That Friday made the last fine day for a month. After Catherine's funeral the weather breaks into sleet and snow; primroses and crocuses vanish under drifts and the larks fall silent. Edgar keeps his room while Nelly converts the lonely parlour into a nursery and rocks the wailing infant at the uncurtained window. Isabella bursts in from the moor, cut and bruised, laughing and out of breath, still in a girlish dress unsuited to marriage, demanding the carriage to Gimmerton. She burns Heathcliff's ring in the coals, refuses dry clothes, and will not stay at the Grange, though she grieved Catherine unreconciled and begged forgiveness through Nelly.
She sits for hours telling what the Heights has become. Heathcliff detests her openly and takes pleasure in making everyone miserable. Hindley drinks while Hareton is degraded under Joseph's sermons and Heathcliff's rule, taught to curse and kept from any gentle schooling. The bridal chamber stays locked against her; scripture becomes cruelty in Joseph's mouth. Isabella describes months of marriage as open war at the Heights while he Heathcliff haunted the Grange by night and nursed revenge against Edgar. She ran the whole way from the Heights except where she flew, unable to count her falls through the blizzard.
On the night after the funeral Hindley tried to shoot Heathcliff through the window; the charge wounded Hindley's own bleeding wrist. Heathcliff trampled and bound him, then left Isabella free to taunt the ruined master. She learned to mock a bound man until Heathcliff threw a dinner-knife at her and she fled across the moor with a cut arm. Heathcliff pursued her to the window shouting Isabella, let me in, or I'll make you repent. Nelly pleads she stay for Catherine's sake and for baby Cathy, but Isabella refuses to wait for Edgar's permission or endure another hour under his roof.
She leaves that day, driven away never to revisit this neighbourhood. Her son Linton is born months later in the south. Edgar becomes a recluse in grief but adores baby Cathy and keeps the Grange closed to the Heights. Heathcliff learns where she lives yet does not take the child, though he threatens that Linton will be his when he chooses. Within six months Hindley drinks himself to death; Heathcliff is master of the Heights, mortgagee of the land, and claims Hareton at the funeral: we'll see if one tree won't grow as crooked as another. Nelly attends Hindley's burial alone while winter seals the Grange and snow builds against the windows where the infant cries. Escape ends one marriage and hands the enemy the house, the debts, and the next boy to ruin while Edgar rebuilds a sheltered world behind closed doors.
Coming Up in Chapter 18
Twelve years will pass in a paragraph while Edgar builds a sheltered world for young Cathy inside the park walls. She grows lovely and restless for Penistone Crags, until Isabella's dying letter summons Edgar abroad and Cathy's curiosity finally carries her beyond the boundaries he enforced.
