A novel of high aim requires, of course, delineation of character, and with more patient minuteness, than the drama; and some novels live, indeed, solely through the delineation of character; whereas there are some tragedies in which the characters, when stripped of theatrical costume, are very trivial, but which, despite the poverty of character, are immortal, partly from the skill of the plot, partly from the passion which is wrought out of the situations, and principally, perhaps, from the beauty of form—the strength and harmony of the verse. This may be said of the French drama generally, and of Racine in especial. The tragic drama imperatively requires passion—the comic drama humour or wit; but a novel may be a very fine one without humour, passion, or wit—it may be made great in its way (though that way is not the very highest one) by delicacy of sentiment, interest of story, playfulness of fancy, or even by the level tenor of everyday life, not coarsely imitated, but pleasingly idealised. Still mystery is one of the most popular and effective sources of interest in a prose narrative, and sometimes the unravelling of it constitutes the entire plot. Every one can remember the thrill with which he first sought to fathom the dark secret in ‘Caleb Williams’ or ‘The Ghost-Seer.’ Even in the comic novel, the great founder of that structure of art has obtained praise for perfection of plot almost solely from the skill with which Tom Jones’s parentage is kept concealed; the terror, towards the end, when the hero seems to have become involved in one of the crimes from which the human mind most revolts, and the pleased surprise with which that terror is relieved by the final and unexpected discovery of his birth, with all the sense of the many fine strokes of satire in the commencement of the tale, which are not made clear to us till the close.
