The second work, _Pickwick,_ written in a harum-scarum way, is even more typical of Dickens in its spirit of fun and laughter. He had been engaged, as we have noted, to furnish a text for some comic drawings, thus reversing the usual order of illustration. The pictures were intended to poke fun at a club of sportsmen; and Dickens, who knew nothing of sport, bravely set out with Mr. Winkle on his rook-shooting. Then, while the story was appearing in monthly numbers, the illustrator committed suicide; Dickens was left with Mr. Pickwick on his hands, and that innocent old gentleman promptly ran away with the author. Not being in the least adventurous, Mr. Pickwick was precisely the person for whom adventures were lying in wait; but with his chivalrous heart within him, and Sam Weller on guard outside, he was not to be trifled with by cabman or constable. So these two took to the open road, and to the inns where punch, good cheer and the unexpected were awaiting them. Never was such another book! It is not a novel; it is a medley of fun and drollery resulting from high animal spirits. [Sidenote: THE MOTIVE OF HORROR] In his next novel, _Oliver Twist_, the author makes a new departure by using the motive of horror. One of his heroes is an unfortunate child, but when our sympathies for the little fellow are stretched to the point of tears, Dickens turns over a page and relieves us by Pickwickian laughter. Also he has his usual medley of picturesque characters and incidents, but the shadow of Fagin is over them all. One cannot go into any house in the book, and lock the door and draw the shades, without feeling that somewhere in the outer darkness this horrible creature is prowling. The horror which Fagin inspires is never morbid; for Dickens with his healthy spirit could not err in this direction. It is a boyish, melodramatic horror, such as immature minds seek in "movies," dime novels, secret societies, detective stories and "thrillers" at the circus. In the fourth work, _Nicholas Nickleby_, Dickens shows that he is nearing the limit of his invention so far as plot is concerned. In this novel he seems to rest a bit by writing an old-fashioned romance, with its hero and villain and moral ending. But if you study this or any subsequent work of Dickens, you are apt to find the four elements already noted; namely, an unfortunate child, humorous interludes, a grotesque or horrible creature who serves as a foil to virtue or innocence, and a medley of characters good or bad that might be transferred without change to any other story. The most interesting thing about Dickens's men and women is that they are human enough to make themselves at home anywhere.
