Mr. Wilkie Collins brings to his work, along with other and valuable qualities, the special talent of the private detective and the criminal lawyer. Almost no modern novelist stands in any comparison with him for skill in constructing the engrenage, as a Frenchman would call it, of personal complication, for subtle delicacy in fitting together wheel and spring, pivot and pinion of his dramatic clockwork, in such fascinating interplay as shall lead the attention of the breathless spectator smoothly, imperceptibly, but inevitably to the final wind-up of the catastrophe. This skill in combining events is supplemented by, or rather cognate with, his shrewd analysis of character and motive. It is his favorite plan to suppose a case of private relation where virtuous personages or important interests are threatened by the schemes of some clever villain. Against him Mr. Collins, in the person of his beneficent and equally clever hero or heroine, straight sets his wits to defend the interests or persons attacked. The resulting struggle is carried on with the most exquisite skill of fence, involving both practical device and metaphysical penetration and shrewdness, till the final triumph of the right and confusion of the wrong-doers. In this book the metaphysical element assumes unusual importance. The book is in so far an exception to the usual run of Mr. Collins's works, that it is less a leaf from the records of Scotland Yard than an extract from the diary of a psychologist. There is a villain and a protecting genius, as usual ; but the villain is only a half one after all, and we are less interested in the actual facts of his rascality than in the causes which lead him to it, and the temperament which renders it possible. In the leading character, poor Miss Finch herself, the author develops an interesting question of medical psychology. A young girl, blind almost from her birth, loves one of two twin brothers, who has, in the process of medical treatment for epilepsy, been terribly disfigured in complexion by the use of nitrate of silver. From Lucilla's instinctive horror of dark objects, the injudicious and timid concealment by the lover of his dusky hue, and the treacherous advantage taken of these things by the other twin, Nugent, to supplant his brother – the whole complicated by Lucilla's temporary restoration to sight and subsequent relapse – arises the whole intrigue of the story …
