Catherine married Edgar and was happy for half a year, in the way a river is calm above a weir. Then on a September evening a man came up the walk at the Grange, tall, upright, soldierly, with black eyes full of a subdued fire. Heathcliff had been gone three years, and nobody ever learned where the money came from. Catherine's joy frightened her husband. Heathcliff took lodgings at Wuthering Heights and won the whole estate from Hindley at cards, night after night, while Hindley drank himself towards the grave. Then Isabella Linton, Edgar's sister, fell in love with the idea of him. Catherine warned her that he was an unreclaimed creature, a wilderness of furze and whinstone. Isabella thought she was jealous, and eloped with him in March, and was never happy again.
