Literature
- The Agent Pendergast novel Brimstone has a villain named Count Fosco.
- Bunny: Samantha nicknames her writing professor "Fosco" because she reminds Samantha of "someone hiding maidens in their basement".
- In the Father Brown story "The Pursuit of Mr Blue", Father Brown explains why the murder victim, a wealthy man, was unshaven and dressed in ragged clothes: he was disguised and fleeing for his life, comparing him to Count Fosco dressed as a labourer.
- In Ellen Godfrey's Georgia Disappeared, Jane's first meeting with Georgia is written as a homage to Marian's introduction — Jane first sees Georgia silhouetted in a restaurant doorway, then walking gracefully towards her. Only when Georgia gets close does Jane realise how pretty she isn't.
- The Night Mayor includes Sir Percival Glyde in a scene homaging iconic serial killers from movies of the 1930s and 1940s. (Strictly speaking, it's a homage to Tod Slaughter's character in the extremely loose film adaptation Crimes At The Dark House, rather than to the original novel.)
- Sorcerer Conjurer Wizard Witch: There is a waxwork of Sir Percival Glyde in Madame Tussaud's Chamber of Horrors (along with a number of other fictional villains who are real in the universe of the story). When the villain animates the waxworks and sends them out to rampage in the streets, the waxwork Sir Percival attempts to menace a young lady walking alone and finds out the hard way that young ladies in the 20th century are made of sterner stuff than he's used to.
Music
- Opeth's album Blackwater Park is named after a German Krautrock band which in turn was named after Sir Percival's estate in the novel.
Web Comics
- Hark! A Vagrant: On the Edward Gorey cover Kate Beaton decides to interpret the woman as a bride lost in a cemetery.
