Consider this quotation attributed to Eugene Sue:
Virtue, alas! not infrequently trips and falls on the sharp-edged rock of poverty.
It has been attributed in the work "The Mysteries of Paris" but a search of the four English tr. volumes has not borne fruit. Neither any luck at sites like babelio, so perhaps the default Google translation is missing something.
La vertu, hélas! fréquents voyages et tombe sur le rocher acéré de la pauvreté
Any alternatives to help locate a source? Thanks.
