After Karel disappears, Helen learns, through documents he leaves behind, of other people who, over the centuries, appear to have been haunted by Melmoth. It is Karel who introduces Helen to the mythical figure of “Melmoth”, about whom he is becoming obsessed. Lonely and melancholic, not unlike Melmoth herself, Helen finds some warmth in her friendship with academic Karel and his English lawyer wife Thea. Melmoth’s character provides a link between the different episodes, but there is also an overarching frame story featuring one Helen Franklin, an Englishwoman working as a translator in Prague. Thus the novel is a matryoshka doll of stories within stories, most which are based on “found” documents or related by unreliable narrators. Structure-wise, Perry takes a leaf from Maturin’s book and from other Gothic classics such as Potocki’s "Manuscript found in Saragossa".

Like Maturin’s Melmoth, she also seeks individuals as desperate as she is – except that rather than wanting them to replace her, she tries to lure them to accompany her on her guilt trip. Rather than merely a temptress or wanderer, however, Perry’s Melmoth is, first and foremost, a “witness”: ever waiting, ever watching, listening and remembering the darkest and guiltiest secrets, ‘lest we forget’. This has echoes of the tale of the Wandering Jew, one of several myths and legends subtly evoked by Perry for added resonance. Sarah Perry recasts Melmoth as a black-clad woman, damned to roam the Earth after denying the Resurrection of Jesus, feet bloody from her lonely travels. 'At this moment is there one of us present, however we may have departed from the Lord, disobeyed his will, and disregarded his word–is there one of us who would, at this moment, accept all that man could bestow, or earth afford, to resign the hope of his salvation?–No, there is not one–not such a fool on earth, were the enemy of mankind to traverse it with the offer!' Maturin, an Irish Protestant clergyman who, when not writing novels and plays, applied his skills to composing fiery sermons, stated in the preface to Melmoth that the germ of “this Romance (or Tale)” was to be found in one of his homilies: This turns out to be a surprisingly challenging task. As the end of his extended term approaches, Melmoth searches the world for someone desperate enough to take his place. Maturin’s protagonist is a Faustian character who strikes a deal with the Devil, selling his soul for a new lease of life. In this case, however, the religious elements also betray the influence of Charles Maturin’s Melmoth the Wanderer, an 1820 novel which serves as the inspiration and model for Perry’s book.

Perry has never made a secret of her strict religious upbringing and the impact which it has had on her writing. Sarah Perry's brand of Gothic is an existential one, where theological concepts of sin, guilt and redemption are writ large.
