Tone of Porphyria's Lover

The author of “Porphyria’s Lover” uses an unattached tone by the speaker of the story to stun the readers at the end. He begins by telling of this woman that he desires to love him but cannot believe she actually would. She has traveled through a storm to be with him and insists she does love him “murmuring how she loved me-she / Too weak, for all her heart’s endeavor”(21). She is almost exhausted by her own desires for him and when he realizes it he was “Happy and proud; at last I knew / Porphyria worshipped me; surprise / Made my heart swell…” (32). The tone of the story doesn’t change as he now struggles with wondering what to do next “Perfectly pure and good:I found / a thing to do…”(37).Then the surprise ending that shocks the readers as he strangles her with her own hair so that he can keep her love forever. He has the same tone throughout the poem even as he tells how he sits her up beside him all night long, having no remorse for what he done.
