Bleak House opens not with a character but with weather. Fog lies over London, thickest of all around the Court of Chancery, where the endless lawsuit Jarndyce and Jarndyce drones on. The case is a dispute over conflicting wills that has run for so many years that the original parties have died, the lawyers profit, and nobody can any longer say what it is about. Dickens presents the court as a place that ruins the people who trust it, and the fog of the first pages becomes the book's standing image for institutions that thrive on confusion.
Against this public satire the novel sets a private narrator. Roughly half the chapters are told by Esther Summerson, a quiet young woman raised by a severe godmother and never told who her parents were. She is taken in, along with two other young wards of the suit, Richard Carstone and Ada Clare, by the kindly John Jarndyce at the country house called Bleak House. The other half of the book is told by an unnamed third-person voice in the present tense, ranging across a much wider world, from the aristocratic Dedlocks down to a crossing-sweeper boy named Jo. The two narrations alternate and slowly converge.
The hidden engine of the plot is a secret. Lady Dedlock, the proud and bored wife of Sir Leicester Dedlock, glimpses a familiar handwriting on a legal document and nearly faints. The hand belongs to a destitute law-writer, and her reaction sets the lawyer Tulkinghorn hunting for what she is concealing. The buried truth reaches back into Esther's own origins and ties the great house in Lincolnshire to the poorest streets of the city, so that the fashionable and the forgotten turn out to be parts of one connected society.
As the secret is tracked, the lawsuit keeps quietly destroying. Richard Carstone, sure that the case will make his fortune, gives up every other path in life to wait on a verdict, and the waiting wears him down. When a murder brings in Inspector Bucket, an early fictional detective, the strands of the novel are gathered together in a long pursuit across a winter landscape, ending in grief rather than rescue. Esther herself survives illness and disfigurement and comes through to a settled life and a marriage of her own choosing.
Jarndyce and Jarndyce finally ends, but not with a judgment. A later will is found, and then it is discovered that the costs of the suit have eaten the entire estate, so the case simply lapses and dissolves while clerks carry out great bundles of paper and laugh. The disputed money is gone. The book closes on Esther's quiet contentment and on the larger verdict underneath the whole story: that a system can grind on for its own sake, long after it has stopped serving anyone, and that the human damage is the real reckoning.
