I'm reading this at the moment and loving it, although I can't say I like any of the characters very much, least of all the spoilt, selfish, whinging little nincompoop, Linton!
Heathcliff can be quite funny at times in his cynical, uncaring way.
Speaking of his preference for nephew Hareton, over Linton his son he says, "I'll pit him against that paltry creature, unless it bestir itself briskly. We calculate it will scarcely last till it is eighteen. Oh, confound the vapid thing! He's absorbed in drying his feet, and never looks at her - Linton!"
(Has anyone seen the Wuthering Heights version with Tom Hardy and Charlotte Riley? Tom made a heart-stopping Heathcliff )
