire of appearing in the light of a great criminal. The crimes in the haunted castle, attributed by Holmes to himself, were certainly in part inventions. The female poisoner, Buscemi, when writing to her accomplice, signed herself, "Your Lucrezia Borgia."
