What is the author's style in Porphyria's Lover by Robert Browning?

"Porphyria's Lover" is a dramatic monologue, a poem in which a speaker talks to a silent listener about a dramatic event or experience. Browning is considered to be one of the earliest and greatest practitioners of this form, and "Porphyria's Lover" is his first poem in this style. The dramatic monologue offers readers intimate insight into the speaker's changing thoughts and feelings because he presents in his own words how he sees and understands the situation he discusses. However, as becomes clear in "Porphyria's Lover," much of what the reader learns about the speaker of the monologue comes not from the speaker's own revelations but from what he does not say. The speaker in "Porphyria's Lover," for example, never declares that he is mad, but the reader infers from his words that he must be. The speaker also means to convince (perhaps himself) that his actions are justified, but there are clues that he may not actually feel this way, and certainly the reader can decide, after considering what has happened, how the speaker should be judged. One of the most interesting features of the dramatic monologue is that it presents a situation through the words and thoughts of a particular character, but then it is up to the reader to decide to what extent that character's actual depiction of the events should be believed. With "Porphyria's Lover," the reader must determine by reading between the lines of the speaker's account how reliable a narrator he is, how accurate his portrayal of Porphyria is, what his intention is in recounting the story, and exactly what is the extent and nature of his madness.
