Young orphan Esther Summerson is brought to the High Court of Chancery, where she is thrown together with two wards of the court, Richard Carstone and Ada Clare. Both are caught up in the infamous suit of Jarndyce and Jarndyce, which brings nothing but ruin and despair to all it touches. Esther, Richard and Ada are sent to live at Bleak House, where they receive a friendly welcome from their rich guardian John Jarndyce.

As Tulkinghorn edges closer to the truth, Lady Dedlock puts her reputation at risk when she pays an undercover visit to Nemo's former haunts. John Jarndyce finds himself increasingly attracted to Esther, but Richard makes an announcement which causes him dismay. And Woodcourt has news that comes as a terrible blow to Esther.

Richard's inability to settle causes a rift with John Jarndyce, much to Ada's dismay. Tulkinghorn finally unearths the possible identity of the mysterious Nemo. Nemo's old friend Sergeant George has the evidence he needs to prove it and Tulkinghorn will stop at nothing to force George to hand it over. But George has even more problems when Gridley turns up on his doorstep, on the run from the law and infected with the fever.

Esther is shattered by Lady Dedlock's revelation. Richard's obsession with the Jarndyce case has grown to worrying proportions. Guppy puts himself at risk when he gets in the way of Tulkinghorn's enquiries. And Tulkinghorn at last has cast iron proof of Lady Dedlock's guilt, and issues her with a terrible ultimatum.

Richard's obsession with Chancery has left him desperately ill. Ada is pregnant but worries Richard will not live to see the child. When Woodcourt proposes marriage, Esther is torn between her love for him and her commitment to Jarndyce. The impossible finally happens - a result in Chancery - but it's one that will astound everybody.
