Helvetica Spot-the-Ref

Miseri spends inordinate amount of time putting in references, so it would be a pity not to write down the stuff we notice:

• Helvetica and Geneva are fonts, of course
• The Pervenches are the kids from Narnia, complete with disappearance into wardrobe
• Louise Beauclair (the barber's wife), her downstairs neighbor (Mme L'Amour, the baker's wife), and Judge Dupin are from Sweeney Todd, though the events therein had not yet taken place when we met them.
• Lucille (the vampire) is eventually buried in a tomb with Wilhelmina Murray
• Lucille also attacks Camilla Karnstein, in a reversal of Carmilla (and note we also have a Laura)
• Sir Galahad Locksley's name is at least three refs (Tennyson's Sir Galahad (he's a poet); Locksley, for Robin of Locksley; and Gilderoy Lockhart)
• Obviously we have a Scarlet Pimpernel thing going on with rescuing folks from Bois-Franc, but there haven't been any explicit refs as far as I've noticed
• Maria von Pinn and some students are from The Sound of Music, and her surname is undoubtedly a reference to Von Pinn from Girl Genius
• Adelheid Sessemann is from Heidi
• Dupin is (I assume, though there's no evidence besides his name and nationality) Auguste Dupin
• Cujo the Alsatian is of course Cujo, and despite being named for this fictitious monastery, the Alsatian is a real-world breed better known as the German Shepherd
• St. Alsace is (I assume) referencing Alsace, a region with similar geography to Helvetica.
