In most episodes (including the pilot) J. B. Fletcher's first novel is referred to as "The Corpse Danced at Midnight", in this episode it is referred to as "The Corpse Danced Alone". Jessica even calls it "The Corpse at Midnight".
The Russian egg-hunter tells Jessica he represents "Nevsky Publishing, Moscow". This doesn't make sense, as the word "Nevsky" is directly synonymous with St. Petersburg. It means "of/on the river Neva", which runs through the city.
