“Novel-writing has in one respect an affinity to the drama—that time and distance are required to soften for use the harsher features that may be exhibited from real life; that it was almost impossible to bring forward events without touching on their causes; and that any tendency to political discussion, however liberal or applicable, was not to be tolerated in a sort of work which people took up with no other design than to be amused at the least possible expence of thought.”
