Mélusine is the first book in the Doctrine of Labyrinths series. It is narrated by Felix Harrowgate and Mildmay.
Mildmay tells "the worst story [he] know[s] about hocuses," that of Porphyria Levant and Silas Altamont.
Felix attends a soiree with Shannon Teverius. Robert of Hermione and Agnes Bellarmyn approach them and accuse Felix of lying about his past as a Pharoahlight prostitute. Felix acknowledges the accusations to Stephen Teverius and flees with the knowledge that the news will spread quickly through the Mirador.
