Dictation in Porphyria's Lover

The author starts the poem by setting the calm mood when the woman comes in from out of the rain and finds warmth and comfort in his arms "she shut the cold out and the storm" (719) "she put my arm around her waist" (719). Later in the poem he strangles her in fear that she may leave him but the mood of the poem never alters it remains calm "In one long yellow string I wound three times her little throat around" (720) he feels no remorse at all it seems very natural he even sits her next to him later "and thus we sit together now, and all night long we have not stirred" (720).
