Hide and Seek

Hide and Seek was Wilkie Collins' third published novel. It is the first of his novels involving the solution of a mystery, the elements of which are clearer to the reader than to the novel's characters. Suspense is created from the reader's uncertainty as to which characters will find out the truth, when and how.
Hide and Seek was hailed by both contemporary and modern critics to be an advance on his previous work, the sensational melodrama Basil, though inferior to The Woman in White and other novels of his mature period. (wikipedia.org)
