The Woman in White by Wilkie Collins

“This correspondence, by a meeting between some of the parties, and a separation between the others, could not, to the great detriment of the Post Office revenue, be continued any longer. Very little assistance to the State could be derived from the epistolary intercourse of Mrs. Vernon and her niece; for the former soon perceived, by the style of Frederica’s letters, that they were written under her mother’s inspection! and therefore, deferring all particular enquiry till she could make it personally in London, ceased writing minutely or often.” -an excerpt
