The greatest novel by the greatest novelist England has ever produced, and in my opinion, the greatest novel in the language. That is how highly I regard this novel.
Bleak House is a giant book by any measure, physical or literary, triumphantly covering so much ground that it successfully paints a multi-faceted, multi-layered portrait of the whole culture and society of the Victorian Age in Britain. Bleak House is a savage satire upon the class system, the law, politics, and public morality. At the same time it is a wonderful crime novel of murder and detection, a love story, a comedy, and a piece of high Victorian melodrama. Yes, Bleak House is all these things and more.
In addition, the novel also displays Dickens' artistry as a writer of prose to the full. The famous first chapter alone - which consists almost entirely of a magnificent description of a foggy day in November - is a masterpiece of English prose. From there onwards the standard of writing never slips.
Dickens' is justly famous for the wonderful casts of characters he assembled for his novels and here again, Bleak House doesn't disappoint. It boasts a vast and interesting array of characters, especially Mr Jarndyce, Esther Summerson (the partial narrator and heroine of the book), Jo the crossing sweeper whose story will break your heart, the villainous Mr Tulkington, and the detective Inspector Bucket, one of the first detectives to appear in fiction.
I rate Bleak House as Dickens' most mature, supreme achievement as a writer. The satire is biting. The moral indignation at the injustices of the world is brave and honest. As a whole experience, no reader can afford not to read classics like Bleak House at least once. If you do miss out, you're only letting the finest things in life (reading life anyway) pass you by.
