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) and her downstairs neighbor (Mme L'Amour, the baker's wife) are from Sweeney Todd
• 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.
