Masquerade in Lodi (Penric & Desdemona, 9) [Bujold, Lois McMaster]

Bastard's Eve is a night of celebration for most residents in the canal city of Lodi--but not for sorcerer Learned Penric and his Temple demon Desdemona, who find themselves caught up in the affairs of a ship, a lost madman, a dangerous ascendant demon, and a very unexpected saint of the fifth god. This novella falls between Penric's Fox and Penric's Mission in the internal chronology of the Penric & Desdemona tales.
