chunk: One night, before leaving for Paris, Basil goes to Dorian's house to ask him about rumours of his self-indulgent sensualism. Dorian does not deny his debauchery, and takes Basil to see the portrait. The portrait has become so hideous that Basil is only able to identify it as his work by the signature he affixes to all his portraits. Basil is horrified, and beseeches Dorian to pray for salvation. In anger, Dorian blames his fate on Basil, and stabs him dead. Dorian then calmly blackmails an old friend, the scientist Alan Campbell, into using his knowledge of chemistry to destroy the body of Basil Hallward. Alan later kills himself over the deed.
