Norman Lock recounts the story of a young Philadelphian, Edward Fenzil, who, in the winter of 1844, falls under the sway of two luminaries of the nineteenth-century grotesque imagination: Thomas Dent Mütter, a surgeon and collector of medical "curiosities," and Edgar Allan Poe. As Fenzil struggles against the powerful wills that would usurp his identity, including that of his own malevolent doppelgänger, he loses his mind and his story to another.
