I am unwilling to suffer this tale to leave my hands without a word of explanation to my reader. If I have never disguised from myself the grounds of any humble success I have attained to as a writer of fiction; if I have always had before me the fact that to movement and action, the stir of incident, and a certain light-heartedness and gayety of temperament, more easy to impart to others than to repress in one's self, I have owed much, if not all, of whatever popularity I have enjoyed, I have yet felt, or fancied that I felt, that it would be in the delineation of very different scenes, and the portraiture of very different emotions, that I should reap what I would reckon as a real success. This conviction, or impression if you will, has become stronger with years and with the knowledge of life; years have imparted, and time has but confirmed me in, the notion that any skill I possess lies in the detection of character, and the unravelment of that tangled skein which makes up human motives.
